In article number 1901863, Fang‐Chung Chen and co‐workers use calculations of the Shockley‐Queisser limits under indoor light sources to reveal an unusual bandgap ( E g ) zone, in which the dependence of the power conversion efficiencies (PCEs) on the value of E g exhibits different trends from that under solar irradiation. Therefore, an increase in the Eg of perovskite materials improves the PCEs of perovskite solar cells under indoor lighting conditions.
