The premature reaction of PbI 2 with organic cations in perovskite (PVK) precursor solutions often leads to compromised film quality. To mitigate this, the ionic liquid (IL) pyridinium trifluoromethanesulfonate is introduced into solution. strong interaction between and promotes formation nucleation clusters, effectively lowering barrier regulating crystallization perovskite, resulting high‐quality, homogeneous PVK films. In situ characterization shows that prenucleation strategy yields films an average grain size exceeding 1 μm. hydrophobicity trifluoromethyl group modulates humidity, facilitating moist environments. This contrast typical negative effects moisture, which can induce defects structures. As a result, IL‐modified solar cells (PSCs) achieved remarkable power conversion efficiency (PCE) 25.11% under ambient conditions. These PSCs retained 80.43% their initial PCE after 820 h continuous maximum point (MPP) tracking. Furthermore, 1000 exposure air 30%–50% relative humidity (RH) at room temperature, devices maintained 87% efficiency, demonstrating excellent stability for long‐term PSC applications.

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.
