Researchers from Zhejiang University have identified critical parameters governing crystallization in sheet-coated perovskite films, clarifying routes for producing high-efficiency solar cells and optoelectronics on a commercial scale. The review focuses on barriers caused by uneven crystallization, defects and instability that arise when perovskite deposition exceeds laboratory dimensions. Blade coating combines simplicity with continuous production capabilities and efficient use of materials, making it a leader in the field of mass production. However, the method introduces variability in film thickness, crystallinity and defect concentration. The complex nucleation and growth dynamics during coating cause inconsistencies that reduce device efficiency and compromise long-term stability.…
An installer completes a GoodLeap project. The Home Investment Tax Credit (ITC) has helped millions of Americans switch to solar energy over the years by making installations more affordable. More than 1.2 million homeowners claimed the 30% tax credit in tax year 2023, but that number will soon drop to zero with the residential ITC ending on December 31, 2025. While the One Big Beautiful Bill Act (HR1) eliminated the 25D direct solar incentive for homeowners, it retained another tax credit for the residential solar industry. Third-party (TPO) companies successfully lobbied Congress to preserve the 48E ITC, giving them until…
Chinese manufacturer Phono has launched a new bifacial solar panel to the Australian market with a power of 475 W and an energy conversion efficiency of 23.27%. November 19, 2025 Emiliano Bellini By pv magazine USA Chinese module manufacturer Phono has unveiled the Quasar 475 W solar panel, based on back-contact n-type technology. The China-based PV company said the double-glazed dual-sided solar module delivers 475W, with a peak efficiency of 23.27%. The product, identified as PS475L7GFH-18/VBH | 475W | N – BC, measures 1,800 mm x 1,134 mm x 30 mm and weighs 23.5 kg. They are built with 2.0mm…
The government will include thermal batteries in its expanded Boiler Upgrade Scheme, in a bid to accelerate the pace of clean energy deployment in homes. In an announcement from the Department for Energy Security and Net Zero (DESNZ), Energy Consumers Minister Martin McCluskey said the Government will offer a £2,500 discount on the cost of heating batteries, alongside advice on the role that innovative clean heating solutions can play, including thermal storage, infrared panels and renewable fuels. Heat batteries store thermal energy from sources such as solar energy, wind energy or heat pumps and can remove that heat on demand.…
The IF25 Heat Auction will provide a fixed premium subsidy to projects that electrify industrial processes using technologies such as heat pumps, induction heating, solar thermal energy and geothermal heating systems. The bidding window is expected to open in early December. November 19, 2025 Patrick Jowett The European Commission is organizing a €1 billion pilot auction across Europe to support industrial heat decarbonisation. The IF25 heat auction, made available under the EU Innovation Fund, will focus on heat used in manufacturing sectors such as chemicals, steel and cement, supporting electrified and directly renewable heat technologies. The bidding window will open…
Downing Renewable Developments will build a 40MW solar PV project to power an AI data center in Essex. The company has signed a long-term power purchase agreement (PPA) with Kao Data, a data center developer and operator, to power an “award-winning” data center campus in Harlow, Essex. Downing said it expects the Green Data Solar Farm project to be “one of the first” ground-mounted PV systems in Britain to directly power a colocation data centre. Kao Data said the Harlow campus is Britain’s “largest” currently under development, and the PPA agreement will support its target of becoming completely net zero…
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…
