10+ hour, 16+ min ago   (381+ words) “The scientific gap addressed in the present work is not the individual use of PVT, heat pumps, refrigerants, or TiO₂-based materials, but the experimentally resolved interaction between passive face thermal regulation, active refrigerant-based heat extraction, and seasonal refrigerant response within…...

2+ day, 10+ hour ago   (285+ words) The U.S. Department of Energy (DOE) Integrated Energy Systems Office (IESO) and Office of Critical Minerals and Energy Innovation are seeking innovative techniques to move space based solar power forward. The groups are launching a $12 million funding opportunity open to research…...

3+ day, 9+ hour ago   (371+ words) Researchers at China’s Nanjing University have fabricated a perovskite-organic tandem solar cell featuring a bottom organic subcell that uses a low-bandgap (LBG) acceptor to enhance near-infrared (NIR) absorption while reducing voltage losses. The researchers said previous studies have used various…...

3+ day, 12+ hour ago   (419+ words) Rocket Lab Corporation has announced the production release of its inverted metamorphic (IMM) Apex solar cell, a high-efficiency space power solution designed to eliminate reliance on germanium substrates and avoid critical-mineral supply chain bottlenecks. In an IMM structure, the semiconductor layers…...

4+ day, 9+ hour ago   (323+ words) The researchers built the monolithic perovskite-silicon tandem solar cell with a crystalline silicon (c-Si) bottom cell and an inverted p-i-n perovskite top cell. The silicon subcell features intrinsic amorphous silicon (a-Si(i)) and doped nanocrystalline silicon oxide (nc-SiOₓ(n)) passivating contacts,…...

4+ day, 11+ hour ago   (314+ words) WattPower has introduced its 506KTL grid-forming inverter, a 506 kW string inverter designed for utility-scale solar projects. The Indian manufacturer said the inverter is designed to help engineering, procurement and construction (EPC) companies and renewable energy developers meet evolving grid-code requirements while…...

4+ day, 12+ hour ago   (286+ words) Indian state-owned power utility NTPC has invited expressions of interest (EoI) for the development and installation of grid-connected battery energy storage systems (BESS) using sodium-ion battery technology at its existing thermal power plants and office buildings. The pilot program will…...

5+ day, 11+ hour ago   (458+ words) Pile load testing can therefore be particularly valuable for utility-scale PV projects. Static axial tension and pullout tests can establish actual load-displacement behavior, allowing geotechnical and structural engineers to optimize pile lengths rather than relying solely on conservative correlations. With…...

6+ day, 5+ hour ago   (282+ words) The initiative targets cadmium telluride (CdTe) and copper indium gallium selenide (CIGS) technologies, while the ability to process amorphous silicon (a-Si) modules would be considered an advantage. The deadline for submissions is Oct. 21, 2026. Only candidates that participate in the CEI…...

6+ day, 6+ hour ago   (391+ words) Chinese sodium-ion battery manufacturer HiNa Battery has signed a five-year agreement with South Korea’s Volta Co. for the supply of 10 GWh of sodium-ion batteries, marking a significant expansion of the companies’ existing cooperation. The strategic agreement was signed on Sept....
