One of the major lines of solar energy development is the creation of environmentally friendly, wasteless and cheap solar-grade silicon production technology. Currently the main silicon production technologies are based on reduction of silicon hydrogen chloride compounds: trichlorosilane, tetrachlorosilane, monosilane. These technologies use harmful and potentially dangerous compounds in quantity...
