The production and purification of polysilicon is the first step in the manufacturing process to produce conventional silicon solar cells. The fabrication of polysilicon begins with a carbothermic reduction of SiO 2. Quartzite, the source of SiO 2, is mixed with carbon—sourced from materials such as coal, coke (fuel), graphite or wood—in a ...

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.
