New UNSW research found that about 20% of solar modules in large PV plants degrade much faster than expected. They recommend holistic strategies such as robust materials, advanced designs, and proactive monitoring to decouple degradation pathways and prevent cascading failures.

A Husqvarna researcher developed a fast, interpretable PV hotspot-detection method using IR thermography and Lab* color-space features instead of heavy neural networks, achieving up to 95.2% accuracy with shallow classifiers. The lightweight system works in real time on drones or edge devices and could save 17,620 kWh and 8.9 tons of CO₂ annually by improving fault detection in solar panels.

France-based DOTSun has developed an on-site repair solution for solar panels with degraded backsheets, compatible with PA, PVDF, and PET types. The system uses a compact laminator to apply a protective film to the rear side of the module, reportedly restoring insulation and extending the service life of up to 2,000 panels per site.

New research shows how modern technical standards, combined with broader regulatory and grid reforms, are essential to ensure system reliability in the Indonesian electricity system as renewable capacity grows.

Researchers led by Michael Grätzel at the Ecole Polytechnique Federale de Lausanne in Switzerland have recently led efforts to improve perovskite optoelectronic properties using small-radius rubidium ion chemistry to enable more stable and efficient perovskite solar cells.

A Malaysian research team proposed new concepts such as cowvoltaics, sheepvoltaics, goatvoltaics, veggievoltaics, fruitvoltaics and fishvoltaics to better define the diverse applications of photovoltaics in dual land use. Their review outlines four main categories – livestockvoltaics, crop-based agrivoltaics, aquavoltaics, and zoovoltaics – and presents several business cases.

In two separate projects Japan-based Kyuden Mirai Energy and Nissan Motor are demonstrating the use of flexible, glass-free chalcopyrite PV panels provided by PXP Corporation.

A University of Exeter team has tested single-axis tracking systems for floating solar across 12 UK sites, finding azimuthal tracking delivers the largest energy gains and lowest levelized cost of energy (LCOE).

Scientists have simulated a residential building based on a real double-story house in the United Kingdom, combining rooftop agrivoltaics with onsite hydrogen production. Electricity generated by the solar system is used to produce hydrogen, which is then supplied to a hydrogen vehicle and insulated gasochromic smart windows.

Researchers in Norway investigated the melting behavior of silicon kerf agglomerates under different atmospheres and temperatures to improve recycling for solar-grade silicon. They found that vacuum melting enhances deoxidation and produces a homogeneous, oxide-free melt, while agglomerate size has little effect on melting behavior.
