The former is the key raw materials in cell manufacturing, and the latter directly determines the conversion efficiency of the PV modules. Polysilicon is a highly pure form of silicon that is produced by a chemical purification process.
The manufacturing process of polysilicon involves several complex steps, starting with the extraction and purification of raw materials and ending with the production of high-purity polysilicon chunks or granules. The journey of polysilicon begins with its primary raw material: quartz sand.
However, Elkem of Norway developed a process for polycrystalline solar-grade silicon production and is building a 5000 metric tons plant . The major problem of the chemical route is that it involves the production of chlorosilanes and reactions with hydrochloric acid.
Solar-grade polysilicon, typically with a purity of 6N to 9N, is used to produce multi-crystalline and mono-crystalline silicon wafers for solar cells. While solar-grade polysilicon has a lower purity compared to electronic-grade, it is more cost-effective and still provides sufficient performance for solar energy conversion.
Polysilicon is a highly pure form of silicon that is produced by a chemical purification process. After constant refinement and innovation of the production process, three core polysilicon technologies have been derived: the improved Siemens process, the thermal decomposition of silane and the fluidized bed.
The polycrystalline silicon manufacturing process is a complex and energy-intensive journey that transforms abundant raw materials like quartz sand into a high-purity, versatile material essential for the solar photovoltaic and electronics industries.
