| Abstract | In recent years, perovskite solar cells (PSCs) have gone through unparalleled rapid expansion and become a candidate for solar cells. Among various PSCs, though typical three-dimensional (3D) halide perovskite-based PSCs deliver the highest efficiency, they are subjected to severe instability, which constrains their commercializability. In comparison, two-dimensional (2D) PSCs have aroused widespread concern due to their superior stability. After that, 2D/3D perovskite materials combining high efficiency and good stability have emerged as the times require, which are expected to bring about stable and efficient PSCs. Here, this review focuses on selection of functional spacer cations for efficient and stable 2D/3D PSCs. First, the unique function of different spacer groups and the selection of appropriate spacer cations in 2D perovskites is summarized and proposed. Then, by selecting appropriate cations, the role of 2D perovskites is elaborated, including energy level regulation, ion migration suppression, defect passivation, residual stress release and improved stability. In addition, the preparation methods of 2D/3D perovskites are comprehensively summarized. Finally, current challenges and future opportunities for the further development of 2D/ 3D perovskites for solar cells are discussed and prospected. |
