Organic solar cells have long promised a future of lightweight, flexible energy harvesting, but their tendency to degrade under sustained light and heat has kept them from competing with silicon ...

Solar power continues to grow—accounting for most new capacity added to U.S. electric grids in 2024—but the mid-1950s technology most often used to capture the sun's energy comes with environmental ...

A domestic research team has developed a high-efficiency perovskite solar cell with a lifespan more than tripled. They succeeded by developing a material that can replace an additive that boosts ...
