The future of PV industry and SG‐Si materials

The future demand of solar grade silicon (SG-Si) materials is discussed from PV Industry future trend in this paper. The production of ultra-purity silicon (UP-Si) materials (including EG-Si and SG-Si) will be a big industry and will have a great contribution to world society with high-speed development of PV industry. For demand of future, the purity issue of SG-Si is discussed from requirement of solar cell performance and operation. (© 2009 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim)
