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.

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.

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.

Using a bird’s structural-color trick to color solar modules A scientific team had colored PV modules using quasi-ordered photonic pigments rather than conventional absorbing dyes. The technique was inspired by blue feather birds. The colored PV modules exhibited efficiencies that represent more than a 50% improvement over conventional pigments.
