Solar fuels via engineering innovation | EPSRC | The quest for sustainable resources to meet the demands of a rising global population is one of the main challenges for humanity this century, with global energy needs set to double by 2050. This is set against the backdrop of increasing CO2 emissions and associated climate change, and the ambitious target set out in the recent UK Fourth Carbon Budget of a 50 cut in CO2 emissions by 2025. Solar energy can be used to drive the conversion of CO2 into fuels via a process called photocatalytic reduction. The utilisation of CO2 as an alternative fuel represents an attractive strategy to address both the consumption of non-renewable fossil fuels and global warming, while offering sustainable, safe and useful carbon capture. This research is being carried out by Heriot-Watt University. | £1,179,790 | 2013 - 2018 | |
SUPERSOLAR Solar Energy Hub | EPSRC | The SUPERSOLAR Hub of Universities has been set up to co-ordinate research activities, establish a network of academic and industrial researchers, conduct cross-technology research and provide a focus for international co-operation. SUPERSOLAR is led by CREST at Lough-borough University and supported by the Universities of Bath, Liverpool, Oxford, Sheffield and Southampton. This group is active in all of the PV technologies including new materials, thin film chalcopyrite, c-Si, thin film a-Si, dye sensitised solar cells, organic PV, concentrator PV, PV systems performance and testing. SUPERSOLAR will set up a solar cell efficiency measurement facility for the benefit of the PV community in the UK. The consortium contains a deliberate balance of expertise, with no bias towards any one technology. | £4,088,360 | 2012 - 2017 | |
High Performance Vacuum Flat Plate Solar Thermal Collectors for Hot Water and Process Heat | EPSRC | The aim of the proposed research by the University of Warwick is to provide the necessary knowledge to allow the development of a pre-prototype High Performance Vacuum Flat Plate Solar Thermal Collector with minimal materials content. The development of a thin evacuated solar collector offers new and exciting prospects for integrating solar collectors into building designs and for their use in medium temperature (100-200 Celsius) applications such as air conditioning or low temperature process heat. The research planned will develop technology for the effective utilisation of the solar energy resource and fits within EPSRC’s Energy theme. Solar thermal energy is predicted to be a significant growth market with the potential to make a significant contribution to reducing fossil fuel use in the building energy sector. The research is targeted at providing new knowledge and techniques that will enable the advances in technology necessary for a step change in solar thermal collector performance to be realised and a range of new products and application areas developed. Such new products will encourage inward investment and lead to the creation of new companies that can contribute significantly to the transition to a low carbon society whilst maintaining and improving quality of life. | £302,411 | 2013 - 2016 | |
Rational design of solid-state semiconductor-sensitized solar cells: from materials modelling to device fabrication | EPSRC | In this project we take the first step along this direction by focussing primarily on the electronic energy-level alignment at the sensitizer/oxide interface. The interfacial energy level alignment is directly related to the open-circuit voltage of sensitized solar cells and is a key design parameter for improving cell efficiencies. Our proposed rational design will consist of the following steps: (i) identify promising sensitizers via computational modelling, (ii) synthesize and characterize the selected materials, (iii) fabricate and optimise the solar cells, and (iv) perform advanced spectroscopy to understand the fundamental operation and limiting factors to performance in complete solar cells. This synergistic use of first-principles modelling and experiment has not been attempted so far in nano-photovoltaics research and has the potential of revolutionizing the field. Owing to our complementary skills, our research team is unique in the UK and EU arenas and this project holds the promise for revolutionizing our understanding of sensitized solar cells at the nano- scale, and introducing and developing paradigm-shifting technology. In this project we will focus specifically on solid-state semiconductor-sensitized solar cells. These devices are an evolution of the concept of dye-sensitized solar cells whereby the dye sensitizer is replaced by a semiconductor quantum dot or a nano-scale semiconducting film. This choice has three advantages: (I) the expensive transition-metal based dye sensitizer is replaced by a inexpensive light-absorber obtained by colloidal synthesis (ii) the optical properties of the sensitizer can be tuned by exploiting quantum size effects, and (iii) in comparison to conventional thin film photovoltaics, there is a much broader library of materials which may work effectively as semiconductor sensitizers. This research is being carried out by the University of Oxford. | £989,490 | 2012 - 2016 | |
Sustainable Product Engineering Centre for Innovative Functional Industrial Coatings - SPECIFIC | EPSRC | The shared vision for SPECIFIC is to develop affordable large area solar collectors which can replace standard roofs and generate over one third of the UK’s total target renewable energy by 2020 (10.8 GW peak and 19 TWh) reducing CO2 output by 6 million tonnes per year. This will be achieved with an annual production of 20 million m2 by 2020 equating to less than 0.5 of the available roof and wall area. SPECIFIC will realise this by quickly developing practical functional coated materials on metals and glass that can be manufactured by industry in large volumes to produce, store and release energy at point of use. These products will be suitable for fitting on both new and existing buildings which is important since 50 of the UKs current CO2 emissions come from the built environment. The key focus for SPECIFIC will be to accelerate the commercialisation of IP, knowledge and expertise held between the University partners (Swansea, ICL, Bath, Glynd r, and Bangor) and UK based industry in three key areas of electricity generation from solar energy (photovoltaics), heat generation (solar thermal) and storage/controlled release | £5,012,105 | 2011 - 2016 | |
Efficiency Enhancement of Silicon Photovoltaic Solar Cells by Passivation | EPSRC | The aim of this proposal is to develop methodologies which are able to bring the efficiency of cells made from cheap forms of silicon close to the efficiencies achieved from the higher cost electronic grade material. This could increase the efficiency of multi-crystalline solar grade silicon by around 5 absolute and even more in the case of upgraded metallurgical silicon. Current silicon cell structures work well because hydrogen (usually from the silicon nitride antireflection layer) passivates surfaces and bulk defects. In electronic grade single crystal this reduces recombination to insignificant levels. It doesn’t work as well in solar grade multi-crystalline silicon or upgraded metallurgical silicon because there are regions, sometimes entire crystal grains, which are not passivated by the hydrogen. However other regions are of very high quality often as good as electronic grade silicon. We associate the resistance to passivation with specific types of defect observed in lifetime maps of slices. In this project we plan to identify the defects which show resistance to hydrogen passivation by using electronic and chemical techniques (carrier lifetime, Laplace deep level transient spectroscopy, SIMS, Raman spectroscopy and defect modelling). The key part of the proposal is to use our knowledge of defect reactions in silicon to develop alternative passivation chemistries which can be applied, during slice or cell production, to those defect species resistant to hydrogen passivation. In this way we would expect to make a very important improvement to the efficiency of the dominant solar PV technology. This research is carried out by the University of Manchester, Elkem ASA, National Renewable Energy Laboratory, Fraunhofer, University of Aveiro, University of Oxford, MEMC Electronic Materials SpA. | £516,973 | 2012 - 2015 | |
Development and Integration of Biomass and Concentrating Photovoltaic System for Rural and Urban Energy Bridge: BioCPV | EPSRC | This project addresses the issues related to integrated solar photovoltaic system - converting incoming solar energy into electricity and biomass power technologies - generation of electrical power from waste materials, for rural electrification. This project seeks to develop a new class of solar photovoltaic technologies - Concentrating Photovoltaic (CPV) to integrate with Biomass and waste power generation as a backup source and develop high efficiency hydrogen generation and storage from the integrated systems. The integrated system will be installed at Uttar Sehalai Tribal Hamlet, located in a remote village, 200km west of Calcutta for rural electrification with key focuses on satellite based remote monitoring technologies. The project will brings together Biomass, Concentrating Photovoltaic, and Hydrogen Generation and Storage expertise from University of Leeds, Heriot-Watt University, University of Nottingham in the UK and Visva-Bharati University, Santiniketan, Indian Institute of Technology Madras, PSG College of Technology in India with the goal of developing a low cost autonomous power generating system for rural electrification. | £1,401,637 | 2011 - 2013 | |
Photovoltaics for Future Societies | EPSRC | Globally, humanity faces profound challenges in meeting increasing energy demand in the face of climate change and peak oil. The development and application of small-scale technologies for energy conversion and energy efficiency is an essential component amongst the collection of strategies that will be necessary to confront these challenges. Technological progress in this field is swift with new development promising leaps in cost reduction, efficiency and in flexibility of application. However, regardless of technical efficiency, new technologies will only make a difference as long as they are successfully integrated into people’s living environments. First generation PV is well established as part of low carbon energy strategies, most notably in highly developed states like Germany and Japan. Its application is now extending rapidly as efficiencies improve and costs come down as a result of government support. Nevertheless, PV has vast unrealised potential, as a relatively efficient means of generating electricity which can be utilised in a far wider range of situations than competing technologies like wind, water or biomass. PV is therefore uniquely disruptive in its potential to eventually enable most consumers of energy to become producers of energy. The realisation of this potential will require significant further reductions in cost along with a massive increase manufacturing volumes. This research is being carried out by the University of Sheffield. | £1,366,123 | 2011 - 2015 | |
New Materials and Devices for Photovoltaic Applications | EPSRC | With the advent of global warming, rapidly increasing demand for energy, and concerns over the security of supply of traditional carbon based fuels the requirement for alternative, sustainable energy sources is recognised throughout the world. Photovoltaics (PVs) harvest electrical energy directly from sunlight, delivering power at the point of use and are potentially a major component of the long term solution to this growing challenge. There is a rapidly growing worldwide focus on the development of new third generation PV technologies which offer the prospect of significantly improved performance and/or low cost manufacture, thus helping to accelerate commercial exploitation and large-scale deployment. New PV technologies will require innovations in materials, concepts and devices and the unique and flexible nature of Platform Grant funding will help the group at the University of Warwick tackle this important strategic challenge. | £1.3m | 2010 2015 | |
