Recent progress in inverted perovskite solar cells (IPSCs) mainly focused on NiOx modification and (PVK) regulation to enhance efficiency stability. However, most works address only monofunctional modifications, identical molecules with the ability simultaneously optimize interface bulk phase have been rarely reported. This work proposes a dual approach using 4-amino-3,5-dichlorobenzotrifluoride (DCTM) both upper interfaces reduction of defects perovskite. Amino group DCTM increases Ni3+/Ni2+ ratio NiOx, thereby increasing conductivity optimizing energy alignment. Additionally, fills Pb2+ I– vacancies perovskite, which improves vertical orientation grains subsequently reduces nonradiative recombination, achieving increased carrier lifetime. PVK modified by exhibits enhanced level alignment electron transport layer, while femtosecond transient absorption (TA) spectroscopy confirms that facilitates efficient transport, leading high-performance IPSCs. The optimized IPSCs achieve maximum 22.8% reduced hysteresis (0.7%). Moreover, unencapsulated device preserves over 80% its initial power conversion (PCE) after 1000 h stored air at 30% relative humidity. strategy monomolecular offers straightforward solution for optimization provides new insights into selecting aniline-derived

However, the incomplete coverage of SAMs and non‐intimate interface contact between perovskite/SAMs usually cause inferior characteristics significant energy losses at heterojunction interface.

Simultaneously, fill voids form dense hybrid SAMs, resulting uniform surface potential improved contact. Moreover, treatment also tends induce oriented crystallization films, passivate defects, release lattice stress Consequently, CB‐PA‐based PSCs achieve champion efficiency 25.27% superior operational stability, retaining ≈94% their initial after maximum power point (MPP) tracking (65 °C) for 1000 h ISOS‐L‐2I protocol.
