Abstract: A multiple cation-doped perovskite compound includes a perovskite represented by a formula of ABX3. A includes M1, M2, and M3. M1 represents a cation different from M2 and M3; M2 represents a cesium ion and M3 represents a formamidinium ion. B represents a divalent cation different from M1, M2, and M3. X includes at least two different halide ions. In addition, the perovskite compound is free from methylamine ion. A perovskite solar cell including the multiple cation-doped perovskite compound is also provided.
