Abstract Perovskite solar cells (PSCs) are of significant interest for researchers as the next‐generation energy harvesters. However, PSCs suffer from traps that densely distributed at interfaces, which deteriorate device's performance. To address this issue, a new small molecule (DTAQTPPO) capable trap passivation on perovskite layer surface while possessing ambipolar charge extraction properties is designed, endow DTAQTPPO with dual functionality both interface defect passivator and efficient hole/electron extractor in n‐i‐p p‐i‐n architectures. These beneficial effects improve power conversion efficiencies (PCEs) to 23.03% 23.55% under 1 sun 37.18% 36.29% 1000 lux light‐emitting diode (LED) indoor illuminations architectures, respectively, after incorporating DTAQTPPO. In addition, enhance PV using an anti‐solvent‐free PCE 23.24% 35.47% LED illumination, respectively. results suggest can be widely used multifunctional interlayer versatile device architectures various light illumination conditions generality different perovskites processes.
