New single-diode model tackles recombination losses in solar cells
UNSW researchers have developed an intrinsic-adjusted single-diode model that explicitly accounts for radiative and Auger recombination, improving I–V curve accuracy and reducing root mean square error by up to a factor of three. The model is claimed to better predict performance near open-circuit voltage and maximum power point.
Idemitsu switches on 2 MW of solar above rice paddy
Japanese petroleum company Idemitsu Kosan has announced its 2 MW agricultural solar power plant, installed 3.8 meters above a rice paddy, has begun operating. The project features a community-based model that returns a portion of the profits from power generation to the farmers.
Anti-glare film enables PV system at Brussels Airport
Warehouses De Pauw (WDP) has installed an 8.5 MW solar system at a warehouse near Brussels-Charleroi Airport, equipping roughly 40% of modules with Phytonics anti-glare film to prevent air traffic disruption while maintaining near-full energy output.
Space-based solar could be competitive by 2040, UK government finds
Investment and support could make small-scale space-based solar power (SBSP) viable, with potential for electricity generated in orbit to participate in UK contracts for difference (CfD) scheme according to new report. Launch costs have biggest impact on levelized cost of electricity (LCOE), according to analysis.
The effects of solar module elevation on ground-mounted PV
Scientists in Hungary found that ground-mounted PV modules at an intermediate elevation of 1.1 m achieve the highest efficiency and power output due to improved airflow and reduced cell temperature. Their study also estimated a levelized cost of electricity of $0.0843/kWh and 577.78 kg CO₂ mitigation over 25 years, while noting results are specific to concrete surfaces.
AI can now predict solar cell efficiency from wafer quality
Korea University researchers have developed a machine-learning framework that predicts solar cell efficiency from wafer quality, enabling early wafer screening and optimized production paths. Using over 100,000 industrial data points, the approach combines predictive modeling, process optimization, and explainable AI to support photovoltaic manufacturing.
Bert Thin Films launches copper paste for backside solar cell metallization
The U.S. startup has introduced a screen-printable copper paste for backside solar cell metallization that can be fired in air and co-fired with standard silver frontside pastes using conventional manufacturing processes. Tested on TOPCon cells, the paste contributed to achieve a 25% efficiency and passed 2,000-hour damp heat testing.
Centrotherm launches new high-volume TOPCon PECVD tool
The Germany-based PV thermal process equipment and technology provider has launched c.Plasma Q Max to process up to 10,000 wafers per hour in high-volume TOPCon solar cell manufacturing lines.
Long-term trade-offs of agrivoltaics on pear farming
A four-year study found that overhead solar panels in an Australian pear orchard reduced sun and hail damage but decreased fruit yield and blush coloration. While energy production and tree stress resilience improved, the findings highlight trade-offs for agrivoltaic systems, with potential applicability to other fruit crops like apples and cherries.
Global-warming-induced degradation could raise rooftop solar LCOE by up to 20%
A global study finds climate change will sharply increase high-temperature risks, accelerate degradation, and raise costs for rooftop PV, with economically disadvantaged regions hit hardest. Researchers warn current IEC standards underestimate future risks, urging urgent updates to avoid stranded assets and rising electricity costs.
