Modules & Upstream Manufacturing

IEA-PVPS Task 15 has launched its first modeling intercomparison exercise on coloured building-integrated photovoltaics (BIPV) and is inviting PV modelers and researchers to evaluate their methods using real-world performance data.

Fujiyama Power Systems has started production at its 1 GW solar cell manufacturing facility in Dadri, India, with all output intended for in-house use to strengthen supply-chain security and support domestic content programs.

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.

Halocell Energy is set to benefit from the development of a sovereign supply chain for high-purity precursors to perovskite after signing a memorandum of understanding with Queensland advanced materials company Lava Blue.

Researchers from KAUST, TU Delft, and LMU Munich have improved the performance of monolithic perovskite-silicon tandem solar cells by modifying the physical structure at the front of the bottom heterojunction solar cell.

The Japan Photovoltaic Energy Association (JPEA) has released a voluntary reference guide to support adoption of vertical bifacial PV in Japan, outlining design, performance, and compliance considerations for projects in snow-prone, high-latitude, and space-constrained conditions.

China-based PV equipment supplier Ideal Energy (Shanghai) Sunflower Semiconductor has completed an AI-enabled pilot line for ultra-thin, flexible heterojunction (HJT) solar cells, targeting lightweight power systems for space and near-space applications.

Rising silver prices are pushing PV manufacturers toward copper-based metallization, with DK Electronic Materials targeting 2026 for large-scale deployment of high-copper paste solutions, while Fraunhofer ISE warns efficiency trade-offs remain unacceptable.

Researchers in Spain have tested the erosion resistance of common galvanized coatings using both free-falling sand and forced-air sand-impingement methods. The study found that continuously galvanized steel coatings showed the lowest erosion rates, outperforming HDG and Zn-Al-Mg coatings.

The U.S. federal patent office rejected separate challenges from JinkoSolar, Canadian Solar and Mundra Solar to invalidate intellectual property that First Solar claims is fundamental to the manufacturing of crystalline silicon solar cells.
