The Biden administration’s solar power ambitions are colliding with complaints the global industry depends on Chinese raw materials that might be produced by forced labor.
A big hurdle is polysilicon, used to make photovoltaic cells for solar panels. The global industry gets 45% of its supply from Xinjiang, the northwestern region where the ruling Communist Party is accused of mass incarceration of minorities and other abuses. Other parts of China supply 35%. Only 20% comes from U.S. and other producers.
