    Flipping a Chemical Switch helps Perovskite Solar Cells Beat the Heat

    April 26, 2016, Categories  Chemistry/Nanotechnology, Physics, Technology/Electronics

    Thin films of crystalline materials called perovskites provide a promising new way of making inexpensive and efficient solar cells. Now, an international team of researchers has shown a way of flipping a chemical switch that converts one type of perovskite into another -- a type that has better thermal stability and is a better light absorber.
