On November 26 RWE commissioned Stoneridge Solar to deliver homegrown energy to Milam County, Texas. The project includes 200 MW of solar energy and 200 MWh of battery storage, strengthening the state’s supply of reliable, cost-competitive electricity. “Stoneridge Solar is a great example of the power of local partnership and the positive role energy projects play in economic stimulation. We are helping Texas and the nation secure their energy future with scalable, homegrown energy while delivering meaningful benefits to communities across America’s heartland,” said Andrew Flanagan, CEO of RWE Clean Energy. Stoneridge Solar created more than 200 construction jobs and…

Korean researchers revealed that efficiency losses in heterojunction solar cells are due to two coexisting types of defects: dangling bonds and weak silicon-silicon bonds. Their findings explain how passivation of hydrogenated amorphous silicon helps reduce these defects and improve cell performance. November 27, 2025 Emiliano Bellini A group of scientists led by the Korea Institute of Energy Research (KIER) has conducted extensive research on defects in silicon heterojunction solar cells and found a direct correlation between these defects and passivation quality. “Conventional defect analysis in solar cells and semiconductor devices has largely focused on measuring defect concentration,” said the study’s…

The UK government has published its response to the electric vehicle (EV) charging section of its consultation on solar carports, showing broad industry support for streamlining the deployment of EV infrastructure, while the core question of the solar mandate remains unanswered.The government’s response relates to part 2 of the call for evidence, which focused on EV charging infrastructure and planning policy. The consultation, that DESNZ launched in Maysought views on mandating solar canopies on new car parks alongside reforms to electric vehicle charging planning processes.Of the 125 responses received during the consultation period from 7 May to 18 June 2025,…

The Chinese manufacturer says the German Institute for Solar Energy Research Hamelin (ISFH) has independently verified the result. November 27, 2025 Vincent Shaw Chinese solar module manufacturer JinkoSolar has set a new world record for the efficiency of n-type TOPCon solar cells, with a range of 27.79%. The performance was independently verified by the German Institute for Solar Energy Research Hamelin (ISFH). In June, the company had already set a record for the same 182mm n-type cell type with an efficiency of 27.02%, certified by China’s National Photovoltaic Industry Measurement and Testing Center (NPVM). The company said the new record…

A financing program from the Palestine Investment Fund and the European Union has helped install solar systems at Jerusalem-based companies and projects, resulting in annual electricity cost savings of approximately €250,000. November 27, 2025 Patrick Jowett Jerusalem, Israel Image: Lucija Ros/Unsplash A green financing initiative has helped install solar systems for companies based in India The Palestinian neighborhoods of Jerusalem. First announced in 2022, the Jerusalem Green Energy and Sustainability Financing Program is managed by the Palestine Investment Fund (PIF) in partnership with the European Union. The two entities donated approximately €2.4 million ($2.8 million) to the program, which was…

The Italian renewable energy company said it will validate Swift Solar’s 28% efficiency perovskite-silicon tandem technology in a utility-scale project. November 26, 2025 Ryan Kennedy By pv magazine USA Swift Solar has announced a partnership with solar developer Plenitude for utility-scale pilot testing and evaluation of long-term supply arrangements. Plenitude is a company controlled by Italian energy giant Eni that aims to achieve 15 GW of renewable capacity by 2030. Eni Next, the venture capital arm of Eni, is a strategic investor in Swift Solar. The partnership represents a milestone in the commercialization of perovskite technology for utility-scale solar energy.…

Eighteen California lawmakers submitted a joint letter on Nov. 25 to the California Public Utilities Commission (CPUC) about delays in turning on solar and storage customers at the state’s two largest utilities. The letter urges the CPUC to hold Pacific Gas & Electric (PG&E) and Southern California Edison (SCE) accountable for repeatedly missing state-mandated timelines. “Californians deserve an energy system that accelerates our climate goals – not one that continues to delay,” said Assembly Member Dawn Addis (Morro Bay). “We are leading the way on clean energy, but PG&E and SCE must stop slowing us down. Every missed deadline costs…

According to the Ministry of Economy and Finance, South Korea has allocated KRW33.6 billion ($22.8 million) to R&D in perovskite-silicon tandem solar technology with the aim of commercializing 28% efficient modules by 2030. November 26, 2025 Emiliano Bellini A perovskite-silicon tandem solar cell Image: KAUST South Korea’s Minister of Economy and Finance Koo Yun-cheol this week announced a KRW33.6 billion plan to help the domestic PV industry develop commercial perovskite-silicon tandem solar products by 2030. The plan is part of a broader plan aimed at the development of new construction high-voltage direct current (HVDC) technologies, as well as small nuclear…

Researchers in the United States have developed a photonic curing technique that uses laser sintering to quickly heat and harden copper pastes on temperature-sensitive solar cell substrates without causing thermal stress. The process reportedly produces dense, low-porosity copper layers with strong adhesion to indium tin oxide, achieving low bulk and contact resistance. November 26, 2025 Emiliano Bellini Researchers at the University of Central Florida in the United States have developed a photonic curing technique that reportedly improves the copper (Cu) metallization of solar cells by reducing Cu oxidation. “We have We have already made great progress in achieving cell efficiencies…