Energy Futures DTC | EPSRC | We propose an Energy Futures Doctoral Training Centre that provides depth and breadth in PhD training in energy and its role in climate change mitigation. This will integrate with other energy DTCs recently awarded by EPSRC, but will not offer the full 12 month training programme associated with other fully funded DTCs. Our DTC will focus on future energy generation and distribution, aimed in particular on the role of the energy sector in achieving the UK’s ambitious mitigation goals required to meet the challenge of climate change. It will accept 10 of the very best science and engineering graduates annually, funded by a strategic investment from Imperial College, and supported by industry. Breadth will be provided by our existing energy-wide training experience at MSc level, and established links between the Energy Futures Lab and the Grantham Institute for Climate Change at Imperial College, and by the inter-department and inter-faculty research linkages forged through existing and future interdisciplinary research projects. Depth is provided by our energy research networks and the research teams behind them, which we link by collectively addressing critical and cross-cutting research questions, such as how can we improve the energy efficiency of cities of the future , and how can we decarbonise energy generation . We will further develop this integrating approach within our Energy Futures DTC to link students across our energy themes, and ensure that students are given exposure to the broad energy, climate change and sustainability context. | £443,507 | 2010 - 2015 | |
Boronic Acids for Dye Sensitised Solar Cells | EPSRC | An excellent class of solar cell (dye sensitised solar cell DSSC) operates in a similar manner to photosynthesis. Whilst current technology is good there is still much room for improvement. The dyes used in DSSCs can themselves have detrimental environmental impacts as well as be costly and have a short operating lifetime. This project will provide new dyes that offer significant improvements relating to all these points taking a giant leap forwards to realising solar electricity generation as a cheap reliable technology for all. This research is being carried out by the University of Birmingham. | £87,254 | 2012 - 2014 | |
Microstructural evolution of CdTe-based solar cells during chlorine activation | EPSRC | The purpose of the programme carried out by Durham University is to identify the dominant mechanism(s) underpinning chlorine activation as well as rapid screening of potential processing routes designed to optimise solar cell efficiency. The latter is a paradigm shift in solar cell fabrication methodology, moving away from methods based on trial and error, which are time consuming and costly. | £102,124 | 2012 - 2014 | |
Solar cells based on InGaN nano-structures | EPSRC | One requirement in reducing greenhouse gases is for high efficiency multijunction solar cells (MJSCs) to extract power from concentrated solar power (CSP) plants, which are expected to become central to the delivery of solar power to national and super-grid systems. At present such MJSCs must combine different materials systems, and are usually limited by the requirement to lattice-match the individual cells to avoid efficiency losses due to defects. In this proposal we aim to circumvent these problems by investigating solar cells based on InxGa1-xN, which has a direct band gap of 0.7-3.4 eV, spanning most of the visible spectrum, thus promising MJSCs from a single materials system. To avoid the problems of lattice mismatch and of material quality, which limit prototype solar cells based on InxGa1-xN epilayers to low x (x<0.3), we will grow the InxGa1-xN in nano-rod form, merging the nano-rods using methods we have already developed to provide a solar cell template. This research is being carried out by the University of Bristol, University of Nottingham and the Arizona State University. | £429,592 | 2011 - 2014 | |
Luminescent Lanthanide Layers for Enhanced Photovoltaic Performance (LEAP) | EPSRC | It is now widely accepted that the world’s increasing reliance on fossil fuels over recent centuries is causing drastic changes in the Earth’s climate. Renewable energy technologies - such as solar, wind and wave energy - offer a pathway for the generation of clean energy. This project concerns photovoltaic (PV) technology - the conversion of sunlight to electricity - and, in particular, involves the application of luminescent materials to PV modules. Shipments of PV modules have been increasing at a steady rate of >40 per annum since 1994 and continued strong growth of 20-30 predicted for the next few years. However, efficiency and price are still the main barriers to reducing the cost of solar electricity. This project seeks to develop a new class of PV devices and modules, based on today s semiconducting technology however utilising luminescent materials to alter the wavelengths contained in the sunlight before the photons interact with the solar cell. Via two techniques known as down-conversion (DC) and up-conversion (UC), we are able to greatly address two of the main loss mechanisms that limit the theoretical performance of a single junction solar cell to about 30 . With DC, we are able to use luminescent materials to absorb photons in the range of 300-500nm (UV through to blue-green light) and for each of these emit TWO photons at about 1000nm, where silicon solar cells respond very efficiently. Preliminary modelling has indicated that such a DC layer applied to the front of a silicon solar cell could increase its absolute energy conversion efficiency (sunlight to electricity) from 16 for a typical production device to 19 . Thus, a huge step change in performance is possible. UC layers are able to collect near-infrared (NIR) light that passes straight through the silicon, and for each of these NIR photons we can emit a single higher-energy photon that can be harvested by the silicon solar cell. The performance of UC layers depends on the intensity of sunlight though, and hence we will design and test these systems under 500-times concentrated sunlight. This project brings together spectral conversion and PV expertise from Heriot-Watt University (HWU) in the UK and matches this with luminescent materials expertise from the Fujian Institute of Research on the Structure of Matter (FJIRSM), one of the Chinese Academy of Sciences (CAS), with the goal of establishing a new class of PV devices that are able to promise a step-change in performance for both c-Si and thin film (e.g. a-Si:H) PV technologies. | £631,430 | 2011 - 2014 | |
Enhanced solar energy harvesting in dye sensitized solar cells using nano-phosphors and nano-structured optics | EPSRC & TSB | On a recently completed TSB programme, CONVERT (TSB ref. AE100D), two of the partners of the present consortium (the Wolfson Centre at Brunel University and Intrinsiq Materials Ltd.) developed long-life down-converting phosphors that, once proven by scaling up in demonstrators, will be used worldwide in coatings and on cells to transfer more of the sun’s energy into preferred PV frequencies. In this project we will scale up DSSCs to show the effect of augmenting the natural energy available and hence enhance energy output. In addition, we will harvest the light from a third of G24i’s current cell’s surface that is wasted and redirect the light to the active regions of the cell, thereby aiming to achieve performance gains of ca. 25 . This research is being carried out by Brunel University. | £390,996 | 2011 - 2014 | |
Amorphous and crystalline GaNAs alloys for solar energy conversion devices | EPSRC | The choice of material for the photoelectrochemical, (PEC) photoanode (photocathode) is crucial for efficient hydrogen production, with a need for corrosion-resistance for prolonged operation. The band gap of semiconductor materials used for photoanodes must be at least 2.0eV, but small enough to absorb most sunlight. In addition to choosing the correct band gap, the conduction and valence band edges must straddle the H+/H2 and O2/H2O redox potentials so that spontaneous water splitting can occur. Currently there is no material that fully satisfies these requirements. Gallium nitride (GaN) is an excellent candidate for this application since it has a band gap 3.4eV, high mechanical hardness and high chemical stability. The band gap of GaN can be adjusted and decreased due to strong negative bowing in the GaN-based solid solutions with group V elements. The group from Berkeley have theoretically predicted that GaNAs alloy with a band gap 2eV could be the ideal photoelectrode material. The Nottingham, Strathclyde and Berkeley groups have jointly investigated the growth and properties of GaN1-xAsx alloys at the N-rich end of the phase diagram during recent years. Our collaboration was strengthened by a 1 year EPSRC feasibility grant (EP/G007160/1), which showed that it is indeed possible to grow such structures by molecular beam epitaxy (MBE). We have succeeded in achieving GaN1-xAsx alloys over a large composition range by growing the films much below the normal GaN growth temperatures. We discovered that alloys with a high Arsenic (As) content, above 17 , are amorphous, but despite this fact the GaNAs energy gap decreases monotonically with increasing As content. Optical absorption measurements reveal a continuous gradual decrease of band gap from 3.4eV to 1.4eV with increasing As. Soft x-ray absorption spectroscopy (XAS) and soft x-ray emission spectroscopy (SXE) studies have shown that the conduction band moves down and valence band moves up as the As composition increases in amorphous GaNAs alloys. Our results indicate that the amorphous GaN1-xAsx alloys have short-range ordering that resembles random crystalline GaN1-xAsx alloys. These GaN1-xAsx alloys cover the whole composition range and can be used not only for photoanode applications in PEC cells for hydrogen production, but also have technological potential for many optical devices operating from the ultraviolet to the infra-red. | £416,206 | 2011 - 2014 | |
Interconnect Manufacturing Process for Thin Film Solar Cells (IMP) | TSB and EPSRC | This TSB/ EPSRC funded project “Interconnect Manufacturing Processes for thin film solar cells”, brings together a powerful consortium with the aim of developing a simplified interconnect technology for thin film PV involving laser scribing and fast inkjet backfill with the dielectric and conductive materials. This high value manufacturing process will substitute one system for the six separate machines currently used. This single step approach will dramatically change the way PV modules are manufactured reducing complexity and cost of production. The programme takes advantage of existing thin film PV deposition technology at Powervision Ltd and world class solar cell characterisation and testing facilities at CREST (Loughborough University). M-Solv, the lead partner, has expertise in advanced laser micromachining and inkjet applications and also has good routes to market, particularly in the Far East. | Not available | 2011 - 2014 | |
Development of Prototype High Efficiency Multi-Junction Organic Solar Cells | EPSRC and TSB | In this collaborative R&D project a consortia of industry and university groups will develop prototype Organic photovoltaics (OPV) cells using our patented multi-junction cell technology. Nano-structured organic and inorganic materials will be incorporated into multi-junction cells which will then be optimised to demonstrate high performance characteristics (efficiency and stability) as well as compatibility with low cost, large area fabrication. A key objective of this project will be to incorporate new transparent conducting electrodes into the multi-junction cell technology, thus eliminating the requirement for indium tin oxide (ITO) and enabling the new technology to overcome one of the key obstacles to low cost manufacture. This research is being carried out by the University of Warwick. | £1,088,162 | 2011 - 2014 | |
Scalable low-cost organic photovoltaic devices | EPSRC | This project carried out by The University of Bath focuses on three key challenges for the translation of these lab-scale efficiencies into, low cost, scalable photovoltaic device technologies. Specifically, the three aims of this project are: (i) development of indium and PEDOT -free transparent conducting electrodes which are compatible with high device-module efficiencies and cost effective scale up and (ii) development of new synthetic methods for the scale-up of high-performance organic semiconductors and (iii) the implementation of these materials into OPV modules fabricated employing processing methodologies compatible with high through put, low cost manufacture. To address these aims we have assembled a highly multidisciplinary team comprising academics and industries with world-leading expertise in inorganic oxide electrode film deposition, polymer synthesis, processing, thin-film printing, functional characterization, nano-morphology, device physics and manufacturing. This proposal builds directly on the substantial advances made in our Stage 1 Grand Challenge in nano-technology and Energy program funded by EPSRC, targeting the demonstration of a commercially viable production process for OPV devices with enhanced stability and reduced cost. | £272,003 | 2011 -2014 | |
Scalable, low-cost organic photovoltaic devices (SCALLOPS) | TSB and EPSRC | This project focuses on the key challenges for the translation of these lab-scale efficiencies into, low cost, scalable photovoltaic device technologies.

