CATL confirms significant upgrade to sodium-ion battery product range and scale into 2026
CATL announced it expects a new trend of “sodium and lithium batteries shining brightly together.”
Trina Solar posts new milestones for tandem efficiency, module power
Trina Solar says new certified results in perovskite-crystalline silicon tandem cells and modules demonstrate progress toward industrial-scale next-generation PV.
Trina Solar completes sale of 5 GW U.S. module plant to T1 Energy
Trina Solar has completed the sale of its 5 GW US solar module factory to T1 Energy, exiting direct manufacturing while retaining a minority equity stake.
PV redox flow battery with 4.2% solar-to-electricity conversion efficiency
Scientists in China have constructed and tested a device that uses redox couples paired with a single triple-junction amorphous-silicon photoelectrode. When tested under a xenon lamp simulating one sun, the device achieved an average solar-to-electricity conversion efficiency of 4.2%.
Aiko achieves 34.76% efficiency for 2-terminal perovskite-silicon tandem solar cell
The Chinese manufacturer said its 2-terminal 34.76%-efficient perovskite-silicon tandem lab-scale cell is based on heterojunction technology and developed by a collaboration of Solarlab Aiko Europe, Aiko headquarters, and its R&D in Yuwi, China.
Research shows vacuum melting is key to efficient silicon kerf recycling
Researchers in Norway investigated the melting behavior of silicon kerf agglomerates under different atmospheres and temperatures to improve recycling for solar-grade silicon. They found that vacuum melting enhances deoxidation and produces a homogeneous, oxide-free melt, while agglomerate size has little effect on melting behavior.
The Hydrogen Stream: CMB.Tech secures China green ammonia offtake
CMB.Tech has secured an offtake agreement for renewable ammonia from CEEC Hydrogen Energy’s 800 MW wind-and-solar-powered project in China, while Germany’s Gascade Gastransport said it has converted about 400 km of gas pipelines to form a new hydrogen transport corridor.
China files WTO complaint against Indian solar subsidies
China’s commerce ministry has raised a complaint at the World Trade Organization (WTO) regarding India’s solar subsidies, claiming they give the country’s domestic industry an unfair advantage and harm Chinese interests.
Using horizontally connected salt caverns for compressed air storage
Researchers in China have investigated the long-term stability of horizontally connected salt caverns used for compressed air energy storage. They found about 85% of the existing salt caverns in their home country are are suitable for this configuration.
Aiko achieves 24.8% efficiency in commercial solar module production
The result concerns the company’s Comet 3N modules and has been confirmed by TÜV Nord in Germany.
