AI-assisted method maps PV module losses from a single luminescence image
An international research team has developed an AI-assisted method that quantifies PV module power losses from a single luminescence image. The approach achieved an overall error of about 0.5% in tests on 300 field-retrieved modules and was demonstrated using drone-based imaging at a 186 kW solar farm.

Scientists build 17%-efficient semi-transparent perovskite solar cell based on sputter-resistant aluminum oxide layer
Researchers replaced the conventional 20 nm SnOâ‚“ buffer layer with just 3 nm of ALD-deposited AlOâ‚“, which protected inverted perovskite cells from ITO sputtering damage while maintaining efficient charge extraction. The resulting devices achieved efficiencies above 17% in semi-transparent cells and 26% in perovskite-silicon tandems, while reducing material use and fabrication time.
New electrode design increases battery energy density by up to 15%
Fraunhofer ISE and its partners have developed thicker electrodes that could increase battery cell energy density by 10% to 15% without adding weight. The PFAS-free, solvent-free concept has been demonstrated in lithium-ion, sodium-ion, and zinc-ion cells and is designed for cost-effective mass production.

Scientists turn end-of-life PV silicon into high-value silicon nitride
Researchers have developed a method to upcycle silicon recovered from end-of-life PV modules into high-value silicon nitride. The process achieved recycled silicon purity of 99.95% through optimised milling, acid etching, and sedimentation before nitridation.

Italian scientists build glass-free flexible silicon PV modules via roll-to-roll
Researchers have developed a glass-free flexible crystalline-silicon module architecture based on commercial IBC cells and a PET/EVA stack manufactured via roll-to-roll hot lamination. The 2 × 2 mini-module retained 96.12% of its initial efficiency after 672 hours of outdoor testing at a fixed bending radius of 150 mm.
Australian researchers develop automated screening method for second-life PV modules
An automated I-V screening method identified 58.1% of decommissioned PV modules as suitable for second-life use, with those passing the screening showing a median estimated residual useful life of around 12 years. However, about 14% of modules that passed combined I-V and EL screening failed wet-leakage tests, highlighting the need to assess insulation safety separately from performance.
Researchers model 1,708 pathways for global PV waste recycling
New research finds that optimized, outsourced PV recycling could cut up to 3.32 billion metric tons of CO2 equivalent and generate as much as $935.5 billion in net benefits by 2060. The researchers say declining subsidies could help distribute these benefits more evenly across regions while supporting recycling until it becomes economically viable.
