New Directions in Silicon Solar Cell Technology. The fabrication of pure silicon is energy intensive, but solar cells can return 10 times more energy than is used to fabricate them. By investing in the development of silicon solar cells, Australia will develop a technology capable of encapsulating its vast coal resources within pure silicon. This has the potential to create an export market of clean energy and have an explosive effect on the growth of the local industry and skilled jobs.

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

Summary
Combined reactor for the plasma-enhanced chemical vapour deposition (PECVD) of amorphous layers of silicon, silicon nitride and silicon oxide, and for Reactive Ion Etching. Our small, but very productive group (up to 30 publications per Discovery grant) has reached critical mass (8 people), and the acquisition of essential infrastructure is peremptory. Without the proposed plasma reactor our strong international impact (10 papers, one invited, at the 2003 world conference on photovoltaics) will ....Combined reactor for the plasma-enhanced chemical vapour deposition (PECVD) of amorphous layers of silicon, silicon nitride and silicon oxide, and for Reactive Ion Etching. Our small, but very productive group (up to 30 publications per Discovery grant) has reached critical mass (8 people), and the acquisition of essential infrastructure is peremptory. Without the proposed plasma reactor our strong international impact (10 papers, one invited, at the 2003 world conference on photovoltaics) will wane. This machine permits to deposit thin layers of silicon nitride and amorphous silicon and is a versatile tool for investigating silicon materials for photovoltaics and microelectronics. Such reactors have become an essential tool for silicon solar cell work. Most laboratories across the world have at least one, including UNSW, but access to the latter is impractical.Read moreRead less
Transparent metal oxides, a window of opportunity for silicon solar cells. This project aims to develop novel silicon heterojunction solar cells based on transparent conductive metal oxides (TCOs). Thin layers of zinc, gallium and molybdenum oxides present negligible absorption losses, which leads to a high output current. The project will optimise them as surface passivating layers, to achieve a high output voltage. TCOs can also provide good lateral conductivity, to boost the fill factor.

The proposed project is an example of applied research that utilises a frontier technology (superconductors) in an application with both national and community benefits. Fault current limiters are designed to protect electricity grids. The integration of superconductors in fault current limiting applications allows for this protection to be achieved in an energy efficient manner, since negligible impedance is applied to the network during the un-faulted state. Effective and efficient protection of the electricity network is of national interest, with any failure affecting industry and individuals. The proposed research team is in a leading position to develop the potential of this technology for both national networks and a world market.Read moreRead less

Improving silicon grain boundaries by linking electronic material quality and device manufacturing conditions.

This project develops our recent findings for improving silicon grain boundaries in electronic devices such as cheap solar cells, active matrix displays, thin-film transistors, etc. The performance of such devices and their applications have been limited mainly because no simple link between manufacturing conditions and device quality has been found. However, we recently verified a physical model description of grain boundaries on a broad range of devices, and this allows us to find such a link and to address prevailing problems from a new perspective. This will improve both the understanding and the manufacturing of such devices.Read moreRead less
