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.

China’s PV module prices are expected to hover around $0.12/W in the second half of 2026 as the removal of export VAT rebates, front-loaded demand, and persistent oversupply keep market sentiment volatile.

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.

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

The duties range from 53.3% to 57% for U.S. producers and from 2.4% to 48.7% for South Korean companies and will remain in force for a further five years.

A new Perspectives research study on the future of the global PV supply chain outlines how module prices, performance, and lifetimes could evolve over the next 25 years. The work reflects a collaboration among leading solar research institutions worldwide. One of the study’s authors, the director of the Fraunhofer Institute for Solar Energy Systems (ISE), told pv magazine that solar module and cell efficiencies could exceed 35% by 2050, with panel prices expected to drop by a factor of two.

France-based DOTSun has developed an on-site repair solution for solar panels with degraded backsheets, compatible with PA, PVDF, and PET types. The system uses a compact laminator to apply a protective film to the rear side of the module, reportedly restoring insulation and extending the service life of up to 2,000 panels per site.

The research group led by Professor Martin Green has not published yet Version 67 of the solar cell efficiency tables, due to production delays. Green, however, has accepted to comment on some of the results to be added in the upcoming edition.

Sunwafe says it has formally applied to reserve land in Asturias, Spain, for a 20 GW silicon wafer and ingot factory backed by Chinese capital, EIT InnoEnergy, and a €200 million ($232.6 million) Spanish government grant.

Toshiba Energy Systems & Solutions Corp. (Toshiba ESS) has started testing batteries and energy management solutions to stabilize electricity in remote Saudi Arabia through a hybrid wind-solar pilot project. The project will run until May 2028 to evaluate power- and energy-oriented batteries and optimize battery use.
