What is polysilicon used for?
Here is a primer. Polysilicon, a high-purity form of silicon, is a key raw material in the solar photovoltaic (PV) supply chain. To produce solar modules, polysilicon is melted at high temperatures to form ingots, which are then sliced into wafers and processed into solar cells and solar modules.

What is the grain size of polysilicon?
Polysilicon is a material with a grain size that ranges between 1 mm and 1 μm . If the range is extended to 0.1 μm, these are called multicrystalline silicon or sometimes polycrystalline silicon. So, this form of material has a very small grain size that does not reach 1 μm that is used as the standard material in solar cells.
Why are PC-silicon cells used in solar cells?
The films of pc-silicon cells are exploited to get some advantages over the bulk silicon (Si) solar cells. This is a most abundant material, which is why it is widely used for film technologies such as cells. Toxicity is a major problem for some of the technologies such as cadmium telluride (CdTe) base cells but not for silicon cells.
What technology is used to make polysilicon?
Three are three main technologies to produce polysilicon. The ‘modified Siemens process’ is currently the dominant technology in China. Trichlorosilane (TCS) is produced using two readily available metallurgical-grade silicon (of 95-99% purity) and liquid chlorine.
How will Xinjiang impact the polysilicon market?
A potential market impact could be a further tightening of the polysilicon market, especially if a premium emerges for polysilicon sourced outside of Xinjiang, which is a low-cost producing region due to its low electricity costs. This could cause polysilicon prices to rise and hold at higher levels.
Which material is used in Si thin-film solar technology?
Due to these excellent properties, it is used in Si thin-film solar technologies. The ceramic material designed by the solid solution of SiO 2 and Al 2 O 3 is called Mullite. It has optical properties similar to alumina and a TEC matched with silicon .