Semiconductor nano-crystals for solar cells: Tuning shape, size and interface effects | EPSRC | This project at UCL will be built on one of the major challenges in contemporary physical sciences, that is the efficient conversion of the Sun’s light into electricity in solar cells. By combining the experiences of two leading material simulation groups in the UK and China, we will provide an atomistic understanding of the processes that occur under the influence of light in technologically important semiconducting materials, especially the II-VI chalcogenide semiconductors. Our approach will be to exploit our complementary expertise in modelling the electronic properties of nano-structured and defective crystalline systems, which we will apply to novel solar cell architectures using inorganic nano-particles to absorb light - a highly topical area of interdisciplinary sciences at the heart of the stated research priorities of EPSRC. The primary focus of this project is on the simulation of real materials at length scales relevant to experimental analysis and photovoltaic device physics: bridging the gap between theory and experiment as well as the geographical divide between the UK and China. The project partners are Prof. Jingbo Li and Prof. Jian-Bai Xia from the Institute of Semiconductors, Chinese Academy of Sciences in Beijing, who are two world-leading experts in the simulation of semiconductor quantum dots. Together, we will address the fundamental physical processes occurring in a new class of nano-structure solar cells, where new electronic states introduced by the nano-structured materials can facilitate the utilisation of photons of sunlight that lie outside the range of traditional bulk heterojunction solar cells. In addition to providing the methodological advances required to describe these systems, we will address the optimal material combinations to enhance light to electricity conversion efficiencies in future solar cell devices. This project will utilise existing high performance computing infrastructures at both institutions, and all results will be directed into ongoing experimental work in both host countries. The successful outcome of the project promises substantial general impact in a key and highly relevant area of physical sciences, and the establishment of a strong material simulation collaboration between the UK and China in the fields of solar cells and computational materials science. | £408,699 | 2011 - 2014 | |
Nano-crystalline Water Splitting Photodiodes II: Device Engineering, Integration and Scale-up | TSB and EPSRC | In this collaborative R&D project at the University of Warwick, a consortium of industry and university groups will develop prototype OPV cells using our patented multi-junction cell technology.

A key objective of this project will be to incorporate new transparent conducting electrodes into the multi-junction cell technology, thus eliminating the requirement for indium tin oxide (ITO) and enabling the new technology to overcome one of the key obstacles to low cost manufacture. Prototype cells will be developed that demonstrate certified power conversion efficiencies of 8 , accelerated lifetimes equivalent to 3 years in the field, and active cell areas of 10 cm x 10 cm. | £291,848 (EPSRC funding) | 2011 - 2014 | |
Heterointerface control of organic semiconductor devices | EPSRC | Organic electronic materials are widely used in LEDs, transistors and, though less advanced, in solar cells. Organic semiconductor devices are generally divided into two classes: those made by vacuum deposition of so-called ‘small molecules’ and those made by solution-processing of film-forming materials (typically polymers). The UK community, following some of the early work at Cambridge has tended to concentrate on the latter class of materials. The rationale for this is two-fold. Firstly, in terms of translation to large-scale manufacture, direct low-temperature solution processing of active semiconductors is very attractive for low-cost processing, particularly where patterning can be carried out by direct printing (ink-jet printing has been developed, for example, for deposition of red-, green- and blue-emitting materials in full colour displays). Secondly, solution processing presents challenges and opportunities for the formation of useful device structures. In some respects it is awkward - it is generally difficult to assemble multiple layers of organic semiconductor to make conventional laminar hetero-structures because solvents are typically not sufficiently specific to allow successive layer depositions without disturbing lower layers - but in other respects, there are real opportunities to generate architectures that would be very difficult to make conventionally. | £6,693,636 | 2009 - 2014 | |
Carrier lifetime measurement at grain boundaries in thin-film solar cells | EPSRC | In this project we will use state-of-the-art measurements of carrier lifetimes at individual grain boundaries to explore the fundamental mechanism(s) behind chlorine activation. The carrier lifetime is an important parameter specifying the electrical activity of a given grain boundary and its effect on device operation. In order to carry out such measurements a high spatial resolution (few nano-metres) must be combined with excellent temporal resolution (a few picoseconds) the technical demands for which have only recently been overcome. We will carry out the very first measurements of grain boundary carrier lifetimes in CdTe thin-film solar cells using the new Attolight scanning electron microscope recently installed at EPFL, Switzerland. This is the only scientific instrument of its kind in the world capable of carrying out such analyses. We will also explore the relative effectiveness of different chlorine activation routes (i.e. standard activation using solid CdCl2 and gas activation methods) for passivating grain boundaries. This has important long term commercial benefits such as the production of efficient CdTe thin-film solar cells as well as reducing the environmental impact of the chlorine activation process. This research is being carried out by the University of Liverpool. | £25,425 | 2012 - 2013 | |
Engineered bulk heterojunction inorganic:organic hybrid photovoltaics | EPSRC | Inorganic-organic hybrid photovoltaic (h-PV) devices are a realistic prospect for the long-term development of entirely solution processable, scalable devices on rigid and flexible substrates. The pairing of a metal oxide (TiO2, ZnO) with a conjugated polymer to form a hybrid device is an attractive combination of materials. For example, ZnO provides efficient electron mobility, effective light-scattering, is of low cost and can be formed in a wide variety of (nano-) structures from aqueous solution. The absorbing, hole-transporting conjugated polymers, such as poly(3-hexylthiphene)(P3HT), support a wide variety of processing routes and exhibit some of the best charge transport of all organic semiconductors. However progress made towards realising such h-PV technologies has been slow. Reported power conversion efficiency (PCE) values are typically < 1 , with some more recent publications reporting 2 . This compares with reported efficiencies of >8 for commercial organic-PVs. The nano-structured devices that will be prepared in this program will provide controlled bicontinuous networks for charge, and importantly will allow control of the polymer morphology - a parameter that has received little attention in h-PVs - although it is known to strongly influence exciton generation, free carrier transport and light absorption. This unique combination of materials and processing strategies presents an exciting opportunity for the development of h-PV devices that can overcome the current performance limitations by allowing control of the structural and morphological properties of the device not possible with other material combinations or processing techniques. This research is being carried out by the Imperial College, London. | £99,908 | 2012 - 2013 | |
Stability and Performance of Photovoltaics | EPSRC | Definition of the performance of photovoltaics is normally reduced to the efficiency alone. However, this number contains no indication of key issues such as system component reliability, module stability or appropriate balance of system design, all of which play a crucial role in determining the performance in terms of usability. This UK-India collaboration will tackle some of the main challenges in developing cost-effective, efficient and stable solar systems. This project is being carried out by Loughborough University. | £2.4m | 2010 2013 | |
Cheap Solar Electricity The Essential Fuel of the 21st Century | EPSRC | Through this project, our team of scientists at Edinburgh University and beyond will collaborate with a number of public engagement experts to enable school students and the public of all ages and backgrounds to explore, discuss and reflect upon the issues related to innovation in low-cost solar energy technologies and its pressing need for the future of our planet. This proposal brings together the expertise and scientific entrepreneurship provided by the scientists within the innovative EPSRC Supergen consortium on Excitonic Solar Cells, with the public engagement expertise of The UK Association for Science and Discovery Centres, The Scottish Schools Equipment Research Centre (SSERC), The science media centre, CLEAPSS and the National STEM centre. | £152,343 | 2010 - 2013 | |
Probing and enhancing charge generation and transport in solid-state dye-sensitized solar cells | EPSRC | Photovoltaic devices that harvest the energy provided by the sun have great potential as clean, renewable sources of electricity. Despite this, uptake of photovoltaic energy generation has not been strong, largely because devices based on many current technologies are still too expensive. One promising alternative is given by organic-inorganic hybrid cells based on dye-sensitised metal oxide mesoporous electrodes, which are cheaper to produce and have reached power conversion efficiencies of over 11 . However, there remain concerns about the incorporated redox active liquid electrolyte, presenting the possibility of toxic, corrosive chemicals leakage. Recent research into replacing the liquid electrolyte with a solid-state hole-transporter has yielded cells with up to 5 power conversion efficiency. The University of Oxford propose a structured research programme that will lead to increases in the power conversion efficiencies of all-solid-state dye-sensitized solar cells (SDSCs) towards that of their electrolyte-containing counterparts. In particular, we will use a new approach in order to establish criteria for optimization of essential parameters such as the nano-scale morphology of the electrodes, the charge-mobility for the hole-transporter and the energetic level arrangement at the interface. The study will combine device measurements with a range of time-resolved spectroscopic investigations to deduce how each change to the system affects individual photophysical processes (such as photo-excited electron transfer) in the material, and how this translates into efficiency of device operation. Work will be based on a careful selection of material components that allow tuning of only one particular property at a time. This combined new approach will not only allow significant improvements to be made to specific SDSC designs, but also deliver a more general framework for the exact requirements of successful optimization approaches. | £739,361 | 2010 - 2013 | |
