Technology and R&D

Fire caused by an electrical fault from an overheated arcing cable hit the solar panels at Europa Point Stadium in Gibraltar. Firefighters contained and extinguished the blaze within 20 minutes.

U.S. researchers developed a framework showing that wider spacing between solar PV rows can make agrivoltaic systems economically viable for large-scale mechanized farming. Their simulations in Colorado demonstrated that optimized row spacing maintains crop production while improving combined agricultural and energy revenues.

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.

Heat pumps are increasingly used for domestic hot water in Europe due to their efficiency and compatibility with solar power, but their lower operating temperatures can create conditions where Legionella pneumophila may grow if systems are poorly designed. Proper hydraulic design, temperature control, and periodic thermal disinfection ensure both high efficiency and safe, hygienic operation.

Toshiba has unveiled a PV management platform within its Spinex for Energy portfolio that enables real-time monitoring and O&M of multiple solar plants.
The system uses AI to track plant performance, detect faults, calculate capacity and PR metrics, automate reporting, and support troubleshooting.

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.

Nearly 20 years after the first perovskite solar cell was developed, its efficiency and durability are drawing interest from industries worldwide. The defense sector is among the most active, as rising geopolitical tensions drive record government spending to protect critical systems from disruption and attack.

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.
