Modules & Upstream Manufacturing

Researchers in Japan have achieved a 12.28% efficiency in a copper gallium selenide solar cell, the highest reported for indium-free wide-bandgap chalcogenide absorbers in the 1.65–1.75 eV range. The device uses aluminum-engineered films with a back-surface field and optimized cadmium sulfide buffer layers to enhance voltage, reduce recombination, and improve overall performance.

Solar manufacturer Swift Solar has acquired the heterojunction technology (HJT) intellectual property and manufacturing assets of Meyer Burger to establish domestic cell production.

GlobalData says Russia added an estimated 100 MW of solar last year, taking total installed solar to around 3.1 GW. The consultancy is forecasting annual additions of about 200 MW over the next ten years, taking the country’s cumulative solar capacity to 5.3 GW by 2035.

Researchers at Germany’s Fraunhofer FKIE institute developed PowerRange, a virtual simulation platform that helps power grid operators safely test cybersecurity measures and respond to realistic cyberattacks. The platform supports both traditional and renewable grids, offering immersive training across IT, OT, and control systems while highlighting the importance of coordination, communication, and practical defense strategies.

Eastman Auto & Power has started production at an 800 MW solar panel factory in the Indian state of Haryana.

Researchers from Australian National University and Longi used photoluminescence imaging to analyze dopant distributions in RCz-grown silicon wafers doped with antimony, phosphorus, and gallium, finding highly uniform radial concentration profiles suitable for high-efficiency solar cells. The study also found that antimony-doped wafers provide more stable axial doping along the ingot, highlighting their potential for next-generation photovoltaic manufacturing.

The Chinese manufacturer said its new back-contact module delivers up to 545 W and over 25% efficiency in a compact rooftop format for residential, C&I, and off-grid applications.

German manufacturer Ehret has launched SolarSlide, a sliding shutter with integrated PV modules developed with the Fraunhofer Institute for Solar Energy Systems (Fraunhofer ISE). It provides solar shading while generating electricity for residential and commercial facades.

The Danish company says its new product is ideal for small to medium-sized solar cell testing. It can simulate light conditions in the 390–700 nm range.

Africa has abundant sunlight, arable land, and innovative farmers, and agrivoltaics offers a long-term strategy to boost food security, climate resilience, and energy access simultaneously. Success depends on coordinated policy, inclusive community engagement, and patient, innovative finance to build a viable, scalable market.