Artificial Photosynthesis: Solar Fuels | EPSRC | The development of scalable, efficient and low intensity-tolerant solar energy harvesting systems represents one of the greatest scientific challenges today. In this research proposal we propose to explore a bold and innovative approach that uses solar energy to both generate energy and fix carbon dioxide in one step, to produce a type of solar fuel cell which would yield methanol or similar feedstock (this is the long term 10 year aim). This is an extremely challenging problem and in this study we will bring to together researchers in Chemistry and Electrical Engineering in Glasgow, with those in existing Bio-energy research (Bacterial Photosynthesis, Plant Molecular Biology) along with the key international groups in this area from the USA, Japan, and Germany, to explore the idea of transferring concepts from natural photosynthesis to solid state devices. In this research we will learn from Photosynthesis how to arrange light harvesting/reaction centre units on a surface in an immobilised environment to assemble highly efficient and broad spectrum light harvesting devices using inorganic/organic chemistry approaches. Therefore by combining research from Chemistry (Model systems, supramolecular chemistry, and photoactive units and metalloenzyme models) with Electrical Engineering (Surface patterning, lithography, and surface structure manipulation) and Molecular Biology (Structural biology, biological electron transfer, and membrane bound proteins) we will develop a major and long term interdisciplinary research program with this grand aim. This research is being carried out by the University of Glasgow. | £1,559,914 | 2009 - 2013 | |
Combinatorial CVD | EPSRC | This is an application for a Platform for baseline funding to support the joint Carmalt/Parkin research group. Parkin and Carmalt have collaborated extensively in the area of Chemical Vapour Deposition (CVD). Carmalt has focussed on the synthesis of molecular precursors for use in CVD, whereas Parkin has concentrated on the CVD growth and functional characterisation of thin films from these and other precursors. In the course of this research by UCL, they have, unusually for CVD, discovered a wide number of new phases especially metal nitride, oxide, sulfide and selenide materials that had proven due to kinetic reasons and precursor design, unobtainable by conventional solid-state synthesis. They have also determined how to control preferred growth and orientation of crystallites grown by CVD. This has enabled them to grow materials with improved functional properties for a variety of applications from gas-sensors, through ultraphobic, super-hydrophilic surfaces to thermochromic and self-cleaning films. The pinnacle of this work, especially for new phase determination has been their use of combinatorial CVD for the synthesis of new materials. Combinatorial CVD is currently the major focus of the Carmalt and Parkin joint group and is a significant component of all of their current EPSRC funding. | £814,511 | 2009 - 2013 | |
Advanced Bio-Photovoltaic Devices for Solar Energy Conversion | EPSRC | Harvesting a large proportion of solar energy, in a cheap, efficient manner, poses many difficult technical challenges. At present, silicon based solar PV cells are the method of choice, but these devices tend to be very expensive to manufacture, since they contain highly purified, semi-conductive materials. In this application we propose to harness the photochemical reactions associated with photosynthesis, a fundamental biological process, to convert sunlight into a usable form of energy by means of a biological photovoltaic panel. Using a multidisciplinary consortium of groups based in Plant Science, Biochemistry, Genetics, Engineering and Chemistry we intend to develop, test and optimise biological photovoltaics for the production of hydrogen and/or electricity. In this application, we propose to separate the processes of oxygen evolution and hydrogen production in a semi-biological photovoltaic device using intact photosynthetic cells, in which protein complexes are intrinsically more stable, and which furthermore have mechanisms for self-repair. The device will be composed of two chambers, or half-cells, with oxygen evolution confined to one chamber and hydrogen production to the other. In addition, the approach can be used to produce a DC electrical current, in a manner analogous to standard silicon based photovoltaic panels. This research is being carried out by the University of Cambridge. | £1,137,893 | 2009 - 2013 | |
Femtosecond Optical Probes of Mesoscopic Materials for Photovoltaics | EPSRC | There is growing evidence that our increasing consumption of fossil fuels is leading to a change in climate. Such predictions have brought new urgency to the development of clean, renewable sources of energy that will permit the current level of world economic growth to continue without damage to our ecosystem. Photovoltaic cells based on organic or organic/inorganic hybrid materials have shown rapid improvements over the past decade, comparing favourably with existing inorganic semiconductor technology on energy, scalability and cost associated with manufacture. The most promising materials for organic or hybrid photovoltaics are based on blends of two components at whose interface light-generated excitations dissociate into charges contributing to a photocurrent. Blend morphology on the meso-scale plays a crucial role in these systems, with efficient photovoltaic operation requiring both large interfacial area and existence of carrier percolation paths to the electrodes. The proposed work will establish how both aims can be achieved, using a powerful new combination of non-contact femtosecond time-resolved techniques to examine a range of novel mesoscopic blends. This methodology will allow the simultaneous examination of exciton diffusion and dissociation, charge-carrier generation, recombination and conductivity, providing direct clues to the optimisation of materials for photovoltaics. Collaborations with researchers working on making photovoltaic devices will ensure that knowledge gained from these non-contact material probes will directly feed into enhancing device performance. This combined approach will allow the UK’s exceptionally high expertise in the area of organic electronics to contribute effectively to its current goal of reducing harmful greenhouse gas emission. This research is being carried out by the University of Oxford. | £800,425 | 2009 - 2013 | |
Materials World Network: Nano-structured materials from nano-particle- and block copolymer assemblies for nano-photonics and optoelectronics | EPSRC | The proposed research includes synthesis of all necessary organic/polymer and inorganic components, characterization of assembly structures using various scattering, optical and electron microscopy techniques, as well as thorough investigations of their optical properties including simulation and modelling efforts, and work towards major novel optics in the form of sub-wavelength imaging, highly sensitive hot-spot arrays over macroscopic dimensions for sensing, and sub-wavelength waveguiding. While the main focus of our proposed work lies on non-magnetic materials and the assessment of linear optical properties of the fabricated compounds, a crucial point is that we are aiming at synthesis approaches that can be generalized over a wider class of materials systems. A final thrust of the program addresses a particularly topical exploitation area, where we will integrate specific plasmonic structures into hybrid solar cells and characterize and optimize plasmon enhanced photo-generation of charges and subsequent solar cell efficiency. If successful this will lead to a new generation, or class of photovolatics, namely plasmonic solar cells. This research is being carried out by Imperial College London. | £530,211 | 2009 - 2013 | |
SUPERGEN Excitonic Solar Cell Consortium - MAIN CORE | EPSRC | Excitonic Solar Cells (ESCs) are a class of non-conventional solar cells, based on organic and nano-structured materials, in which the charge carriers are generated and simultaneously separated across a heterointerface. They include dye-sensitized nano-crystalline cells, organic cells and hybrid organic-inorganic cells, and in all cases cell fabrication can be achieved using low cost, large area deposition methods on both rigid and flexible substrates. Consequently, ESCs offer genuine medium to long term prospects for reducing the cost of PV below the commercially important threshold of $1 per watt peak. To date work on all types of ESC has been largely restricted to basic studies in academic and national research laboratories, with particular emphasis on improving device understanding and cell efficiency, which are 11 for state of the art dye cells, and much lower for the less well developed organic (4-5 ) and hybrid cells (2-3 ). However, progress in all types of ESC has undoubtedly been impressive in recent years, with research activity growing rapidly throughout the world. Major improvements in performance have been demonstrated in all cell types with the SUPERGEN Consortium at the forefront of much of this progress. This consortium is led by Warwick University with partners, Imperial College London, University of Cambridge, University of Bristol, University of Edinburgh, University of Bath, University of Oxford, Loughborough University and Heriot-Watt University. | £3,314,933 | 2009 - 2013 | |
Theory of dye sensitized solar cells | EPSRC | Only a small fraction of the world energy usage (less than 0.05 in 2004) derives from solar cells because of the high cost of the current technology based on crystalline silicon. Dye Sensitized Solar Cells (DSSC or Gratzel cells) are one of the major alternatives to silicon photovoltaics and the subject of the proposed investigation. DSSC are relatively complex systems including a nano-crystalline titanium dioxide (TiO2) semiconductor, a dye adsorbed on it, a solution containing an electrolyte that can be reduced and oxidized and a transparent electrode. The efficiency in the conversion of light into electricity achievable in mass produced DSSC is around 7 , while a desirable target efficiency of 15 (or larger) would make this technology suitable for large scale electricity production. Current improvements of the DSSC rely on the development of new dyes and new electrolytes. There are currently no predictive theories that allow the systematic improvement of DSSC and the efficiency improvement is largely based on chemical intuition and systematic search. The aim of the proposed research is to develop a methodology to compute and predict the elementary rates of all microscopic (charge transfer) processes taking place in DSSC. The control and understanding of these elementary processes are the basis for the rational improvement of cell efficiency. The theoretical description of DSSC requires a cross-disciplinary approach involving elements of solid state physics, electrochemistry and quantum dynamics. This research is being carried out by the University of Warwick. | £330,219 | 2009 - 2013 | |
