Abstract
Perovskite solar cells (PSCs) face the challenge of degradation due to the vulnerability of perovskites to environmental factors. Two-dimensional (2D) perovskite materials allow the enhancement of absorber robustness or provide protection for vulnerable 3D counterparts, leading to improved stability of PSCs. However, the improved stability comes at the expense of efficiency; additional engineering strategies are needed to achieve simultaneously high efficiency and stability. Herein, we summarize the crystal structure and characteristics of different 2D perovskite materials and the performance of the PSCs with each type. In addition, the contributions of 2D perovskites to the improvement of device stability and efficiency are systematically analyzed from the point of view of compositional, dimensional, interfacial, and tandem cell engineering.
