The supply chain snarl that tripled the price of a key raw material for solar panels is about to get fixed, clearing the way for a renewed boom in the use of the clean energy technology. China is spending billions on new factories to produce polysilicon, used to make photovoltaic cells for solar panels. Global capacity has already been boosted by more than a quarter in the past two months, and it will double by early next year. That should help rein in prices of the material after surging costs slowed the pace of new renewables projects. As component shortages to a squeeze on shipping drive up prices for everything from natural gas to beef, polysilicon is an example of how some supply woes will likely prove transitory. It also shows how China is using its industrial heft to ensure its continued dominance in solar, a sector that’s key […]
