The production and purification of polysilicon is the first step in the manufacturing process to produce conventional silicon solar cells. The fabrication of polysilicon begins with a carbothermic reduction of SiO 2. Quartzite, the source of SiO 2, is mixed with carbon—sourced from materials such as coal, coke (fuel), graphite or wood—in a ...
