Quasi-2D perovskites represent an important catagory of perovskite materials, have attracted great attentions recently due to their outstanding optoelectrical properties. Quasi-2D perovskites feature with multi quantum-well structures, thus it is a strongly confined system comprising both quantum- and dielectric-confinement, which result in the formation of strongly bound excitons. Accordingly, efficient cascade energy transfer exist in their films state, that greatly affect the carrier recombination kinetics. In this talk, we will report our recent progresses in quasi-2D perovskite light-emitting diodes and photovoltaics. By carefully regulating the materials' crystallization and recombination kinetics, highly efficient quasi-2D perovskite optoelectronic devices have been achieved.
