Brussels, Belgium (SPX) Dec 09, 2025 Researchers at the Vrije Universiteit Brussel and partners have mapped how emerging chalcogenide semiconductor absorbers behave in photoelectrochemical systems that convert sunlight and CO2 into chemical fuels. They examined how the electronic band structure of these materials governs charge generation, separation, and transfer at the semiconductor - electrolyte interface, and how these processe

Berlin, Germany (SPX) Dec 14, 2025 Researchers in Munich and international partners have raised the efficiency of perovskite-silicon tandem solar cells to 31.4 percent by tailoring the molecular contacts at the interface between the absorber and charge collection layers. The team reports the result in the journal Joule and notes that the tandem cell was manufactured entirely in the Munich region on crystalline silicon bottom cell

Tokyo, Japan (SPX) Dec 14, 2025 Researchers from Beijing Normal University and Qingdao University have developed a nonfused ring electron acceptor (NFREA) called TT-Ph-C6 that improves the performance of thick-film organic solar cells. The material targets limitations in film-thickness tolerance and fill factor that have held back NFREAs compared with fused-ring acceptors. The team, led by Prof. Zhishan Bo, Prof. Cuihong

Los Angeles CA (SPX) Dec 11, 2025 Overview Energy has revealed an airborne power-beaming demonstration that transmitted energy from a moving aircraft to a ground receiver 5 kilometers below, marking its second major step toward delivering grid-scale solar power from space. The test used the same optics and laser chain planned for space operations and showed that the system can send power via near-infrared light from an air

Berlin, Germany (SPX) Dec 11, 2025 Perovskite solar cells can be made more robust, efficient, scalable and cheaper to manufacture by replacing indium tin oxide with single-walled carbon nanotubes in the device architecture, according to research led by the University of Surrey. The team reports that substituting indium tin oxide, a fragile and costly photovoltaic material, with single-walled carbon nanotubes could support flexibl

Tokyo, Japan (SPX) Dec 05, 2025 A research team at Wuhan University of Technology led by Professor Tao Wang has developed a vacuum-assisted thermal annealing (VTA) process that tackles the linked challenges of efficiency and stability in organic solar cells. The method engineers the internal structure of the photovoltaic active layer so that devices maintain strong performance over long operating times. The work focuses

Berlin, Germany (SPX) Dec 04, 2025 Perovskite solar cells are under development as candidates for next generation photovoltaic modules, but commercial use remains limited by long term instability driven in part by migrating ions in the absorber layer. A team from Helmholtz-Zentrum Berlin (HZB) and the University of Potsdam has now measured ion densities in four widely used perovskite compounds and found substantial differences be

Tokyo, Japan (SPX) Dec 03, 2025 A study published in Science Bulletin describes a solar-driven system that produces freshwater while capturing boron from seawater and brine using a composite gel identified as (MXene-MgO)@sodium alginate (MMS). The work targets the interlinked pressures on water, food, and energy supplies in regions such as Yemen, Pakistan, and Haiti, where demand is rising and water scarcity and hunger are sev

Tokyo, Japan (SPX) Nov 26, 2025 Researchers from the Korea Institute of Energy Research and Chungbuk National University have pinpointed two distinct types of defects responsible for power loss in silicon heterojunction solar cells. The team, led by Dr. Hee-Eun Song of KIER and Professor Ka-Hyun Kim of CBNU, identified slow and fast component defects using a refined method of Deep Level Transient Spectroscopy that captures the

Tokyo, Japan (SPX) Nov 18, 2025 Researchers at Zhejiang University have mapped critical parameters governing crystallization in blade-coated perovskite films, clarifying pathways to manufacture high-efficiency solar cells and optoelectronics at commercial scale. The review addresses barriers posed by uneven crystallization, defects, and instability that emerge when perovskite deposition scales beyond laboratory dimensions.

Corvallis OR (SPX) Nov 18, 2025 Floating solar panels are emerging as a promising clean energy solution with environmental benefits, but a new study finds those effects vary significantly depending on where the systems are deployed. Researchers from Oregon State University and the U.S. Geological Survey modeled the impact of floating solar photovoltaic systems on 11 reservoirs across six states. Their simulations showed

Berlin, Germany (SPX) Nov 15, 2025 The Instrumentation and Industrial Electronics research group at the University of Cordoba has implemented a sensor-based system for monitoring solar power plants.
