by Clarence Oxford Los Angeles CA (SPX) Apr 29, 2026 A new study describes a perovskite diode that achieves 26.7% power-conversion efficiency when operated as a solar cell and 31% external quantum efficiency when operated as a light-emitting diode, performance levels that would be considered strong for a device designed to do only one of […]

by Riko Seibo Tokyo, Japan (SPX) Apr 28, 2026 A new study published in the journal Biochar demonstrates that combining biochar with advanced polyzwitterionic hydrogels can sharply improve the performance of solar-driven water evaporation systems, offering a practical pathway toward low-energy desalination and water purification. Freshwater scarcity continues to intensify globally, with the […]

by Riko Seibo Tokyo, Japan (SPX) Apr 28, 2026 Researchers from Ocean University of China and Huzhou University have developed a phase-change photothermal foam that continues to produce freshwater after sunlight fades, addressing one of the core limitations of solar-driven desalination technology. The material, designated PPy-CS/PF@DDA, is constructed by confining dodecylamine inside a […]
