Perovskite solar cells (PSCs) have emerged as a leading low‐cost photovoltaic technology, achieving power conversion efficiencies (PCEs) of up to 26.1%. However, their commercialization is hindered by stability issues and the need for controlled processing environments. Carbon‐electrode‐based PSCs (C‐PSCs) offer enhanced cost‐effectiveness compared traditional metal‐electrode PSCs, i.e., Au Ag. challenges persist, particularly in air conditions where moisture sensitivity poses significant hurdle. Herein, novel technique presented planar C‐PSCs that incorporates antisolvent vapors, such chlorobenzene, into air‐quenching process. This method effectively mitigates moisture‐induced instability, resulting champion PCEs exceeding 20% robust under ambient conditions. The approach retains 80% initial efficiency after 30 h operation at maximum point without encapsulation. antisolvent‐mediated represents advancement scalable production C‐PSCs, paving way future large‐scale deployment.

Abstract In recent years, carbon‐based printable mesoscopic perovskite solar cells (p‐MPSCs) without hole transport layers have garnered considerable interest because of their outstanding benefits in terms stability and cost. However, the use carbon electrodes instead materials noble metal leads to energy level mismatch, which limits power conversion efficiency (PCE) p‐MPSCs. this work, a molecular doping strategy is proposed employing cyclopentylmethanamine passivate surface subsurface crystal defects while inducing an shift toward p‐type region within electrodes. This approach facilitates formation homojunction at micro‐interfaces between perovskites. Results demonstrate that optimizes internal alignment devices, thereby increasing driving force for transfer Ultimately, devices optimized through increase PCE from 17.50% 19.50% retaining over 92% initial after 150 days air ambiance. study provides straightforward effective designing high‐efficiency stable

Abstract The dipole moment of hole transport materials (HTMs) plays a vital role in improving the photovoltaic performance inverted perovskite solar cells (PSCs). However, manipulating moments polymer HTMs, which have great operational and bias stability, remains challenging. In this work, HTMs with varying lengths glycol side chains, PTAC‐DEG PTAC‐TEG, are developed. Using random‐walk model extended from chain conformation, (with shorter chains) achieves higher cumulative than PTAC‐TEG. This finding can be attributed to fact that smaller angles enable better alignment, while larger PTAC‐TEG promote aggregation reduces integrated moment. Perovskite films on show enhanced crystallinity lower trap density due improved interfacial charge transport, stronger built‐in electric field, affinity dipole. devices achieve PCE 25.8%, is among highest for PSCs based exhibit outstanding stability under ISOS‐L‐3 (t 95 = 1300 h) ISOS‐D‐3 1200 conditions. study highlights modulation as promising strategy designing efficient, stable cells.
