Abstract [4‐(3,6‐dimethyl‐9H‐carbazol‐9yl)butyl]phosphonic acid (Me‐4PACz) self‐assembly material has been recognized as a highly effective approach for mitigating nickel oxide (NiO x ) surface‐related challenges in inverted perovskite solar cells (IPSCs). However, its uneven film generation and failure to effectively passivate the buried interface defects limit device‘s performance improvement potential. Herein, p‐xylylenediphosphonic (p‐XPA) containing bilateral phosphate groups (−PO 3 H 2 is introduced an layer between NiO /Me‐4PACz layer. P‐XPA can flatten surface of hole transport optimize contact. Meanwhile, p‐XPA achieves better energy level alignment promotes interfacial transport. In addition, −PO chelate with Pb 2+ form hydrogen bond FA + (formamidinium cation), thereby suppressing non‐radiative recombination loss. Consequently, IPSC modification champion power conversion efficiency 25.87 % (certified at 25.45 %) laboratory scale (0.0448 cm ). The encapsulated target device exhibits operational stability. Even after 1100 hours maximum point tracking 50 °C, remains impressive 82.7 initial efficiency. Molecules featuring passivation contact inhibit recombination, providing enhancing stability devices.

Abstract The utilization of Ag electrodes in inverted perovskite solar cells (PSCs) is prevalent; however, their inherent reactivity and corrosive characteristics toward materials often lead to significant stability concerns. Here, 1‐ethyl‐3‐methyl‐1h‐imidazolium 2‐mercaptobenzothiazole (EM) ionic liquid designed introduce it into the bathocuproine (BCP) barrier layer mitigate potential chemical corrosion electrode by layer. EM forms multiple interaction modes through coordination two types bonds, C─N, C═N, C─S, chelation with Ag, resulting formation a dense anti‐corrosion on surface. By raising electrode's decreasing its current, occurrence reactions effectively suppressed. Additionally, ionized optimizes band structure conductivity BCP enhances electron transfer capability at transport layer/Ag interface. BCP:EM‐based PSCs exhibit an efficiency 25.11% excellent stability. Under continuous operation 45 °C one sun illumination, encapsulated device maintains 85.6% initial after 1000 h maximum power point.
