Low‐toxic bismuth‐based perovskites are prepared for the possible replacement of lead perovskite in solar cells. The perovskites have a hexagonal crystalline phase and light absorption in the visible region. A power conversion efficiency of over 1% is obtained for a solar cell with Cs 3 Bi 2 I 9 perovskite, and it is concluded that bismuth perovskites have very promising properties for further development in solar cells.
