Overcoming performance limitations in multicrystalline silicon solar cells. This project aims to address the major impediments to improved efficiency of multicrystalline silicon solar cells, the most prevalent in industry today. Three key areas have been identified: understanding the fundamental source of carrier recombination in this material, the application of plasma silicon nitride to reducing this recombination, and developing a suitable technique for texturing the front surface of the cell ....Overcoming performance limitations in multicrystalline silicon solar cells. This project aims to address the major impediments to improved efficiency of multicrystalline silicon solar cells, the most prevalent in industry today. Three key areas have been identified: understanding the fundamental source of carrier recombination in this material, the application of plasma silicon nitride to reducing this recombination, and developing a suitable technique for texturing the front surface of the cells. By using novel, advanced techniques to gain a deeper physical understanding of these issues, it will be possible to develop new, cost-effective processes that improve efficiency and are applicable in industry.Read moreRead less
Lifetime spectroscopy of impurities in silicon solar cells. This project aims to apply recently developed experimental techniques to the important problem of characterising impurities in silicon, with a strong focus on solar cell applications. These new spectroscopic techniques, which are based on carrier lifetime measurements, are more sensitive and less ambiguous than most existing methods. The results will have important implications for solar cell technologies in two independent ways - first ....Lifetime spectroscopy of impurities in silicon solar cells. This project aims to apply recently developed experimental techniques to the important problem of characterising impurities in silicon, with a strong focus on solar cell applications. These new spectroscopic techniques, which are based on carrier lifetime measurements, are more sensitive and less ambiguous than most existing methods. The results will have important implications for solar cell technologies in two independent ways - firstly, by allowing accurate diagnosis of the performance-limiting impurities in standard silicon solar cells - and secondly, by identifying particular impurities which could boost cell performance beyond the conventional limit through the impurity photovoltaic effect.Read moreRead less
Design Of Practical Passive Cooling Radiators Utilising Spectrally Selective Covers And Surfaces. Radiative cooling offers a means to cool buildings sustainably without complex and costly heat pumps or air conditioners. Units similar to solar panels can be designed with surfaces which radiate mostly into the 8 - 12 micron atmospheric window, which has a radiance much less than for other wavelengths. Commercial development has been limited by problems associated with the degradation, performance ....Design Of Practical Passive Cooling Radiators Utilising Spectrally Selective Covers And Surfaces. Radiative cooling offers a means to cool buildings sustainably without complex and costly heat pumps or air conditioners. Units similar to solar panels can be designed with surfaces which radiate mostly into the 8 - 12 micron atmospheric window, which has a radiance much less than for other wavelengths. Commercial development has been limited by problems associated with the degradation, performance or cost of radiator surfaces. This project seeks to improve both performance and durability with innovative use of alternative materials and sputtered coatings suitable for mass manufacture, and to test the outdoor performance of laboratory produced radiative plates.Read moreRead less
