Sodium‑ion batteries are emerging as a safer, lower-cost alternative to lithium‑ion, with a recent international study highlighting their competitiveness in stationary energy storage. The research shows that ongoing investment and supply-chain development could enable broader adoption within the next decade.

Researchers at SUPSI found that six Swiss PV systems installed in the late 1980s and early 1990s show exceptionally low degradation rates of just 0.16% to 0.24% per year after more than 30 years of operation. The study shows that thermal stress, ventilation, and material design play a greater role in long-term module reliability than altitude or irradiance alone.

pv magazine has spoken with silver analysts from Bloomberg and StoneX about the vertiginous growth of silver prices in recent weeks. They both agree that when prices rise too fast, investors’ behavior may change quickly. Meanwhile, the price of the precious metal has reached another all-time high today at $110 per ounce.

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.
