Heterojunction technology improves solar cell efficiency, making it a critical focus for manufacturers seeking to reduce the levelized cost of energy in the industry.
34% Efficiency Solar: China Bans Export of Its Future Cells
China has proposed export restrictions on 12 photovoltaic technologies, including TOPCon and heterojunction architectures, citing national security concerns. This move impacts the global supply chain for high-efficiency solar cells, which are essential for advancing the performance and cost-effectiveness of future solar installations.
China: Central and State-Owned Enterprises' Solar PV Centralized Procurement Has Truly Changed
Central and state-owned enterprises in China are shifting centralized procurement criteria from price-per-watt to module conversion efficiency, with new standards mandating specific efficiency tiers for TOPCon, HJT, and BC technologies starting in 2027. This regulatory change forces manufacturers to prioritize high-efficiency production capabilities over cost reduction to secure large-scale utility contracts.
Solar, China Raises Industrial Standards
China's MIIT proposed 2026 photovoltaic manufacturing standards with differentiated efficiency thresholds for TOPCon, HJT, and BC cells. These updates aim to improve quality and address overcapacity in the solar supply chain.
China's solar technology plan signals new phase in global renewable energy industry
China's Ministry of Commerce proposed a framework to prohibit exports of advanced solar manufacturing technologies, including perovskite and tandem cells, while restricting others. This move impacts global supply chains by controlling the transfer of key production methods to other nations.
