Wide-bandgap (WBG) perovskites play a crucial role in perovskite-based tandem cells. Despite recent advances using self-assembled monolayers (SAMs) to facilitate efficiency breakthroughs, achieving precise control over the deposition of such ultrathin layers remains significant challenge for large-scale fabrication WBG perovskite and, consequently, modules. To address these challenges, we propose facile method that integrates MeO-2PACz and Me-4PACz optimal proportions (Mixed SAMs) into precursor solution, enabling simultaneous codeposition SAMs. This technique promotes spontaneous formation charge-selective contacts while reducing defect densities by coordinating phosphonic acid groups with unbonded Pb2+ ions at bottom interface. The resulting solar cells (PSCs) demonstrated power conversion 19.31% small-area devices (0.0585 cm2) 17.63% large-area modules (19.34 cm2), highlighting potential this strategy fabricating high-performance, PSCs enhanced reproducibility.

Lately, carbazole-based self-assembled monolayers (SAMs) are widely employed as effective hole-selective layers (HSLs) in inverted perovskite solar cells (PSCs). Nevertheless, these SAMs tend to aggregate solvents due their amphiphilic nature, hindering the formation of a monolayer on ITO substrate and impeding passivation deep defects perovskites. In this study, series new including DPA-B-PY, CBZ-B-PY, POZ-B-PY, POZ-PY, POZ-T-PY, POZ-BT-PY synthesized, which interfacial repairers coated atop CNph SAM form robust SAM@pseudo-planar HSL efficient PSCs. The strategy enables well-aligned interface with perovskites, synergistically promoting crystal growth, improving charge extraction/transport, minimizing nonradiative recombination loss. As result, POZ-BT-PY-modified PSC realizes an impressively enhanced efficiency up 24.45% together fill factor 82.63%. Furthermore, wide bandgap achieving over 19% efficiency. Upon treatment monolayer, also demonstrates non-fullerene organic photovoltaics (OPVs) based PM6:BTP-eC9 blend, achieves 17.07%.
