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.
Nickel powder optimization cuts TOPCon solar cell metallization costs by 6.8% without compromising efficiency
UNSW researchers demonstrated a 6.8% reduction in rear-finger raw-metal costs for TOPCon cells by optimizing nickel powder characteristics for partial silver replacement. This work highlights how specific powder properties influence electrical performance and printability, offering a pathway to lower metallization expe
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.
Analysis of Q3 Solar Power Earnings in China: Eight Major Companies Report Combined Loss of 27.7 Billion Yuan, Aiko Solar Achieves Solo Profitability
China's eight major solar companies reported a combined net loss of 27.7 billion yuan for the first three quarters of 2026, driven by a 53.9% drop in domestic installations. This financial divergence highlights the impact of low module prices and the upcoming 2027 national standards on industry consolidation.
