EU ban on Chinese inverters sparks strong response from Beijing
China strongly criticized the EU’s ban on Chinese inverters in EU-funded solar projects, warning it could damage trade relations, supply chains, and Europe’s energy transition.
Anker Solix launches 7 kWh modular battery with 5 kW bidirectional inverter
The system features AI-driven energy management, 10,000-cycle battery life, and scalable expansion up to 126 kWh.
Longi announces world record efficiency of 28.13% for silicon solar cell
Longi claims to have achieved the world’s highest efficiency for a silicon solar cell. The result was confirmed by Germany’s Institute for Solar Energy Research Hamelin (ISFH).
Japanese scientists build all-perovskite tandem solar cell with 30.2% efficiency
The four-terminal tandem device relies on FAPbI₃ nanoparticles and a spectral splitting design, combining a 24.4% wide-bandgap top cell and a 21.5% narrow-bandgap bottom cell to reach 30.2% efficiency. The system improves light utilization by directing different wavelengths to optimized subcells.
Rethinking silver paste design for TOPCon, LECO solar cells
Researchers in China have developed an evaluation framework to better assess fine-line silver pastes for TOPCon and LECO solar cells. The approach links laboratory characterization directly with production-line performance, addressing the limitations of conventional evaluation methods.
Trina Solar TOPCon patents invalidated in US ruling involving Canadian Solar
The U.S. Patent and Trademark Office has invalidated all claims of two TOPCon solar cell patents previously asserted by Trina Solar against Canadian Solar subsidiaries.
JinkoSolar debuts rooftop PV module weighing 7 kg/m2
The Chinese manufacturer said its lightweight Light Diamond TOPCon module delivers 560 W at 24.94% efficiency.
Perovskite–silicon tandem solar cells using zinc-doped tin oxide achieve comparable performance to indium tin oxide counterparts
Fraunhofer ISE-led researchers demonstrated zinc-doped tin oxide (ZTO) as an indium-free alternative to indium tin oxide (ITO) for recombination layers in fully textured perovskite–silicon tandem solar cells. ZTO delivers comparable device efficiencies of 27–28% under current-matching conditions, offering a scalable, indium-free pathway for high-performance tandem photovoltaics without efficiency loss.
Silver demand from PV industry expected to drop 19% this year
A new report from Metal Focus reveals that global silver market remains structurally tight, with elevated prices, a fifth consecutive annual supply deficit in 2025, and ongoing mine and recycling constraints despite modest production growth. At the same time, PV-driven silver demand is falling sharply due to cost pressure and thrifting.
Solarport launches modular PV carport series
Solarport has launched the modular PowerPark PRO PV carport series, designed to meet UK/EU parking standards and adapt to various site layouts with multiple configurations and orientations.
