Advances in the Dow Corning process for solar-grade siliconThe Dow Corning process consists of the carbothermic reduction of silica to produce silicon that is then purified by unidirectional solidification. The process has produced silicon of semiconductor quality with respect to all elements except boron and phosphorus at about 10 ppma and aluminum at 0.1 ppma. Solar cells produced from this silicon gave AM0 conversion efficiencies of 11%. A process cost analysis is presented.
