Polysilicon Drop May Stop Output From 90% of China’s Factories

China’s polysilicon factories, which supply the raw ingredient for solar panels, may suspend output this month because of a slump in prices, an analyst at an industry trade group said.

Xie Chen, who conducted a study of the polysilicon industry for the China Nonferrous Metals Industrial Association, said about 90 percent of the plants accounting for half of the output from China risk closing, forcing solar module makers to import more of the raw material from abroad.
