Key facts
- China proposed export controls on 12 solar-manufacturing technologies.
- The technologies include those for thin wafers, perovskite and tandem solar cells.
- Large-scale fluidized-bed polysilicon production technologies are also targeted.
- Advanced solar cell manufacturing technologies like TOPCon, HJT and XBC will be restricted, but not prohibited.
China's Ministry of Commerce has proposed adding 12 technologies used in solar equipment manufacturing to its export-control list, citing national security concerns. The ministry stated that these technologies are increasingly being used in sensitive areas such as aerospace and national defense, necessitating greater oversight.
This move could impact global solar supply chains and plans by companies like Tesla to expand production. China has previously curbed exports of solar-manufacturing technology to India, aiming to maintain its dominance while India seeks to build domestic manufacturing capabilities.
