US expert panel examines PV Hazard Control rules and UL 3741 changes
US industry experts trace the evolution of PV rapid shutdown rules and outline how recent updates to UL 3741 are reshaping compliance pathways for rooftop and commercial solar in the United States.
Solar generates record 13% of EU electricity in 2025
EU solar generation increased by over 20% for the fourth year running in 2025, with its share in the energy mix surpassing coal and hydro. For the first time in history, solar and wind generated more energy in the EU than fossil fuels.
Self-assembling molecule for organic solar cells
A research team from Osaka Metropolitan University have developed a donor-acceptor-donor molecule that can spontaneously self-assemble into nanoscale structures and offer a more stable route to built-in p/n heterojunctions in organic solar cells.
Scientists build tin lead perovskite solar cell with 24.07% efficiency
A Chinese-Swedish research team has boosted the performance of tin-lead perovskite solar cells by modifying additives and post-treatment processes. The device also demonstrated improved stability, retaining 60% of its initial efficiency after 550 hours at 85 °C under maximum power point conditions.
Chinese battery makers scale up from 314 Ah to 500 Ah-plus LFP cells
China’s leading stationary storage battery manufacturers are accelerating the rollout of 500 Ah-plus lithium iron phosphate (LFP) cells, betting that larger formats can cut system complexity and lift energy density in 6 MWh-class containers, even as safety, yield, and standardization challenges intensify.
China TOPCon solar module prices climb over 30% since mid-December
In a new weekly update for pv magazine, OPIS, a Dow Jones company, provides a quick look at the main price trends in the global PV industry.
‘An immediate transition to copper is technically and economically feasible’
With silver prices rising, more large solar manufacturers are expected to switch to copper for cell metallization. Radovan Kopecek of ISC Konstanz tells pv magazine that he expects the entire industry to follow. Ning Song of the University of New South Wales says a small efficiency tradeoff may be acceptable if the cost savings are significant and do not introduce new reliability risks.
US, Europe on track for 2030 solar goals despite pipeline gaps
A report from McKinsey and Company says the relative ease of building out solar projects means the U.S and Europe are likely to meet their end-of-decade deployment targets, despite current pipeline gaps of around 205 GW and 181 GW.
Austria’s Andritz to supply South Korean 500 MW pumped storage power plant
Austrian engineering group Andritz has signed a deal to supply the pump turbine units for a 500 MW pumped storage plant in South Korea, the country’s first new pumped storage project in over a decade.
Solar Steel presents new 2P single-row solar tracker
Spanish tracker manufacturer Solar Steel has introduced an upgraded 2P single-row tracker designed to simplify assembly, improve standardization, and support deployment on complex terrain, including agrivoltaic projects.
