The research report alleges that Uyghurs, a Muslim minority group based in Xinjiang, China, have been forced to produce polysilicon, a key material used to make solar panels, under state-sponsored labor transfer programs over the last two years.Kevin He, a spokesperson of Daqo New Energy Corporation, told Insider that the Xinjiang-based manufacturer doesn't employ any Uyghur workers and said China has no need to supply workers through the labor-transfer program.China's dominance of the global solar market may expose the solar supply chain to a greater risk of disruptions from geopolitical disputes, extreme weather, and shifts in the economy, Seaver Wang, a researcher involved in the study, told Insider.The US passed a law in June of 2021 banning some of the imports of solar materials from the Xinjiang region, a move that could make it more expensive for the Americans to switch to solar energy."We think it is key for the clean tech industry to send a strong signal now that it will not tolerate sourcing from Xinjiang-based manufacturers complicit in the region's oppressive policies," Wang said."
