Energy Secretary Steven Chu announced June 16 the offer of a conditional commitment for a $275 million loan guarantee to Calisolar Inc. to commercialize its innovative solar silicon manufacturing process. The process is expected to produce silicon for use in solar cells at less than half the cost of traditional polysilicon purification processes. The manufacturing plant will produce 16,000 MT of solar silicon per year and will create 1,100 permanent jobs and 1,000 construction jobs.
