China considers export restrictions on advanced solar technologies
Beijing has proposed strict export bans and licensing requirements for high-efficiency solar manufacturing technologies, including perovskite and tandem cells.
Key points
- China proposes adding 12 photovoltaic technologies to its export prohibition and restriction lists.
- The draft measures cover high-efficiency perovskite, tandem cell, and advanced silicon production processes.
- Interim registration requirements for planned technology exports took effect immediately on October 16.
What happened
According to pv magazine, the Chinese Ministry of Commerce and the Ministry of Industry and Information Technology have put forward a joint proposal to restrict overseas transfers of advanced photovoltaic manufacturing equipment and techniques. Published under Joint Announcement No. 48 of 2026, the draft introduces controls on 12 specific solar technologies as part of a wider public consultation lasting until November 15.
The proposed rules target production parameters such as conversion efficiencies and wafer dimensions rather than finished solar panels. The restrictions cover high-performance perovskite-silicon tandem configurations, single-junction modules, advanced polysilicon production lines, and thin silicon wafer manufacturing know-how.
What comes next
While the full export bans remain subject to the consultation process, interim registration mandates took effect immediately upon the announcement on October 16. Exporters must now register planned technology transfers, intellectual property sharing, and foreign ownership adjustments through an online portal managed by the commerce ministry.
Analysts note that if finalised, the regulations could increase compliance costs and delay overseas photovoltaic manufacturing initiatives. The controls may also strengthen Beijing's influence over the global deployment of next-generation solar energy infrastructure.

Context from CEII
Renewables are the fastest-growing part of the world’s energy system. The COP28 goal is to triple capacity by 2030, and solar mini-grids are the fastest route to power for millions of people without electricity.