Nano-structured metafilms: a new paradigm for photonics | EPSRC | The proposed research at the University of Southampton introduces a special type of metamaterials, namely planar metamaterials (or metafilms), for practical photonic applications. As a result, a whole new class of extremely compact (low-dimensional) photonic devices that replace the existing bulk optical components (such as spectral filters, polarizers, waveplates, beam splitters etc.) is envisaged. But more importantly artificial planar media allows achieving exotic photonic functionalities (e.g. optical superconductor, asymmetric transmission) that are hardly possible with the use of conventional bulk optical materials. Moreover, the research aims to add a new dimension to the concept of planar metamaterials, and therefore dramatically expand the range of available photonic functionalities, by combining electronic/molecular response of media and metamaterial resonances due to structuring. | £826,439 | 2008 - 2013 | |
Nitride Photovoltaic Materials for Full Spectrum Utilization | EPSRC | Solar energy has to be converted into a useable form at reasonably low cost. Indeed, in the UK, recent increases in renewable energy generation have mostly relied upon increased use of wind power due to the relatively high cost of solar power. One of the most promising approaches to reducing the cost of solar power, is to use small-area high efficiency cells with light concentrated on them by low cost, large-area plastic lenses. The highest efficiency solar cells to date consist of three junction III-V semiconductor devices containing both arsenides and phosphides. The failure of the band gaps of these materials to match the wavelength range of the solar spectrum limits the maximum efficiency obtainable. This research is being carried out at the University of Liverpool. | £491,436 | 2012 2014 | |
Ageing of Printable polymer Cells | EPSRC | In this proposal we address the most important remaining issue, namely understanding and enhancing the lifetime of polymer solar cells. To do this we will combine advanced photophysical, morphological and chemical analysis of solar cells before, during and after operation to gain new insight into the factors controlling degradation of such cells. This will provide a solid foundation for developing strategies for extending the solar cell lifetime in the later part of the project.The operation of polymer solar cells depends critically on the nano-metre scale arrangement of the materials, so we will use sophisticated electron tomography techniques to study the nano-scale morphology and how it changes with device operation. This will be complemented by optical and electronic measurements performed in-situ on operating solar cells. A further innovation will be to make nano-scale perforation of an encapsulation layer and combine it with electron beam techniques to study local degradation with nano-metre resolution. This research is being carried out by the University of St Andrews. | £589,517 | 2011 - 2013 | |
EXPLORER; Excitonic Polymer Organic Devices for Energy | EPSRC | Durham University propose three adventurous, cross-disciplinary projects within the area of energy research. The past decade has seen an upsurge in interest in the field of organic electronics. Devices such as light-emitting displays and chemical and physical sensors are already on the market - and probably in your home and in your pocket - while others, such as solar cells are developing fast. The motivation is the reduced cost, ease of manufacture, large-area capability and the enhanced efficiency which is possible using these new technologies. However, a lot more research is still needed. This study will unite: (i) the synthesis of new materials, (ii) detailed spectroscopic characterisation (iii) device fabrication and measurements of performance, and (iv) theoretical calculations. | £201,616 | 2011 - 2012 | |
Elimination of Efficiency Degradation Mechanisms in Silicon Photovoltaic Solar Cells | EPSRC | This research proposal aims to eliminate the degradation process by removing the reaction path from the silicon prior to the formation of the recombination centre. An essential pre-requisite to this is to achieve a detailed understanding of the defect centres and their formation. We have previously studied the oxygen dimers which are currently thought to be the precursors of the recombination centre. These can be detected using optical absorption measurements, ideally at low temperatures ( 10K). Preliminary work indicates that it should be possible to develop treatments of the silicon material which reduce the concentration of the dimers to a negligible level in the finished cell and, because the dimers do not form at normal operating temperatures, so eliminate the formation of the defect. It would be quite feasible using this approach to maintain the concentration of interstitial oxygen which provides mechanical strength to the silicon with consequent yield and cost benefits. In this work the recombination centre will be studied using minority carrier Laplace Deep Level Spectroscopy and its structure determined by the application of uniaxial stress. The reaction of the oxygen dimer will be studied as the recombination centre forms, in real time, using optical absorption techniques. The work will be done in collaboration with MEMC who are one of the leading manufacturer of solar silicon, the Institut f r Solarenergieforschung Hameln/Emmerthal (ISFH) in Germany who have undertaken much experimental work recently on solar cell degradation and the University of Aveiro in Portugal who will collaborate on theoretical calculations to support the Manchester work. | £268,035 | 2010 - 2012 | |
Materials World Network: Hybrid photoconductors for high-efficiency photovoltaic cells | EPSRC | The research carried out by Imperial College London is highly multidisciplinary and combines experimental and theoretical approaches. The fundamental science and engineering questions we are going to study in this program include: (i) the development of automated microfluidic reactors for the synthesis of various II-VI and III-V nano-particles that emit in the visible or NIR; (ii) the influence of conjugated surfactants, including conjugated self assembled monolayers (SAMs), on energy and/or charge transfer processes from the host semiconductor; (iii) the effects of nano-particle surface traps and chemical bonding interactions introduced by the surfactant capping layers on the operation of hybrid organic/inorganic nano-particle solar cells and their stability. Our research plan is comprised of the following main tasks: i) Synthesis of high quality defect-free nano-particles of controllable size and chemical composition by the use of microfluidic reactors, including in-line and off-line characterization of the nano-particle quality; ii) Capping of the nano-particles and characterization of the capping layer and its effect on the charge and/or energy transfer from the host; iii) Modeling, fabrication, and characterization of bulk heterojunction hybrid organic/inorganic nano-particle semiconductor thin-film photovoltaic devices. Tasks i) and ii) will be lead by Imperial College while task iii) will be lead by Georgia Tech. | Not available | 2009 - 2012 | |
A novel Design and analysis of 3D Building Integrated Concentrating Enhanced Photovoltaic Thermal System: BICEPT | EPSRC | This project will develop a non-tracking concentrating photovoltaic/thermal (CPV/T) system with optimised performance, which will be suitable for building facade/roof integration. As no tracking is required it is possible the cost of this system to reduce by two-fold, which makes more attractive for building integration. This will be undertaken through a new three dimensional design of a compound elliptical-hyperboloid concentrator of concentration ratios of 6.25 through a set of computation simulations together with controlled and outdoor tests. This design will enhance the optical efficiency of the concentrator unit and hence improve the overall electrical and thermal efficiency of the concentrating PV/T system. A prototype system will be made and indoor controlled characterisation will be undertaken at the HWU. Based on the process refinement one kWp system will be manufactured to characterise at outdoors test conditions. In addition, an integrated Optical, Heat transfer and Electrical (OHE) model will examine the PV/T system to optimise its performance. | £178,444 | 2009 - 2012 | |
Science Bridge Award USA: Harnessing Materials for Energy | EPSRC | This Science Bridge proposal builds upon the existing collaboration between the University of Cambridge and the University of California at Santa Barbara to perform the research required to bring existing research through to prototype products and devices in the field of energy-related materials. The proposal has five key themes: organic and inorganic solar cells; light emitting diodes (LEDs) based on gallium nitride (GaN); phosphors for solid-state lighting; organic LEDs (OLEDs); the low-cost integration of LEDs and OLEDs onto printed circuit boards; and ultralight materials and structures. We propose two approaches to make solar energy more viable. First, we propose to develop moderate-efficiency (about 15 ) organic solar cells at extremely low-cost. UCSB will concentrate on developing more efficient cells and Cambridge will address low-cost manufacturing methods. This requires significant advances in printing methods for organic film deposition. The other approach to solar cells we will pursue is high-efficiency inorganic multilayer solar cells. The basic idea is that by stacking layers in the order of their bandgap, with the layer with the largest bandgap at the top, light is converted into electricity in the most efficient way. | £1,447,635 | 2009 - 2012 | |
Dilute Nitride Type II Quantum Dot Materials for Solar Cells based on GaAs - Collaborative Research in Energy with South Africa | EPSRC | The development of efficient, affordable solar cells for clean energy production is a major global challenge and in this proposal we are seeking to achieve a breakthrough in the fabrication of novel quantum dot materials capable of substantially improving the performance of III-V solar cells based on GaAs. Lancaster University propose a close collaborative project with Nelson Mandela Metropolitan University in South Africa, who have complementary expertise in photovoltaic cells, to develop and characterize hitherto unexplored GaSbN/GaNAs type-II quantum dot materials. These strain-compensated, dilute-nitride quantum dots will be implemented within the active region of prototype GaAs based solar cells to significantly extend the spectral response and improve the efficiency. This would lead to a new generation of solar cells for clean electricity generation. Feedback from device studies will provide valuable insight into the photovoltaic properties of these unique nano-structures, further aiding material optimization. The quantum dot materials that we shall develop here could either be used to increase efficiency in single junction cells, or could be incorporated into existing multi-junction cells to replace expensive Ge substrates, reduce cost and significantly increase performance. There are clear opportunities for uptake of the technology both within South Africa and the UK. | £401,156 | 2009 - 2012 | |
