The reality is polysilicon is a very timely - new polysilicon production is a very timely process, time intensive process. And even though construction on new facilities has begun, it's not really expected to come online in any sort of meaningful capacity until very late into 2021. But more likely into 2022 after next year's Chinese New Year.
Polysilicon. Polysilicon, poly-Si, or polycrystalline silicon, is a material consisting of a number of smaller crystals or crystallites. Deposition of polysilicon is one of the most important CVD processes used in microfabrication. Polysilicon is composed from trichlorosilane (SiHCl 3) or silane (SiH 4) through the following reactions:
