Abstract

Abstract: Due to the superior optoelectronic properties of halide perovskites, it has attracted wide attentions during the past decade, especially in the field of energy. When the dimension of halide perovskites reduces, novel properties will appear, such as large exciton binding energy, high photoluminescence quantum yield, and enlarged band gap. This way, low dimensional halide perovskites, especially two-dimensional (2D) halide perovskites, have attracted intensive attention in recent years and showed promising applications, including photodetectors, light emitting diodes (LEDs), and solar cells. Various methods were then developed for the synthesis of 2D halide perovskites and studying the exciting optoelectronic properties. The optoelectronic devices based on 2D halide perovskites showed excellent performance, particularly high sensitive photodetection, high electroluminescence with sharp emission peak, and environmental stable solar cells with decent power conversion efficiency. In this case, 2D halide perovskites become superstar materials in perovskites research area. In this review, we summarize the recent progresses in the synthesis and energy applications of 2D halide perovskites, and challenges and future directions in the field. Highlights: Different synthesis methods of 2D perovskites are summarized. Various unique optoelectronic properties of 2D perovskites are presented. Recent progress of 2D perovskites in energy related applications is thoroughly discussed. Challenges and future developments of 2D perovskites are as well highlighted.
