Polycrystalline silicon, or multicrystalline silicon, also called polysilicon, poly-Si, or mc-Si, is a high purity, polycrystalline form of silicon, used as a raw material by the solar photovoltaic and electronics industry. Polysilicon is produced from metallurgical grade silicon by a chemical purification process, called the Siemens process. This process involves distillation of volatil
Polycrystalline silicon: applications, and properties
There are mainly two types of photovoltaic panels that can be monocrystalline or polycrystalline silicon. Previously, seeds were obtained by pulling from the atmosphere of electronic grade polysilicon. The seed''s purity
