A more than 15% increase in silver prices over the past week is adding cost pressure to the solar supply chain, as silver paste costs currently represent around 30% of total PV module costs.

Conceived for stationary energy storage, the proposed sodium-ion battery configuration relies on an P2-type cathode material and an hard carbon anode material that reportedly ensure full-cell performance. Electrochemical testing revealed initial capacities of 200 mAh/g for the cathode and 360 mAh/g for the anode with capacity retentions of 42% and 67.4% after 100 cycles.

Scientists from French research institute CEA-Liten have identified hydrogen migration in doped selective layers as the primary driver of UV-induced degradation in silicon heterojunction solar cells. They have also found that combined light and thermal light-soaking treatments can partially restore performance and improve long-term UV stability.

U.S. scientists used density functional theory to reveal how sodium ions are stored in nanoporous carbon anodes for sodium-ion batteries, identifying dual ionic and metallic storage mechanisms within the pores. Their findings provide practical design guidelines to improve battery voltage, safety, and commercial viability for stationary energy storage.

WFES 2026 in Abu Dhabi underscored growing momentum for solar, storage, and C&I renewables across MENA, with batteries emerging as a key enabler for grid stability, agriculture, and data centers. Industry leaders pointed to Iraq, Libya, Yemen, and Saudi Arabia as key growth markets, highlighting rising interest in AI-driven data centers, solar-plus-storage solutions, and a broadening regional supply chain.

Silver prices hit a record $94.73/oz on January 19. Silver analyst Philip Newman tells pv magazine the metal could soon surpass $100/oz, increasing pressure on PV module manufacturers to reduce silver usage.

SoftBank Group is piloting AI-controlled cellular base stations powered by solar panels and a 3 kW wind turbine to reduce energy use while maintaining service quality. The system stores excess power in batteries and can automatically switch to the grid when needed.

Oxford PV CEO David Ward spoke with pv magazine about the prospects of its company and the perovksite-silicon tandem PV technology at the WFES event in Abu Dhabi. He said Oxford PV is expanding manufacturing beyond Germany while focusing on global licensing partnerships.

The launch of the new product suggests Tesla could renew its focus on residential solar and expand U.S. lease options with Powerwall.

The patent infringement case was related to an unspecified TOPCon solar cell technology.
