Abstract While the 2D/3D heterojunction is an effective method to improve power conversion efficiency (PCE) of perovskite solar cells (PSCs), carriers are often confined in quantum wells (QWs) due unique structure 2D perovskite, which makes charge transport along out‐of‐plane direction difficult. Here, a ferroelectric formed by 4,4‐difluoropiperidine hydrochloride (2FPD) inverted PSCs reported. The enriched 2 PbI 4 layer with n = 1 on surface exhibits response and has oriented dipoles direction. ferroelectricity dipole facilitates enhancement built‐in electric field (1.06 V) delay cooling process hot carriers, reflected high carrier temperature (above 1400 K) prolonged photobleach recovery time (139.85 fs, measured at bandgap), improving conductivity.

Besides, presence can optimize energy structure between PTAA, which facilitates charge transfer. Density functional theory (DFT) reveals that electron donor unit (R‐C ═ N) prefers bind with traps interface, while formation hydrogen bonds R‐NH I − strengthens above binding ability. Consequently, optimum API‐treated inverted formamidinium‐cesium (FA/Cs) PSCs yields a champion power conversion efficiency (PCE) 22.02% exhibited favorable stability.
