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.

Why has the polysilicon industry consolidated?
The polysilicon industry has increasingly consolidated, with the top-five companies accounting for 73% of global production in 2020 compared to 60% in 2017, according to BNEF. This is mainly due to a number of companies shutting down capacities in recent years after a period of overcapacity.
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.
