Development of high-performance Si/Ge superlattice thermoelectric materials with optimization of lattice periodic thickness. Thermoelectric generation systems convert waste heat into electrical energy irrespective of source size and without the use of moving parts or the production of environmentally deleterious wastes. This would conserve fuel and energy, and reduce environmental emissions. Success of this program will facilitate the development of thermoelectric materials, which has enormous i ....Development of high-performance Si/Ge superlattice thermoelectric materials with optimization of lattice periodic thickness. Thermoelectric generation systems convert waste heat into electrical energy irrespective of source size and without the use of moving parts or the production of environmentally deleterious wastes. This would conserve fuel and energy, and reduce environmental emissions. Success of this program will facilitate the development of thermoelectric materials, which has enormous international market, in Australia. It will open up an avenue for searching out potential thermoelectric materials for practical applications. This program will also provide an education platform to intensively train high quality postgraduates at the international level.Read moreRead less
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