Structure-Property-Performance Relationships for Organic Bulk Heterojunction Solar Cells | EPSRC | Organic semiconductors combine the semiconductor properties traditionally associated with inorganic materials with the more desirable properties of plastics such as low cost, flexibility and ease of processing and patterning. Moreover, the organic syntheses of these materials allow for great flexibility in the tuning of their electronic and optical properties. By combining these properties, organic semiconductors such as conjugated polymers and small molecules have been demonstrated as the active layer in a wide range of optical and electronic devices including photovoltaic solar cells. The leading design of organic solar cells is based on the bulk heterojunction, in which organic blends comprising an electron donating component (usually a conjugated polymer) and an electron accepting component (such as a fullerene derivative or a conjugated polymer) that are dissolved in the same solvent and then spin-coated from the solution to form a thin film, sandwiched between two different electrodes. Recent developments in materials and device fabrication processes are leading to rapid improvements in performance of these devices. For example, solar conversion efficiencies up to 5-6 were reported for solution-processed organic solar cells. Despite their significantly improved device performance, a number of scientific challenges remain to more fully understand, quantify, and predict the behaviour of the organic bulk heterojunction solar cells. This research is being carried out by the Imperial College London. | £288,685 | 2009 - 2012 | |
Enhanced solar light harvesting and charge transport in dye-sensitized solar cells | EPSRC | Dye-sensitized solar cells are moderately efficient with verified solar-to-electrical power conversion efficiencies of over 12 reported. However, even in the state-of-the-art systems only a fraction of the incident sun light is absorbed, implying substantial scope for improvement. Here we develop both state-of-the-art liquid electrolyte based DSCs and contemporary solid-state hybrid DSCs with the target being to considerably enhance the light capture and adsorption in these devices and also significantly improve the charge transport characteristics. Routes to both improve the photonic structure of the solar cells, create improved semiconducting oxide electrodes for enhanced charge transport and collection and develop and optimise new sensitizers for these systems shall be undertaken. This research is being carried out by the University of Oxford. | £101,895 | 2009 - 2012 | |
Low cost integrated PV in double glazed windows using CdTe bifacial solar cells | EPSRC and TSB | The aim of this project is to apply a thin film photovoltaic layer on to the inside face of a double glazed unit with the potential to supply up to 50W of power from the average window. Initial studies show that this is possible using highly efficient CdTe absorber along with TCO contacts. Further design work involving all the partners is required to integrate this with coatings for infra-red reflection. The bifacial CdTe solar cell technology allows the opportunity for thin film based solar cells to be used in building integrated PV (BIPV). This research is being carried out by Loughborough University. | £245,638 | 2009 - 2012 | |
SUPERGEN - PV Materials for the 21st Century | EPSRC | PV-21 is the UK’s inorganic solar photovoltaic (PV) research programme. This proposal is for a renewal for the second four year cycle. The Consortium has sharpened its focus on the science that will deliver our medium to long term goal of “making a major contribution to achieving competitive PV solar energy”. They had put in place lab-scale facilities for making three main types of solar cells based on thin film absorbers - copper indium diselenide, cadmium telluride and ultra thin silicon. To reduce costs, they will concentrate on critical materials and PV device issues. The team comprises nine universities - Durham University, University of Edinburgh, Imperial College, Northumbria University, University of Southampton, Glyndŵr University, University of Bath, Southbank University and Cranfield University along with seven industrial partners. PV-21 is also plays an important role in skills development, with nine PhD students due to be trained in the first cohort. | £6.2m plus £1.86m | 2008 2012 | |
High stability and high efficiency printable photovoltaics (OPV) for large-scale energy production | EPSRC | The depletion of oil reserves, spiralling fuel costs, concerns about the security of global energy supplies, and belated worldwide recognition of fossil-fuel induced climate change have sparked an urgent and unprecedented demand for sustainable energy sources. Amongst all of these sources solar photovoltaic (PV) energy stands out as the only one with sufficient theoretical capacity to meet global electricity needs, but high costs of silicon based PV prohibit widespread take-up. In this programme, we focus on the development of organic photovoltaics (OPV) as a low cost technology with the potential to displace conventional power sources. The proposed programme links Imperial College London with four leading Chinese institutions, building on ICL’s strengths in the physics and application of molecular electronic materials and devices and on our partners’ strengths in speciality materials development and scale-up. A collaborative programme between the UK and China in this area is particularly timely, given the pressing need for alternative power sources that are capable of meeting the rapid development rate and large energy demand of China. Our proposal focuses on solution-processable organic molecules and polymers which share many of the chemical, structural and rheological properties of the inks used in conventional printing and which are amenable to large-scale production through the existing printing and coating industries. This research is being carried out by Imperial College, London. | £864,655 | 2008 - 2013 | |
Thermal Conductivity Enhancement of High-Temperature Thermal Energy Stores For Use with Solar Power Plants | EPSRC | Thermal energy storage is of critical importance in many engineering applications. The demand for CO2 reduction to curb global warming considerably increases the interest in utilizing renewable energy sources, especially solar energy. Due to the discrepancy between solar energy supply and energy demand, a thermal energy storage device has to be used. Thermal energy storage (TES) plays a vital role in solar energy applications in areas such as energy efficient buildings and solar power plants, and therefore, it has received significant attention. Thermal energy storage techniques can be classified as sensible heat storage and latent heat storage. Latent heat storage is particularly attractive, since it provides a high energy storage density and can store the energy as the latent heat of fusion at a constant temperature (phase change temperature of the corresponding PCMs). Although extensive investigations on low temperature latent heat storages mainly used for buildings have been conducted, very limited investigations on high temperature latent heat storages have been carried out for solar power plants. This research is being carried out by the University of Warwick. | £690,060 | 2008 - 2013 | |
Self-organized nano-structures in hybrid solar cells | EPSRC | Traditional mainstream inorganic semiconductor technology has been remarkably successful. However, standard fabrication techniques of microelectronic devices and components rely on a layer-by-layer assembly process and fall short of delivering three dimensional control of device architecture. Naturally-occurring complex systems utilize self-organising three dimensional architectures to deliver functionality beyond the properties of the individual components. To generate highly structured inorganic materials nature usually employs organic templates. Coordinating between inorganic chemistry, organic chemistry, material science and semiconductor physics is one of the opportunities within nano-technology. This area of multidisciplinary research provides the tools to fabricate three dimensional architectures which promise to deliver novel functionality to material composites. This research is being carried out by the University of Oxford. | £446,685 | 2008 - 2012 | |
Carbon Dioxide and Alkanes as Electron- sink and Source in a Solar Nano-cell: towards Tandem Photosynthesis of Carbon Monoxide and Methanol | EPSRC | The vision is to create a solar nano-device which will drive the coupled photo-conversion of methane and carbon dioxide into methanol and carbon monoxide respectively. This challenging target differs fundamentally from the familiar one of splitting water into hydrogen and oxygen. Our target offers products both on the oxidation and the reduction sides that are significant fuels or feedstocks. The photocatalytic reduction of CO2 and oxidation of alkanes represent long-standing goals of great complexity, but we base our concepts on well-established principles. The goals are broken down into individual components, each of which is highly challenging within its own right and delivery of each would constitute a major breakthrough. The challenges will be met by a team of scientists, integrated across the four centres of Manchester, Nottingham, York and Norwich, who lead teams with expertise in photophysics, nano-science, photochemistry, electrochemistry and synthesis. | £363,179 | 2008 2012 | |
Plastic UV Radiation Protection Operating by Stokes Emission (PURPOSE PROJECT) | EPSRC | This project at Brunel University aims to develop novel energy harvesting products for a wide range of applications. This will be achieved by enhancing the properties of polymer composites; more efficient use of solar/thermal energy, longer life and recyclability. These improvements stem from the use of novel inorganic phosphor particles downconverting solar UV light to other parts of the electomagnetic spectrum. With the incorporation of low cost novel phosphors, the new composite materials will have more efficient UV protection (giving longer life and enhanced recyclability), provide innovative thermal heating for climate control (in both car and domestic interiors), and give enhanced plant growth (by converting light to increase the intensity of the wavelengths of light used in photosynthesis). In summary, this generic technology has the ability to deliver significant energy benefits across a wide range of applications. | £461,183 | 2008 - 2012 | |
New and Renewable Solar Routes to Hydrogen Energy | EPSRC | The UK, together with the international community, is acutely aware of the problems arising from the unsustainable use of fossil fuels, and is increasingly focusing on the development of zero-carbon emission fuels, particularly hydrogen, using renewable energy sources. Of the renewable energy sources under consideration, solar energy is the most abundant and, if harvested efficiently, is capable of meeting global energy needs for the foreseeable future. It is estimated that solar power incident on the earth is 178,000 TW, approximately 13,500 times greater than the total global power demand (or burn rate) in 2000 (13 TW) and 6400 times greater than recent forecasts of the power demand for 2020 (28 TW). Much solar energy research is focused on its direct conversion to electricity in photovoltaic devices, or on its direct conversion to heat in solar thermal devices. A major barrier to all these’conventional’ routes is their prohibitive cost. Here, we propose to exploit low temperature natural biological and photocatalytic processes to develop alternative, and cost effective, methods for harvesting solar energy to produce renewable hydrogen fuels directly, and to explore how these could be embedded within novel, integrated energy production systems, incorporating fuel cell and hydrogen storage technology. The successful scale-up of these solar energy-driven renewable hydrogen generation processes would transform the supply of carbon-less fuel and make an enormous impact on the viability of hydrogen as an energy carrier. It will convert the potential to produce hydrogen in a carbon-free, renewable way into a process reality, and is an essential step on the route to fully exploiting fuel cell technology. It will position the UK as a world leader in one of the very few solutions to a truly sustainable energy future. As such, the impact is wide ranging, scientifically, technologically and commercially. This research is being carried out by Imperial College. | £4,106,687 | 2007 - 2012 | |
