Low‐dimensional perovskite materials and their optoelectronics

Abstract

Abstract Three‐dimensional (3D) organic–inorganic metal halide perovskite materials possess great potential applications for approaching efficient optoelectronics due to the unique optoelectronic properties of perovskite materials and cost‐effective manufacturing possibilities of optoelectronics. However, the scientific and technical challenges of 3D perovskite materials were their inferior long‐term stability, which hampered their practical applications. The low‐dimensional perovskite materials composed of alternating organic and inorganic layers are one of the most credible paths toward stable perovskite photovoltaics and optoelectronics. In this short review, we first present a discussion of the crystal structure and nontrivial optoelectronic properties of the low‐dimensional halide perovskites. The synthetic methods for the preparation of the low‐dimensional halide perovskites are reviewed. After that, we focus on the recent development of perovskite photovoltaics, light‐emitting diodes, and lasers by the low‐dimensional halide perovskites. Finally, we outline the challenges of the low‐dimensional halide perovskites and their applications.
