Labor and resettlement programs targeting Uighur populations in China’s Xinjiang region have been linked with companies producing a significant portion of the world’s polysilicon, according to a forthcoming report that draws a connection between the solar industry and forced labor in the region. The report, written by consultancy Horizon Advisory, points to “indicators of forced labor” from companies such as Jinko Solar and some of the largest polysilicon suppliers in the world, accounting for well over a third of worldwide capacity. Forced labor associated with an essential raw material used in manufacturing most solar panels, the authors write, implicates a significant swath of the entire industry.
