Designers of solar cells may soon be setting their sights higher as a discovery by a team of researchers has revealed a class of materials that could be better at converting sunlight into energy than those currently being used in solar arrays. Their research shows how a material can be used to extract power from a small portion of the sunlight spectrum with a conversion efficiency that is above its theoretical maximum -- a value called the Shockley-Queisser limit.
This finding could lead to more power-efficient solar cells.Image credit: Drexel University/Ella Marushcenko
