European Commission proposes Made in EU requirements for solar inverters, cells
The Industrial Accelerator Act says solar projects awarded through public procurements or other public support schemes would need to feature Europe-made solar inverters and cells within three years after the act becomes law. For battery energy storage systems, similar requirements would be introduced using a phased approach from one year after the act enters force.
Heliup raises €16 million to scale lightweight solar panel production
French solar manufacturer Heliup has raised €16 million ($18.6 million) to scale production of lightweight solar panels designed for commercial and industrial rooftops with low load-bearing capacity.
Korean researchers build back-contact perovskite solar cells with lower recombination losses
The research team developed the perovskite solar cell with a spin-coated bilayer tin oxide electron transport layer that boosts charge extraction, achieving a 4.52% efficiency and improved stability.
Oleic acid anti‑soiling coating for solar modules
Researchers in Türkiye have developed a passive anti-soiling coating for PV panels using oleic acid–modified aluminum oxide nanoparticles applied via spray coating. Laboratory and field tests showed the coating reduced dust accumulation and initially boosted daily energy output, though performance declined under prolonged environmental stressors.
TCL Sunpower presents shingle TOPCon solar panels for rooftop PV
The Chinese manufacturer expanded its P Class portfolio with two new shingled-module series for residential and commercial rooftop installations. Both lines feature high-density, multi-busbar shingled cells for improved shade tolerance and long-term reliability with 30-year warranties.
Trina Solar unveils 485 W TOPCon PV panel with 24.3% efficiency
The Chinese manufacturer has launched its third-generation Vertex S+ G3 dual-glass TOPCon modules for residential and commercial applications. The new products feature upgraded module architecture and a temperature coefficient if -0.26% per C.
Optimizing solar EV stations for maximum impact
A new report from the International Energy Agency Photovoltaic Power Systems Programme (IEA PVPS) Task 17 outlines how photovoltaic systems can be effectively integrated with electric vehicle charging infrastructure through optimized sizing, intelligent control, and site-specific design.
Group Surya commissions 500 MW G12R module line in India
Group Surya has launched a 500 MW G12R solar module production line in Odisha, India, with plans to double capacity to 1 GW within months.
CEA-Ines, 3Sun build heterojunction solar modules based on UV downshifting
The new heterojunction solar module concept is based on co-extruded EVA/POE/EVA (EPE) encapsulant with UV downshifting (UV-DS) films, which convert harmful UV light into blue light, protecting cells and slightly boosting short-circuit current by 1.5–1.75%.
Hybrid perovskite solar cell generates power from sun and rain
Researchers at ICMS in Seville have developed a hybrid perovskite solar cell that generates electricity from both sunlight and raindrops, using the photovoltaic and triboelectric effects. A fluorinated CFₓ polymer layer enables water resistance, triboelectric energy harvesting, and high light transparency without reducing solar cell efficiency.
