A New Recipe Could Make Better Solar Cells begins with a clear news idea: Our next story is about a recipe, but not the kind you eat. Scientists are working on materials called perovskites. Perovskites are crystals that can be used in solar cells, which turn sunlight into electricity, and in LEDs, which make light. One challenge is that the crystals need to grow neatly. If the crystal structure is messy, the solar cell may not work as well or last as long. Researchers tested a method that uses a temporary melting liquid to help the perovskite crystals form in a more
