EU funding ban on high-risk inverters, including Chinese suppliers, extends to BESS
The new policy has already applied, and impacts billions in funding from the European Investment Bank on renewable projects including standalone and co-located storage.
Japan reopens NEDO perovskite solar call with single-junction focus
Japan’s New Energy and Industrial Technology Development Organization (NEDO) has opened a supplementary call for proposals on mass production of next-generation single-junction perovskite solar cells, with submissions due by June 3.
Study finds ‘relatively good’ agreement in worldwide solar cell calibrations, but flags key differences in testing methods
An interlaboratory comparison across nine metrology institutes found generally good agreement in solar cell calibration under the World Photovoltaic Scale, but still revealed measurable differences in short-circuit current, voltage, and power due to varying methods and conditions.
Solar inverters can detect cyberattacks but no one sees the signal
A King Abdullah University of Science and Technology (KAUST) researcher whose lab has demonstrated up to 100% accuracy using a single hardware counter tells pv magazine that firmware-level detection of inverter attacks is technically viable – but today’s communication standards do not transmit the firmware‑integrity signal to operators.
Chinese PV Industry Brief: Longi, Trina Solar report losses
Longi says its 2025 revenue and losses declined year on year, while Trina Solar reports deeper full-year losses and margin pressure across its core module business.
20-month field tests show tracker-based bifacial PV outperforms fixed tilt counterparts with 13.5% higher ouput in desert enviroments
Qatari researchers found that bifacial 2P horizontal single-axis tracking PV systems in desert conditions produced up to 13.5% more electricity than fixed-tilt systems over long-term field testing in Qatar. The study also showed strong seasonal and technology-dependent performance, with tracker advantages varying with irradiance and weather conditions.
Inorganic perovskite solar cell based on tetraphenyl-porphine zinc interlayer achieves 82% fill factor
An international research team has proposed a perovskite solar cell architecture incorporating a thin tetraphenyl-porphine zinc interfacial layer to enhance surface potential, passivate defect states, and improve charge transport. The strategy leads to improved device efficiency and operational stability, enabling power conversion efficiencies exceeding 13%.
Australian researchers develop vapour-based manufacturing process for lead-free perovskite solar
Researchers at the University of Queensland have developed a scalable, lead-free perovskite solar cell manufacturing process that achieves record indoor-light efficiency while avoiding toxic materials and enabling flexible consumer electronics applications.
German solar module maker Soluxtec files for insolvency
Soluxtec has entered provisional insolvency proceedings as declining module prices and international competition continue to pressure European solar manufacturers. The company said it plans to restructure operations, maintain module deliveries, and preserve jobs while seeking investors.
Solar Manufacturing USA 2026 – production and technology at the heart of US solar
The upcoming Solar Manufacturing USA 2026 conference in Austin will focus on real U.S. solar manufacturing progress, shifting attention from capacity announcements to actual production, costs, yields, and technology choices across the full value chain. It will also examine how policy changes and tariffs are driving domestic expansion in ingots, wafers, cells, and modules, while highlighting competing technologies like back contact, heterojunction and TOPCon.
