The efficiency and longevity of metal-halide perovskite solar cells are typically dictated by nonradiative defect-mediated charge recombination. In this work, we demonstrate a vapor-based amino-silane passivation that reduces photovoltage deficits to around 100 millivolts (>90% the thermodynamic limit) in bandgaps between 1.6 1.8 electron volts, which is crucial for tandem applications. A primary-, secondary-, or tertiary-amino-silane alone negatively barely affected crystallinity transport, but amino-silanes incorporate primary secondary amines yield up 60-fold increase photoluminescence quantum preserve long-range conduction. Amino-silane-treated devices retained 95% power conversion more than 1500 hours under full-spectrum sunlight at 85°C open-circuit conditions ambient air with relative humidity 50 60%.

Abstract Inverted NiO x ‐based perovskite solar cells (PSCs) exhibit considerable potential because of their low‐temperature processing and outstanding excellent stability, while is challenged by the carriers transfer at buried interface owing to inherent low carrier mobility abundant surface defects that directly deteriorates overall device fill factor. Present work demonstrates a chemical linker with capability simultaneously grasping crystals forming Ni−S−Pb bridge significantly boost transfer, based on rationally selected molecule 1,3‐dimethyl‐benzoimidazol‐2‐thione (NCS). The constructed not only reduces pinholes needle‐like residual PbI 2 interface, but also deepens function valence band maximum positions , resulting in smaller VBM offset between film. Consequently, modulated PSCs achieved high factor up 86.24 %, which as far we know highest value records inverted PSCs. NCS custom‐tailored minimodules (active area 18 cm ) exhibited champion efficiency 25.05 % 21.16 respectively. unencapsulated devices remains over 90 initial power point under continuous illumination for 1700 hours.
