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.
