The system enables measurements under controlled irradiance, spectrum, and temperature conditions. It can combine 0.4% spatial irradiance uniformity, 500 ms illumination pulses, and dynamic I-V acquisition to accurately test high-capacitance photovoltaic modules in a single pulse, according to Ciemat.

In 2025, back-contact solar modules from Aiko Solar and Longi accounted for more than 50% of the Swiss market, driven by strong demand for high-efficiency rooftop PV systems, according to a new report by Eturnity and the Bern University of Applied Sciences.

Austrian researchers conducted a techno-economic analysis of agrivoltaic systems and found that 5%–16% of the country’s cropland would be required to meet its solar electricity targets.

An international research team developed CyberSentry, a software framework using advanced deep learning and optimization techniques to enhance cybersecurity in SCADA systems for power plants and critical infrastructure. It combines feature selection, hybrid anomaly detection, and dynamic parameter tuning to detect diverse cyberattacks with 99.5% accuracy while minimizing false alarms.

The LEEMONS project is researching nanostructured silicon that uses low-energy electron multiplication (LEEM) to allow one high-energy photon to generate multiple electrons, reducing energy losses in solar cells. By creating ultra-thin amorphous silicon layers inside crystalline silicon via ion implantation, the scientists aim to boost solar cell efficiency beyond the Shockley–Queisser limit while keeping compatibility with existing manufacturing methods.

Sigenergy has launched a 166 kW IP66-rated inverter for C&I solar and storage offering nine MPPT trackers and flexible AC/DC connections. The launch coincided with the opening of its Nantong Smart Energy Center, a 136,000 m² facility for R&D, manufacturing, and global delivery.

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.

A new global dataset of 119 energy-sector cyber incidents from 2022–2024 shows EU and BRICS countries, followed by the US, are most affected. Attacks targeted power, oil, gas, and nuclear infrastructure, driven by both financial and political motives, with diverse threat actors involved.

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.