Three-dimensional nano-shere templating: A novel method for the preparation of nano-structured photovoltaics | EPSRC | More recently organic PVs which consist of organic semiconducting materials have been prepared, which typically are inefficient (<5 conversion efficiency) but are economically attractive. Light absorption in photovoltaic devices leads to the creation of electronically excited molecular states (excitons). Excitons can travel for a few tens of nano-metres and if an interface is reached they will dissociate into an electron and hole, creating current. If an interface is not reached the exciton and current will be lost. The short exciton diffusion length is the principle reason for poor conversion efficiency in organic PVs. The purpose of this project is to significantly increase the efficiency of photovoltaic devices by engineering and optimising architectures and interfaces in PVs. A three-dimensional templating method will be used to produce nano-structured, interconnected structures, which will overcome material limitations and present a viable route for the formation of low cost and efficient PVs. In addition to being economically attractive the project will allow for the first time a fundamental study of the relationships between the structure, composition and conversion efficiency in these exciting materials to be conducted. This research is being carried out by Imperial College London. | Not available | 2007 - 2012 | |
Advancing the efficiency and production potential of Excitonic Solar Cells (APEX) | EPSRC | This project is centred on the development of the materials, device structures, materials processing and PV-panel engineering of excitonic solar cells (ESCs). These have the potential to greatly reduce both materials and also manufacturing costs where the materials, such as organic semiconductors, dyes and metal oxides, can be processed onto low-cost flexible substrates at ambient temperature through direct printing techniques. A major cost reduction is expected to lie in much-reduced capital investment in large scale manufacturing plant in comparison with conventional high vacuum, high temperatures semiconductor processing. There are extensive research programs in the UK and India developing these devices with the objective of the increase in PV efficiency through improved understanding of the fundamental processes occurring in these optoelectronic composites. However, there has been less activity in the UK and India on establishing from this science base a scalable, commercially viable processing protocol for excitonic solar cells. The scope of this UK-India call enables research and development to be undertaken which can pull together the set of activities to enable manufacturing application, and this extends beyond the usual scope of funding schemes accessible to the investigators. This project tackles the challenge to create cost-effective excitonic solar cells through three components: new material synthesis of lower cost materials; processing and development of device (nano-)architectures compatible with low process costs; and the scale up towards prototypes which can replicate solar cell performance achieved in the research phase. This project was carried out by Loughborough University, Heriot-Watt University, Imperial College London, University of Oxford, and University of Cambridge. | £2,039,039 | 2011 - 2013 | |
High efficiency silicon solar cells with PECVD dielectric rear surface passivation - HIGHPOINT | EPSRC | The project aim is to develop an industrial production process for a new design of monocrystalline silicon solar cells with an efficiency above 20 on a cell area of 150 cm2 which can be manufactured cost effectively in high volume. The solar cell structure will comprise the high efficiency front contact laser grooved buried contact process together with state of the art plasma enhanced chemical vapour deposition (PECVD) of low temperature dielectric films in the amorphous silicon dioxide/carbide/nitride family producing a pacified rear surface. The metal contacts will be formed by a self-aligning plating process. The improvements will be demonstrated at an industrial scale and the potential for a 20 reduction in cost at the PV system level will be verified. This research was carried out by HWU. | £383,195 | 2008 - 2011 | |
Manufacturable nano-scale architectures for heterojunction solar cells | EPSRC | This project at the University of Cambridge will produce manufacturable nano-scale architectures for heterojunction solar cells. Though routed strongly within ‘science’, the objectives are to achieve engineering solutions to allow the breakthrough needed in this field (target efficiency 10 ). Excitonic solar cells based on molecular semiconductors require the presence of a heterojunction between electron and hole-accepting semiconductors in order to separate charges from photogenerated excitons. Large heterojunction interfacial areas are required if all photogenerated excitons are to reach the heterojunction before decaying, and this requires a complex nano-scale architecture. Current methods to achieve this nano-structure and limited and solar cell performance of such devices has stalled. We propose therefore to develop generic routes to separate the control of the nano-scale morphology from the selection of the donor and acceptor semiconductors. This will represent a critical advance in allowing a stable process window, and should allow improved photovoltaic performance through better morphology control and the ability to use semiconductors better matched to the solar spectrum. These routes will be compatible with low temperature processing (this is critical for low-cost manufacturing). The general principle we will use is to separate the processes needed to form the desired nano-scale architecture from the subsequent formation of the active semiconductor-semiconductor heterojunctions at which charge separation is achieved. Central to our approach is the use of ‘sacrificial’ polymer structures that provide excellent control of nano-scale morphology, and their later replacement with active semiconductors. We will use the controlled nano-scale structures produced using di-block copolymers | £1,320,959 | 2008 - 2011 | |
Engineered hierarchical nano-structures for optimised hybrid photovoltaic devices | EPSRC | The overall aim of this project is to generate hierarchical structures with defined architectures at both the meso and macro scale, in order to optimise the efficiency of organic-inorganic hybrid solar cells. In this Grand Challenge we intend to develop novel hybrid-cells consisting of cheap inorganic electron transport matrices and readily manufactured organic molecules that both absorb light and transport holes. The efficiency of the cells will be maximized by engineering the interface between the materials on the nano-scale. Our Grand Challenge is to develop inorganic-organic-hybrid-photovoltaic cells which through interface engineering at the nano-scale are significantly more cost effective than currently available devices. The programme will be a joint venture between the London Centre for Nano-technology at Imperial College London and Warwick University. Collaborations are in place with Colleagues from the McDiarmid Institute for Advanced Materials and Nano-technology in NZ and with Kodak, UK. | £631,171 | 2008 - 2011 | |
Optimising polymer photovoltaic devices through control of phase-separation | EPSRC | In this project, which is being carried out at the Universities of Cambridge, Sheffield and Cardiff, a comprehensive mechanistic understanding is developed of the self-assembly processes by which nano-scale structure arises within such PV applicable materials. In particular we propose to study the evolution of nano-scale phase-separation during film casting using X-ray scattering. We will also utilize a range of complementary microscopy techniques ranging from environmental scanning electron microscopy, to time-resolved near field microscopy. The combination of such techniques will permit us to develop a complete picture of film structure from molecular to microscopic length-scales. | £1.1m | 2008 2011 | |
Optimising polymer photovoltaic devices through control of phase-separation | EPSRC | In principle, photovoltaic devices could meet all our energy requirements in a sustainable way, but at the moment the capital expense of conventional photovoltaics is too great to be competitive, and the volume in which they can be produced is much too small to make a serious dent in our electricity generating needs. Their relatively high manufacturing cost and the difficulty of scaling the manufacturing process is an intrinsic feature of their energy-intensive fabrication process. In contrast, non-conventional PVs based on organic semiconductors can be processed from solution using high-volume roll-to-roll printing technologies, offering the possibility of large area devices being fabricated on flexible substrates at very low cost. Unfortunately at present, organic PV devices are characterized by prohibitively low external power efficiencies (< 6 ). Closing the gap in efficiency between organic and inorganic PV devices is a significant challenge / one which will require a full microscopic understanding of the processes that currently limit organic PV efficiency. The most promising organic PV devices are currently based on solution-cast blends of conjugated polymers doped with fullerene derivatives. This research was carried out by Diamond Light Source Ltd and the University of Sheffield. | £69,564 | 2008 - 2011 | |
Self-organized nano-structures and transparent conducting electrodes for low cost scalable organic photovoltaic devices | EPSRC | The development of cheap renewable energy sources is required to reduce the environmental effects associated with the use of conventional fossil fuel based energy sources. Of all the renewable energy technologies, solar energy has the greatest potential as a world power source. For this reason, solar photovoltaic (PV), the direct conversion of sunlight to electricity, is expected to play a significant role in future electricity supply. This multidisciplinary project brings together chemists, physicists, materials scientists and engineers with world-leading expertise in metal oxide electrode design, polymer synthesis and manufacturing. This project being researched at the Imperial College, London also involves collaboration with Pilkington Glass, Merck Chemicals and University of Bath. | £1.8m | 2008 2011 | |
High-efficiency Block Copolymer Solar Cells: A Scalable Prototype for Low Cost Energy Generation | EPSRC | Widespread implementation of photovoltaic electricity to meet changing energy demands requires a step-change in the cost of photovoltaic power.

