Development of very thin silicon solar cells for space applications. These space cells will include many of the significant improvements in silicon cells of the last 20 years, which have allowed close to the maximum possible efficiencies and the order of magnitude decrease in cost of terrestrial solar cells. Space cells require good radiation resistance to give good end of life performance. This project will use photovoltaic architectures, proven to give high performance for terrestrial cells, to develop ultrathin silicon cells with extreme light trapping and improved radiation tolerance to give high beginning and end of life efficiencies. These cells will be less than 5% of the cost of multijunction cells currently used in space.Read moreRead less
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.

It will also coordinate efforts with all the main university research groups in the country. Read moreRead less
Hot carrier solar cells: new approaches and demonstration of devices. The hot carrier solar cell aims to capture a large fraction of energy from solar photons normally lost as heat. This will give much higher efficiencies, and allow fabrication of cheap high efficiency devices. This can be achieved by modifying the way electrons lose their energy as heat, by blocking the lattice vibrations which cause this loss.

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.

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

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

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

The purpose of this project is to make available to the Australian semiconductor research community a facility to undertake specialist deposition and etching tasks needed for fabrication of next generation solar cells, microelectronics, optronics, and micro-electromechanical systems. The facility will have the flexibility to allow independent control of major process parameters, allowing development of new fabrication technologies which will be generic to a wide range of semiconductor materials. In particular, the facility will be unique in its ability to perform processes at low temperatures, and under conditions that allow optimisation of the deposition and etching processes, without compromising the performance of delicate devices or exceeding the maximum process temperature limitations found in many mainstream semiconductor materials technologies.Read moreRead less
