Optimizing solar EV stations for maximum impact
A new report from the International Energy Agency Photovoltaic Power Systems Programme (IEA PVPS) Task 17 outlines how photovoltaic systems can be effectively integrated with electric vehicle charging infrastructure through optimized sizing, intelligent control, and site-specific design.
CEA-Ines, 3Sun build heterojunction solar modules based on UV downshifting
The new heterojunction solar module concept is based on co-extruded EVA/POE/EVA (EPE) encapsulant with UV downshifting (UV-DS) films, which convert harmful UV light into blue light, protecting cells and slightly boosting short-circuit current by 1.5–1.75%.
Hybrid perovskite solar cell generates power from sun and rain
Researchers at ICMS in Seville have developed a hybrid perovskite solar cell that generates electricity from both sunlight and raindrops, using the photovoltaic and triboelectric effects. A fluorinated CFₓ polymer layer enables water resistance, triboelectric energy harvesting, and high light transparency without reducing solar cell efficiency.
How to address imbalance datasets in solar panel dust detection
Researchers from South Korea improved solar panel dust detection by using SMOTE and stable diffusion (SD) augmentation, with SD boosting detection accuracy from 76.5% to 98.9% while preserving spatial realism.
Iraq slashes solar import tariffs to 5%
The Iraqi Customs Authority has cut customs duties on solar energy systems from 33% to 5% – covering PV panels, inverters, cables, and lithium batteries – to accelerate solar adoption, following financing support from the Central Bank of Iraq.
South Korea eases solar siting rules to cut permitting delays for PV projects
South Korea has passed legislative amendments to limit the ability of local authorities to impose separation distances on solar projects, removing a major permitting barrier for PV developers.
SERIS builds 22.1%-efficient perovskite-silicon tandem solar cell based on double-sided polysilicon layers
SERIS researchers developed a 16-cm² perovskite-silicon tandem solar cell with a double-sided TOPCon bottom cell, enhancing passivation, reducing recombination, and increasing voltage and fill factor.
CHN Energy switches on 2 GW solar plant at coal-mining subsidence area
The PV facility transforms a coal-subsidence zone into one of China’s largest utility-scale solar and transmission hubs. It is part of a 6 GW solar cluster, of which 4 GW are now operational.
PV-assisted heat pump prototype with dual condenser reaches 7.59 coefficient of performance
Researchers in Spain have developed a dual-condenser air-to-water heat pump that shifts domestic hot water production to daylight hours, maximizing PV self-consumption. The prototype boosted solar energy use from 9.9% to 55.5% and achieved a peak coefficient of performance of 7.59 under PV-assisted operation.
PV curtailment surges in France as grid adapts to rising solar output
French grid operator RTE says almost 3 TWh of renewable energy was curtailed in 2025, driven by higher solar output and more frequent negative-price market periods.
