Structure characterizations of perovskite films and schematic energy‐level diagrams in the PSCs. GIWAXS patterns of Sn perovskite films A,D) control, B,E) target‐pristine, C,F) target‐GuaSCN (2.5%) at an incidence angle of (A–C) 0.2° and (D–F) 1° respectively. Intensity plots of the GIWAXS patterns along the q z direction at an incidence angle of G) 0.2° and H) 1°. TOF‐SIMS depth profiles of the I) control, J) target‐pristine, and K) target‐GuaSCN (2.5%) film. Schematic crystal structures of the L) control, M) target‐pristine or target‐GuaSCN film, and their energy level diagrams with respect to the HTL and ETL.
