The two-terminal perovskite-silicon tandem solar cell was fabricated via a chemical polishing method that selectively removes residual lead(II) iodide from the perovskite film in the top cell. This focused interface engineering improved uniformity and stability, enabling a certified efficiency of 31.71% and improved long-term performance. December 5, 2025 Emiliano Bellini A group of researchers led by China’s Northwestern Polytechnical University has developed a two-terminal (2T) perovskite-silicon tandem solar cell via an interface engineering strategy that removes residual lead(II) iodide (PbI2) from the wide bandgap perovskite cell without damaging its lattice. PbI2 formation in wide band gap perovskite solar cells arises…
An international team of researchers has completed a preliminary techno-economic study on the global potential for offshore floating PV (OFPV). The results provide benchmarking of project costs, country-specific economic assumptions and a global assessment of the levelized cost of electricity (LCOE) for offshore solar. December 5, 2025 Valerie Thompson An international team led by researchers from the Australian environmental and energy focused unit of RINA Consulting, part of Italy-based RINA, has analyzed offshore FPV (OFPV) resources worldwide based on technical feasibility, energy production and costs in an effort to provide estimates on suitable locations, costs and energy generation potential. The…
The US-based manufacturer has completed certification of its latest glue-free, fluorine-free backsheet. December 5, 2025 Valerie Thompson US-based solar materials manufacturer Endurans Solar has announced its new HP D15T transparent backsheet for utility-scale bifacial projects. “Our unique U.S.-made backsheets provide domestic module manufacturers with improved supply chain stability and give developers the ability to increase their domestic content ratio, enabling a critical strategic advantage for projects targeting Inflation Reduction Act (IRA) tax credits and U.S. government procurement requirements,” said Nate Coleman, CEO of Endurans Solar, in a statement. The adhesive-free, fluorine-free backing, called HP D15T, has completed IEC 62788-2-1:2023 certification…
Global energy storage shipments rose 84.7% in the first three quarters of 2025, with Tesla and Chinese manufacturers leading the way, InfoLink says. December 5, 2025 Vincent Shaw By ESS news InfoLink’s latest rankings, drawn from the energy storage supply chain database, show that global ESS deliveries reached 286.35 GWh in the first and third quarters of 2025, with volumes exceeding 100 GWh in a single quarter for the first time in the third quarter. Market concentration remained high, with the top ten suppliers (CR10) accounting for roughly 60% of shipments, indicating that a clear leading cohort has emerged, even…
Swedish independent energy producer Alight has completed a 215 MW solar project in Lolland, southern Denmark. Construction of the Lidsø solar park started in the summer of 2024. December 5, 2025 Emiliano Bellini Alight has switched on a 215 MW solar farm – billed as Denmark’s second largest to date – in the southern municipality of Lolland. Construction of the Lidsø solar park started in the summer of 2024. The plant, developed and built by Denmark-based European Energy, will supply electricity The Danish State Railways (DSB) has entered into a long-term power purchase agreement (PPA), Alight said in a statement.…
The Japanese conglomerate has deployed its Panasonic HX hydrogen solution at its Munich factory. The system uses an AI-based power management system that reportedly eliminates the need for battery storage. December 5, 2025 Emiliano Bellini Panasonic has announced that it has started testing its Panasonic HX hydrogen energy solution at its office in Munich, Germany. The Panasonic HX platform typically consists of a renewable energy generator, Panasonic PH3 fuel cells and battery storage. However, for the German project, batteries were deemed redundant thanks to an AI-based energy management system (EMS) that performs real-time fuel cell control in response to fluctuations…
Ameresco has completed a solar energy portfolio that includes seven schools in California’s Orange Unified School District (OUSD). Ameresco developed the rooftop solar PV systems and carport for the district, located on four elementary school campuses, one middle school campus and two high school campuses. As part of the power purchase agreement, Ameresco will own and maintain the solar energy systems, and OUSD will purchase the power generated by each system at a fixed rate for the next 25 years. This flat rate allows OUSD to capture energy savings, insulate them from any fluctuations in energy prices and guarantee savings.…
A research team in India developed a passive cooling method for solar panels using a thin, stagnant layer of seawater placed over the module surface. Tests showed that while a thick layer of water greatly reduced energy production, a thin layer of 5 mm reduced module temperatures and increased daily energy generation by as much as 8.86%. December 5, 2025 Lior Kahana A research team led by the Indian Institute of Petroleum and Energy (IIPE) has developed a new passive evaporative cooling system with solar panels that uses a layer of still seawater over a horizontally oriented module. “Full or…
The selected projects will be eligible for EU funding from the Connecting Europe Facility and will benefit from streamlined approval and regulatory processes. December 5, 2025 Sergio Matalucci The European Commission has given 235 cross-border energy projects the status of Projects of Common Interest (PCIs) and Projects of Mutual Interest (PMIs), the second list of such projects since its launch in 2023. Among the 235 projects, 100 will be hydrogen and electrolyser projects. The selected projects will be eligible for EU funding from the Connecting Europe Facility and will benefit from streamlined approval and regulatory processes. “The Commission will support…
Grids are becoming smart around the world, although some countries are investing more than others in modernizing their electricity grids. According to online data portal statistically, cumulative investments in electricity grids This is expected to increase across all regions between 2024 and 2050, with the largest amount coming from the Asia-Pacific region. But as this happens, cyber attacks on the power grid are also increasing. A report from Tech Monitor indicates that the average number of weekly cyber attacks on utilities, measured in 2024, has quadrupled since 2020. Most of these do not cause widespread damage or disconnections to the…
