Due to forced labor concerns, parts of the international solar supply chain have shifted from China to other countries. For example, polysilicon manufacturers like Wacker in Germany, Hemlock Semiconductor from the US and OCI Malaysia have all increased their deliveries of this solar cell and semiconductor raw material to Vietnam, according to polysilicon market specialist Bernreuter Research on Wednesday. Wacker, Hemlock and OCI Malaysia increased their polysilicon exports to Vietnam by a combined 78 percent to 33,265 tons in 2023.
