Ultrathin perovskite nanocrystals suitable for use in tunable and energy-efficient LEDs

Perovskites have recently emerged as a most promising material for low-cost production of highly efficient solar cells. In particular, the so-called organic-inorganic metal halide perovskites are among the most exciting recent discoveries in the field of photovoltaics in. In less than five years, researchers have succeeded in increasing the energy-converting efficiency of perovskite-based solar cells from 4 to more than 20%. Indeed, in this respect, these relative newcomers have already overtake
