With the development of emerging photovoltaic cells, halide perovskite materials have been paid much attention. Among them, all-inorganic perovskites hold a great promise in the fields of optoelectronic and photovoltaic devices because of their good thermal stability, high absorption coefficient, adjustable band gap, and simple preparation process. The highest photoelectric conversion efficiency of all-inorganic perovskite solar cells has reached 20.4%. In this paper, the photoelectric conversion efficiency and stability of the solar cells were summarized based on all-inorganic perovskite materials such as ABX3, A2BX6, A2B1+B3+X6 and perovskite-type. The key factors that affect the efficiency and stability, and the optimization methods were mainly analyzed. At last, challenges of the all-inorganic perovskite solar cell materials in the future were prospected.