Low-cost Extremely Thin layer Absorber (ETA) Solar Cell: A Novel approach to make the conformal ETA Layers | EPSRC | The Extremely Thin Absorber-layer (ETA) solar cell is a relatively new PV configuration. In materials viewpoint, there are a large number of semiconductor materials available that are suitable to employ in ETA cell configuration. Most of them are yet to be tested in ETA cell. The first part of the project will be aimed at screening semiconductor material combinations to find out novel material combinations (high band gap n-type semiconductor/low band gap light absorbing semiconductor/high band gap p-type semiconductor) for ETA cells. This will be done by aligning the band gap and band edges of semiconductors. The next part of the project is the construction of the integrated ALD and CVD deposition system. The main advantage of constructing this deposition system is that it will give us the capability of depositing conformal layers of light absorbing low band gap semiconductor materials on high aspect ratio of microstructures. The system will also be capable of deposition of pin-hole free compact layers and deposition of p-type high band gap semiconductors on high aspect ratio microstructures. This research is being carried out by Loughborough University. | £292,938 | 2008 - 2011 | |
Nano-crystalline Photodiodes: Novel Devices for Water Splitting | EPSRC | The fossil fuel reserves of the world are rapidly diminishing and are also the prime cause for global warming. Solar energy represents a major, largely untapped energy source which could easily satisfy current and future global energy demands. Any solar energy conversion device must be inexpensive per m2, efficient and long-lasting. In this programme, novel, inorganic water-splitting systems, called macro-photocatalytic diode cells, MPCDs, utilising a range of new and established visible-light absorbing photocatalyst materials, will be developed for splitting water using sunlight in separate compartments. The latter feature is important as it will minimise, if not eliminate, the various efficiency-lowering recombination reactions associated with mixed product generation. The work programme involves a number of novel aspects including: the preparation of new nano-particulate, crystalline photocatalyst materials, fabricating them into different novel photodiode formats and the synthesis and utilisation of new redox catalysts. The use of nano-particulate semiconductor photocatalysts, made via continuous hydrothermal flow synthesis, CHFS, in conjunction with gel casting for robust porous supports, is a particularly important and novel advance, as too is the proposed combinatorial approach to the preparation of photocatalyst films by CVD. The project at the University of Strathclyde will develop a significant amount of the underpinning science required for the fabrication of the final, optimised, efficient MPCDs and include a study of the underlying reaction mechanisms, using time-resolved transient absorption spectroscopy. The proposal offers a route to achieving a step change in efficiency for energy capture from the sun and aims to deliver efficient, scalable demonstrators of the MPCD technology, suitable for development into pilot plant systems in the second phase of funding. | £518,659 | 2008 -2011 | |
High-efficiency Hybrid Solar Cells for Micro-generation | EPSRC | This proposal assembles a consortium of chemists, physicists, materials scientists and electrical engineers from The University of Manchester and Imperial College London to address this need through the development of new low-cost, high-efficiency, demonstration solar cells for micro-generation. We propose new designs for hybrid organic/inorganic devices which integrate flexibility and stability with inexpensive materials and solution based processing. | £1,012,365 | 2007 2011 | |
Novel Inline Deposition System for High Performance CIGS Solar Cells | EPSRC & TSB | CIGS (copper indium gallium selenide) solar cell structures have been identified as technologically important for the next generation of solar power production. They offer the advantages of being substantially less expensive to produce than crystalline devices and offer higher efficiencies than other non-crystalline photovoltaic materials. Currently, CIGS solar cells are typically produced using three separate deposition systems - two for the electrical contacts and one for the CIGS layer. The project aims to eliminate the requirement for three separate systems by combining all the processes into one system. This offers two important advantages that will ultimately result in the improved competitiveness of the process; the initial capital equipment cost will be lower than for three individual vacuum deposition systems and the inline nature of the system will allow higher throughput than conventional batch systems. The system will also demonstrate the proof of concept for roll-to-roll coating and continuous throughput systems. This research is being carried out by Loughborough University. | £84,508 | 2007 - 2011 | |
Magnetic field- and pressure- optical effects in CuInSe2, CuGaSe2 and CuInS2 | EPSRC | The development of improved sources of renewable energy is of extreme importance in order to reduce dependence on fossil fuels. Solar energy leads the way as the most environmentally friendly and abundant of such resources since the Sun transmits to the earth surface an amount of energy 100,000 times greater than present world energy consumption. A range of materials are employed for solar cells and here we propose work on chalcopyrite semiconductors which offer particular advantages, namely (1) extremely high absorption coefficients, higher than any other known semiconductor (2) energy gaps close to the optimal values for terrestrial and space conditions (3) robustness and relative insensitivity to irradiation by both high energy protons and electrons as a result of efficient self-healing mechanisms at room temperature. The materials to be studied are CuInSe2, CuGaSe2 and CuInS2 semiconductors as are currently used in the absorber layer of solar cells which hold record conversion efficiencies for thin-film photovoltaic devices (19 for Cu(InGa)Se2- photovoltaic devices and 12 for CuInS2-based ones) and demonstrate superior stability when compared to any other thin-film solar cell. The band-gap of CuInS2 (Eg 1.53 eV) almost ideally matches the solar spectrum whereas in CuInSe2-based cells the optimum efficiency is achieved by alloying CuInSe2 (Eg 1.05 eV) and CuGaSe2 (Eg 1.68 eV). Progress so far with Cu(InGa)(SSe)2-based technologies has mostly been attained using scientific intuition rather than knowledge-based design. Here we propose to use optical spectroscopy, in the presence of magnetic fields and high pressure, to improve the understanding of these materials and apply this to the development of improved solar cells. This research is being carried out by the University of Strathclyde. | £475,911 | 2007 - 2011 | |
Development of a Novel Tunnel-junction-free Concentrator Cell and its Evaluation for a Smart Windows Application | EPSRC | We propose to develop a novel type of solar cell that will generate electricity from sunlight with efficiency above 30 . This is at least twice the efficiency of the cells currently used to power roadside signs and comparable with the highest efficiency tandem cells which power satellites in space. However, our cell offers many advantages over the tandem, in particular the absence of a tunnel-junction. This means they can cope with the large variations in the intensity and spectral content of sunlight on buildings and in the light-concentrating systems which reduce the cost of solar electricity. This research is being carried out by Loughborough University. | £71,289 | 2009 - 2010 | |
Metal substrate mounted flexible dye sensitised semiconductor solar cells | EPSRC | Low cost photovoltaic (PV) coatings in the modern built environment promise great financial /environmental benefits, potentially competing with mainstream energy sources.

This research was carried out by Swansea, Bath and Bangor University and Imperial College. | £1.4m | 2007 2010 | |

This research is being carried out by the University of Warwick. | £441,841 | 2007 - 2010 | |
Self-assembling conjugated macromolecules for organic field effect transistors and solar cells | EPSRC | The design and construction of an ideal material for organic semiconductor devices requires the careful consideration of a range of physical properties. In some cases, what would represent good materials characteristics for one type of device may be highly detrimental to the efficiency of another. Intermolecular pi-pi interactions symbolise one good example: in organic light emitting devices, photoluminescence is quenched by these attractions and the device efficiency is reduced dramatically; in organic field effect transistors (OFETs), it is desirable to promote pi-pi interactions throughout the bulk, so that charge mobility can be maximised. In this proposal, we aim to prepare materials for organic photovoltaic (OPV) devices and OFETs. The novelty in this work originates from very recent results, in which we demonstrate that highly soluble materials with conformational freedom in solution are able to self-assemble in the solid state to give highly planar and conjugated structures. Such levels of planarity, which maximise the possibility of pi-pi interactions, have only been achieved previously with ladder or ribbon type structures which possess inherent solubility problems. In our systems, long range planarity can be achieved through the use of weak, non-covalent interactions; to date, this approach has not been given significant consideration and is therefore waiting to be exploited. This research is being carried out by Imperial College London. | £116,852 | 2007 - 2010 | |
PLATFORM: Molecular Engineering Rules in Functional Nano-scale Assemblies | EPSRC | The organisation of molecular and biomolecular components on the 1-100 nano-meter scale to achieve a desired functionality is central to the current growth of interest in nano-materials and nano-technology. Such structural organisation is of course already fundamental to the function of many biological macromolecules; the emulation of such structural and functional control is now a central element of many chemical approaches to functional materials and devices. The applicants of this proposal all head internationally leading research programmes addressing the engineering principles of functional nano-scale assemblies. The rationale behind all of these studies is the determination of the underlying structure / function relationships which will allow the rational design of specific nano-scale assemblies to achieved a desired functionality. The nano-scale assemblies studied by the applicants all lie close to the chemistry/life sciences interface and include natural and synthetic redox proteins, the integration of such redox proteins with nano-structured inorganic materials, and biomimetric approaches to solar energy conversion and light driven water splitting. This research is being carried out by Imperial College London. | £411,774 | 2005 - 2010 | |
A novel device architecture for high-performance organic solar cells | EPSRC | The project is a feasibility study carried out by the University of Cambridge which will establish whether by aligning the polymer chains along the direction of the electric field that is present in the device it is possible to reduce recombination losses significantly.

Modelling Thin Film and Dye-sensitised Solar Cells | EPSRC | Thin film and dye sensitised solar cells encompass different approaches to solar cell design. What they have in common is the existence of contoured interfaces either at grain boundaries (thin film cells) or between the layers transporting the charges (dye-sensitised cells). The finite element technique allows us to develop electrical and optical models that consider these interfaces. By predicting photocurrents and photovoltages and quantities that characterise the cells such as transient currents, our models will aid in understanding cell operation and identifying the key factors limiting solar cell performance. There will be close interaction with UK experimental colleagues who can give us information on fundamental mechanisms which can be imported into the models. Our models can then be used to help interpret experimental data, providing feedback on the device physics of the solar cells. This will be done through collaboration with the EPSRC’s Supergen programmes and via the EPSRC funded network PVNET. Our work will thus provide a nucleus for photovoltaic device modelling in the UK. This research was carried out by Cranfield University. | £213,493 | 2005 - 2008 | |
