Chinese researchers have demonstrated organic solar cells with novel encapsulation and a protective boundary layer for improved stability and efficiency. The best-performing cell based on the new approach retained 94% of its initial energy conversion efficiency after standards-based moist heat testing for 1,032 hours of moist heat and over 200 thermal cycles. November 19, 2025 Valerie Thompson A research team in China has demonstrated organic solar cells (OSC) with a protective boundary layer and novel encapsulation that achieved high efficiency and improved stability. The best performing cell based on the new approach retained 94% of the initial energy conversion efficiency…
Scientists in the UK have compiled a new database of compressed air adiabatic energy storage projects. Using this data, they were able to determine the experience rate and identify the conditions under which the technology would be economically viable. According to their findings, costs have fallen by 15% since 2013. November 19, 2025 Lior Kahana A 250 kW / 1 MWh AirBattery system built by Augwind Image: Augwind A group of researchers led by Britain’s King’s College London has compiled a comprehensive database of adiabatic energy storage projects (A-CAES), collecting information on both operational systems and planned installations around the…
Energy storage developer Fullmark Energy announced the ITC transfer of $46 million to an industrial sector buyer for its operating 125 MW/290 MWh Redwood Projects portfolio. The transaction demonstrates the continued effectiveness of the Inflation Reduction Act in mobilizing private capital for renewable energy infrastructure. The strategic ITC transfer provides Fullmark Energy with greater financial flexibility to accelerate the development of additional energy storage while strengthening operations in the Redwood portfolio of four projects in Southern California. The transaction was completed following the portfolio’s commercial operation date (COD), announced on November 7, 2025. “This ITC transfer illustrates how the Inflation…

As universities expand outdoor education, off-grid solar furniture is emerging as a new class of campus infrastructure. November 19, 2025 Phoebe Skok By pv magazine USA Renewable distributed energy sources (DERs) are increasingly an important part of decarbonization and resilience strategies for college campuses. For students, they will also be charging points for laptops, lunch tables and study places. Solar-powered furniture, which combines tables, benches and shaded outdoor work stations with solar panels, batteries and device charging, is springing up on campuses across the country. Although many colleges and universities are pursuing ambitious goals to reduce carbon emissions, implementation of…
US researchers have developed a sodium-ion pouch cell that operates reliably at temperatures down to –100 C. The battery has been tested with simulated and real renewable energy sources, including wind and solar energy, and maintained stable performance in both laboratory and field conditions. November 18, 2025 Lior Kahana The research team and the field setup Image: Purdue University A research group led by scientists at Purdue University has fabricated a sodium-ion battery (SIB) pocket cell using ultra-low temperature compatible components and tested it under harsh conditions while connected to renewable energy sources. SIB technology is considered a more sustainable…
Floating solar panels are emerging as a promising clean energy solution with environmental benefits, but a new study shows that these impacts vary significantly depending on where the systems are deployed. Researchers from Oregon State University and the US Geological Survey modeled the impact of floating solar photovoltaic systems on eleven reservoirs in six states. Their simulations showed that the systems consistently cooled surface water and changed water temperatures at different layers within the reservoirs. However, the panels also introduced greater variability in habitat suitability for aquatic species. “Different reservoirs will respond differently based on factors such as depth, circulation…
The quality assurance provider reported that India-based Insolation Energy, Waaree Renewable Technologies and Solex Energy retained the top three positions in the Altmann-Z score-based quarterly ranking. The analysts noted that the number of companies with healthier scores rose from 9 to 11. November 18, 2025 Valerie Thompson Sinovoltaics, a Hong Kong-based technical compliance and quality assurance provider, has published its latest quarterly earnings report PV module manufacturer ranking reporttracking the Altmann-Z scores for 64 manufacturers from September 2022 to June 2025. Three Indian manufacturers are in the top three of the rankings this quarter: Insolation Energy, Waaree Renewable Technologies and…
Romania’s new €150 million ($173.8 million) municipal storage program could add 385 MW of capacity and, according to the government, coincides with the financing of one of the country’s largest standalone battery projects. November 18, 2025 Marija Maisch Image: Minister of Energy, LinkedIn By ESS news Romania has taken another bold step in expanding its battery storage fleet with the launch of a €150 million program for municipalities, which will add 385 MW of new battery capacity to the system. Energy Minister Bogdan Ivan attended a meeting this week with the Association of Romanian Municipalities (AMR), where he discussed the…
A wastewater treatment plant in the canton of Bern has been inaugurated with what dhp Technology claims is the world’s largest foldable rooftop solar installation to date. The 3.6 MW array includes several treatment basins, allowing the existing site to serve a dual purpose: ground-level wastewater treatment and overhead solar power generation. November 18, 2025 Sandra Enkhardt Part of the photovoltaic folding roof Image: dhp Technology AG By pv magazine Germany A 3.6 MW folding photovoltaic roof has been inaugurated at the Thunersee wastewater treatment plant in the Swiss canton of Bern.
