Abstract Self‐assembled monolayers (SAMs) as hole‐collecting materials have made remarkable progress in inverted perovskite solar cells (PSCs). However, the incomplete coverage of SAMs and non‐intimate interface contact between perovskite/SAMs usually cause inferior characteristics significant energy losses at heterojunction interface. Herein, a post‐assembled chelating molecular bridge strategy using 5‐(9H‐carbazol‐9‐yl)isophthalicacid (CB‐PA) is developed to modify buried It found that CB‐PA can be chemically coupled with MeO‐2PACz through π–π stacking carbazole groups, chelate by forming double C═O···Pb bonds, thus constructing bridge‐connected promote carrier extraction. 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. This work provides an innovative address challenges high‐performance PSCs.

Abstract The low crystallinity of the perovskite layers and many defects at grain boundaries within bulk phase interfaces are considered huge barriers to attainment high performance stability in solar cells (PSCs). Herein, a robust photoelectric imidazole‐linked porphyrin‐based covalent organic framework (PyPor‐COF) is introduced precisely control crystallization process effectively passivate through sequential deposition method. 1D porous channels, abundant active sites, orientation PyPor‐COF offer advantages for regulating PbI 2 eliminating defects. Moreover, intrinsic electronic characteristics endow more closely matched energy level arrangement layer, which promotes charge transport thereby suppresses recombination photogenerated carriers. champion PSCs containing achieved power conversion efficiencies 24.10% (0.09 cm ) 20.81% (1.0 ), respectively. unpackaged optimized device able maintain its initial efficiency 80.39% even after being exposed air 2000 h. also exhibits excellent heating light stability. This work gives new impetus development highly efficient stable via employing COFs.

Abstract The two‐step method for perovskite solar cells (PSCs) offers a promising technology scalable manufacturing, particularly under ambient air conditions, due to its inherent simplicity, high reproducibility, and operational convenience. With this approach, achieving high‐quality of lead iodide (PbI 2 ) films during the initial stage is paramount ensuring overall performance stability devices. However, fabrication PbI , residual boiling point hygroscopic dimethyl sulfoxide (DMSO) solvent significantly compromises resulting film quality. Here, L‐Homoarginine hydrochloride (HargCl) introduced into precursor solution, which greatly reduced amount ·xDMSO passivated internal defects (PVK) films. By leveraging strategy, inverted entirely in are successfully prepared, an impressive power conversion efficiency (PCE) 25.05% — highest reported date fully air‐processed PSCs. In addition, these unencapsulated devices maintained 96% their after 500 h storage with 20–40% RH.

Abstract Interfacial localized charges and interfacial losses from incompatible underlayers are critical factors limiting the efficiency improvement market‐integration of perovskite solar cells (PSCs). Herein, a novel chemical tuning strategy is proposed involving proton transfer between amine head pyridoxamine (PM) phosphonic acid anchoring group [4‐(3,6‐dimethyl‐9H‐carbazol‐9‐yl)butyl]phosphonic (Me‐4PACz), with simultaneous enhancement charge delocalization through electrostatic attraction opposite charged molecules. The Me‐4PACz‐PM polarization interface modulates nickel oxide (NiO x ) states coordination environment at buried interfaces, consequently enhancing p‐type conductivity obtaining more compatible band arrangement. high‐coverage wettability NiO /Me‐4PACz‐PM underlayer also facilitate deposition high‐quality films, releasing lattice strain mitigating trap‐assisted non‐radiative recombination. Attributing to implementation tunable small‐area devices modules an aperture area 69 cm 2 achieved impressive power conversion efficiencies (PCEs) 26.34% (certified 25.48%) 21.94% 20.50%), respectively, unencapsulated maintained their initial PCEs ≈90% after aging for 2000 h (ISOS‐L‐1) 1500 (ISOS‐D‐1). broad applicability interfaces successful scaling large‐area provide reference expanding PSCs applications.
