Perovskite tandem PV for agrivoltaics
Researchers evaluated “farm-to-fork” life-cycle impacts of agrivoltaic lettuce systems using perovskite–silicon and perovskite–perovskite tandem PV, comparing them with conventional silicon PV across major US growing regions. The study finds that integrating advanced tandem solar with farming can reduce irrigation demand and significantly cut greenhouse gas emissions—potentially offsetting up to 30.9 million tons of CO₂ and saving around 8.4 billion m³ of water annually under favorable conditions.

Chinese scientists improve kesterite solar cell efficiency with potassium fluoride
A Chinese research team improved kesterite solar cell efficiency using potassium fluoride treatment to optimise absorber quality and interface properties. The best device reached 8.04% efficiency, with gains driven by reduced interface defects and improved carrier management.

Stabilising perovskite solar cells with chlorine
Researchers have managed to bypass the formation of a yellow phase during the degradation of formamidinium lead iodide cells. They did so by tailoring the formation and degradation pathways with specific additives. Researcher: The additives stabiliSe the system.
Solar module recycling based on oxidative liquefaction
Researchers have developed a low-temperature, hydrogen peroxide-mediated oxidative liquefaction process to recycle end-of-life solar panels by selectively breaking down polymers into useful chemical feedstocks. The proposed method reduces energy consumption, eliminates hazardous solvents, and minimises landfill waste compared to traditional recycling techniques.
How to prevent stray voltage from harming livestock in PV-equipped dairy farms
Stray voltage is unwanted electrical potential differences in sheds that can cause small shocks to livestock, especially dairy cattle, through damp floors, metal equipment, and water systems, leading to stress and reduced productivity, and in some cases even to death. While PV systems are sometimes blamed, experts told pv magazine that the real causes are faulty or poorly designed grounding and electrical infrastructure, and that proper equipotential bonding is key to prevention. With attentive design, these risks to animal health can be avoided.

AI model uses cloud type and cover to predict solar power swings
A machine-learning model uses cloud type and cloud cover to predict rapid changes in surface solar irradiance, including short-term “ramp” events that affect grid stability. When tested across 15 global sites, it showed strong generalisability, with most locations matching or exceeding the original model’s predictive performance, though extreme climates performed less consistently.
Study finds PV plants reshape land surface conditions, reducing wind speed and increasing soil moisture
A China-based research team conducted a systematic review and meta-analysis of 147 studies on how solar PV systems alter land surface processes, covering 609 installations worldwide and 11 key climate variables.
