(A) Without substrate, the perovskite forming at 100°C contracts vertically and laterally during cooling. (B) With the substrate adhesion, the annealed perovskite film only contracts vertically. (C and D) In situ out-of-plane XRD of scraped powder (C) and annealed film (D) at different temperatures.
