Array Technologies has doubled the flex capability of the OmniTrack terrain-following tracker. The updated product is expected to ship later this year.

Scientists in India have assessed the accuracy of three widely-used simulation tools in predicting the performance of a floating PV plant. The research also found the array is helping to reduce surface water evaporation.

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.

The Danish company said its ISOSun Pro Solar Simulator has 20 independently tunable LED wavelengths. It delivers intensities of up to 7 suns.

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.

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.

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.

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.

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.
