A room‐temperature perovskite material yielding a power conversion efficiency of 18.1% (stabilized at 17.7%) is demonstrated by judicious selection of cations. Both cesium and methylammonium are necessary for room‐temperature formamidinium‐based perovskite to obtain the photoactive crystalline perovskite phase and high‐quality crystals. This room‐temperature‐made perovskite material shows great potential for low‐cost, large‐scale manufacturing such as roll‐to‐roll processing.
