In article number 2100101, Maning Liu, Paola Vivo, and co‐workers report that manganese (Mn) doping of bismuth‐based perovskite nanocrystals (Cs 3 Bi 2 I 9 ) promotes their synthesis to obtain a high phase purity of the host nanocrystals. The valence band of the host nanocrystals is deepened by the increase of Mn‐doping concentration, resulting in an enhanced open‐circuit voltage and a prolonged electron lifetime in solar cell applications.
