Abstract Inverted perovskite solar cells (PSCs) have attracted considerable attention due to their distinct advantages, including minimal hysteresis, cost‐effectiveness, and suitability for tandem applications. Nevertheless, the solution processing low formation energy of perovskites inevitably lead numerous defects formed at both bulk interfaces layer. These can act as non‐radiative recombination centers, significantly impeding carrier transport posing a substantial obstacle stability further enhancing power conversion efficiency (PCE). This review delves into detailed discussion nature origin characterization techniques employed defect identification. Furthermore, it systematically summarizes methods detection approaches passivating interface within film in inverted PSCs. Finally, this offers perspective on employing upscaling passivation engineering modules. It is hoped provides insights PSCs

Surface passivation has driven the rapid increase in power conversion efficiency (PCE) of perovskite solar cells (PSCs). However, state-of-the-art surface techniques rely on ammonium ligands that suffer deprotonation under light and thermal stress. We developed a library amidinium ligands, interest for their resonance effect–enhanced N–H bonds may resist deprotonation, to stability layers surfaces. This strategy resulted >10-fold reduction ligand equilibrium constant twofold maintenance photoluminescence quantum yield after aging at 85°C illumination air.
