Preparation of silicon materials by physical method and Siemens method
1. Physical methods to produce solar-grade (SOG) silicon In the manufacturing cost of crystalline silicon solar cells, polysilicon raw materials account for a large proportion. In order to reduce the manufacturing cost of polysilicon materials, the polysilicon materials can be purified by physical methods (sometimes called metallurgical methods) or a combination of physical methods and chemical…
