Summary
Passivating Cadmium free Cu2ZnSn(S,Se)4 solar cell by contact engineering. The project aims to develop new solar cells made of low cost abundant elements. The cells are cadmium-free copper zinc tin sulphide (CZTS) cells formed by rear contact passivation and damage-free evaporated front layers. CZTS has the same efficiency potential as current commercial copper indium gallium selenide (CIGS) cells, but consists of low cost, abundant elements. Concepts and methods will be developed for passivatio ....Passivating Cadmium free Cu2ZnSn(S,Se)4 solar cell by contact engineering. The project aims to develop new solar cells made of low cost abundant elements. The cells are cadmium-free copper zinc tin sulphide (CZTS) cells formed by rear contact passivation and damage-free evaporated front layers. CZTS has the same efficiency potential as current commercial copper indium gallium selenide (CIGS) cells, but consists of low cost, abundant elements. Concepts and methods will be developed for passivation of CZTS solar cells via both back and front contact engineering. The cadmium- free buffer layer will be investigated and the application of CZTS will be expanded. This work may be applied to CIGS improvement and could give CZTS materials a significant role in the rapidly growing photovoltaic industry.Read moreRead less
Advanced metallisation for III-V Photovoltaic Solar Power Systems. This project aims to augment the overall electrical efficiency of concentrator photovoltaic solar systems that provide large-scale generation of cheap, clean electricity. Existing concentrator solar cells are highly efficient (>40%) but their performance is hampered by thick front-metal contacts that shade the cell.

This project aims to augment the overall electrical efficiency of concentrator photovoltaic solar systems that provide large-scale generation of cheap, clean electricity. Existing concentrator solar cells are highly efficient (>40%) but their performance is hampered by thick front-metal contacts that shade the cell. The project is expected to develop a new concentrator solar cell metalisation and insulation technology. The benefit of the project will be a direct increase in the system efficiency and simplified manufacturing of the concentrator solar receiver, which in turn reduces the cost of the concentrator power plant constructed by our Australian project partner RayGen Resources Pty Ltd.Read moreRead less
