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.
Satellite breakthrough enables accurate panel-scale temperature mapping for solar farms
A Chinese research team has developed a scene-aware panel surface temperature (PST) retrieval model for utility-scale photovoltaic (PV) plants using MODIS thermal infrared satellite data. The method corrects for mixed-pixel effects, array geometry, and PV-specific directional emissivity to enable accurate panel-scale temperature estimation from space.

Pseudo-planar heterojunction organic solar cell achieves world record efficiency of 20.21%
Scientists have created pseudo-planar heterojunction organic solar cells with one of the highest efficiency scores ever for that structure. To do so, they had to overcome solvent-induced swelling and erosion of the donor. Their solution: a novel interfacial buffering strategy.
Home cooling panel based on PV and waste cooking oil
Researchers have designed a system that incorporates PV power generation, thermoelectric cooling, and latent heat storage using waste cooking oil. They have simulated an optimized it using an array of models. Results suggest that a single panel can deliver approximately 6–15 kWh/day of cooling.
Solar module cooling tech based on perforated fins
Researchers in Algeria simulated perforated hexagonal-fin heat sinks to improve PV cooling performance using CFD analysis. The best design reduced cell temperature by up to 20.93% and increased efficiency while maintaining high thermal performance under forced convection.

Foam-based floating PV system for cold climates
Researchers at Canada’s Western University demonstrated that a foam-backed floating solar PV system with an air-bubbler can operate effectively through freezing winters, keeping ice at bay with minimal energy use. The system produced up to 2.7% more annual energy than conventional PV models, reduced water evaporation, and showed strong economic potential with a payback period of about 4.2 years under high electricity prices.
Chinese scientists improve kesterite solar cell efficiency with potassium fluoride
A Chinese team improved kesterite solar cell efficiency using potassium fluoride (KF) treatment to optimize absorber quality and interface properties. The best device reached 8.04% efficiency, with gains driven by reduced interface defects and improved carrier management.
Study finds ‘significant’ agrivoltaic potential in Austria
A techno-economic study in Austria evaluates agrivoltaic systems using a spatial simulation framework that jointly models solar power generation and crop production under current and future climate conditions. Results show ground-mounted PV delivers the highest electricity output and profits, while agrivoltaics reduce agricultural losses but offer only modest climate adaptation benefits compared to PV-only systems.
