As a typical light-absorber, the three-dimensional (3D) metal halide perovskite materials exhibit superior optoelectronic properties (i.e., the low binding energy, long carrier lifetime and diffusion length, and high defect tolerance). The 3D perovskite-based perovskite solar cells (PSCs) show the excellent photoelectric conversion efficiency. However, its sensitivity to light, heat, and humidity as well as other environment factors restrict its practical application. Compared with three-dimensional perovskite, two-dimensional (2D) perovskites with high exciton binding energy and stable chemical properties enhance the long-term stability of devices. Combined with 2D perovskite, 3D/2D multi-dimensional perovskite cells can deliver a superior stability without a sacrificing efficiency. This review summarized the crystal structure and stability of 2D perovskite, and highlighted the research advances about the preparation technology and stability of 3D/2D multi-dimensional perovskite materials and relative photovoltaic devices. In addition, the further improvement of efficiency and stability of 3D/2D multidimensional PSCs was also prospected, thus providing a guidance for the commercialization of perovskite photovoltaic.
