China Proposes New Export Controls on Key Solar Manufacturing Technologies

China's Ministry of Commerce and Ministry of Industry and Information Technology have proposed new export controls targeting the manufacturing technology behind advanced perovskite and tandem solar cells. A temporary requirement for companies to register planned exports of these technologies took effect on October 16, 2026, signaling a broader policy to extend technology-transfer controls to critical sectors like clean energy. This move could significantly impact global solar supply chains and the development of high-efficiency solar technology outside of China.
