Abstract

Metal-halide perovskites have attracted much attention as light absorbers in light harvesting applications. The primary advantages of these perovskites for light harvesting are the large photon absorption coefficient, long-range balanced charge carrier diffusion lengths, low trap density, high charge carrier mobility, fast and efficient photo-generated exciton dissociation and slow electron-hole bimolecular recombination. Additional to these properties, the completely tunable optical direct bandgap over a wide range also makes these perovskites good candidates for using in light emission. Herein, we briefly review the development, state-of-the-art and the prospective outlook of this new light emission medium.
