New Light on an Old Story: Perovskites Go Solar

All in one: Perovskites are currently undergoing a renaissance as “allrounder” materials for solar cells. For a special type of methylammonium lead halide perovskites, a unique combination of properties, including high charge‐carrier mobilities, exciton lifetimes, and panchromatic absorption, was observed, which renders this class of hybrid perovskites one of the most promising absorber and ambipolar charge‐transport materials for all‐solid‐state solar cells.
