Green speaks At the recent "EU PVSEC" conference organized by the International Society for Solar Cells, Professor Martin Green from the University of New South Wales (UNSW) in Australia presented groundbreaking research on improving the efficiency of crystalline silicon solar cells. Green is a well-known figure in the field, having previously set a world record with a 25% conversion efficiency for silicon-based cells. In his presentation titled "Silicon Wafer-Based Tandem Cells: The Ultimate Photovoltaic Solution," Green introduced a promising approach to push beyond the current efficiency limits of silicon. By combining silicon with other materials, he demonstrated that the overall efficiency could exceed 40%, with potential reaching as high as 47.5% when multiple layers are stacked. This method, known as a tandem structure, allows different materials to capture various parts of the solar spectrum more effectively. When only silicon is used, the maximum theoretical efficiency is around 29%. However, by overlaying other advanced materials on top of the silicon layer, the performance can be significantly improved. Green highlighted several candidate materials, including III-V compounds like GaAs, which are commonly used in space applications and concentrated photovoltaics. He also mentioned CZTS, a thin-film material that doesn't require indium, and perovskite materials, which have shown great promise in dye-sensitized solar cells. While specific details about the research were not disclosed, Green emphasized that each material has its own strengths and trade-offs in terms of efficiency, cost, and scalability. A technician from a leading solar cell manufacturer at the event commented that "this direction, going beyond the silicon limit, is something we're actively exploring." As renewable energy continues to gain momentum, innovations like these could play a crucial role in making solar power more efficient and cost-effective. With ongoing research and development, the future of photovoltaics looks brighter than ever.
