In article number 1908343, Yumin Liu, Xing‐Zhong Zhao, and co‐workers develop a δ‐CsPbI 3 intermediate phase growth (IPG) strategy for achieving high and controllable Cs + incorporation and fabricating large‐grain perovskite thin films. The δ‐CsPbI 3 phase in the PbI 2 film, which serves as the cesium source, facilitates the growth of perovskite grains. This CsPbI 3 ‐IPG is a facile and effective strategy to produce large‐grain Cs + incorporated perovskite films via sequential deposition.
