Abstract Hole‐selective self‐assembled monolayers (SAMs) have emerged as a novel recombination junction material critical in the development of high‐performance photovoltaic devices. However, SAMs tend to accumulate on substrates and can be desorbed by strong polar solvents, resulting poor‐quality perovskite films. Herein, simple phosphonic acid SAM molecule named V3PACz with vinyl ether side groups is first strategically developed for situ fabrication polymeric hole‐transport layer (HTL). The chain improves surface polarity solubility SAM. More importantly, enable polymerization, forming densely packed stable HTL high conductivity anti‐solvent resistance. Meanwhile, Poly‐V3PACz synchronously provides satisfied wettability interfacial functionalization. Utilizing these advantages, Poly‐V3PACz‐based device achieves champion power conversion efficiency 25.21%, which represents one highest reported efficiencies crosslinked HTLs inverted PSCs. unencapsulated maintained 92.1% its initial PCE after 500 h storage at 85 °C (dark), 91.9% 1200 tracking maximum point (MPP).

Abstract While the 2D/3D heterojunction is an effective method to improve power conversion efficiency (PCE) of perovskite solar cells (PSCs), carriers are often confined in quantum wells (QWs) due unique structure 2D perovskite, which makes charge transport along out‐of‐plane direction difficult. Here, a ferroelectric formed by 4,4‐difluoropiperidine hydrochloride (2FPD) inverted PSCs reported. The enriched 2 PbI 4 layer with n = 1 on surface exhibits response and has oriented dipoles direction. ferroelectricity dipole facilitates enhancement built‐in electric field (1.06 V) delay cooling process hot carriers, reflected high carrier temperature (above 1400 K) prolonged photobleach recovery time (139.85 fs, measured at bandgap), improving conductivity. In addition, alignment energy levels optimized exciton binding (32.8 meV) reduced changing dielectric environment surface. Finally, 2FPD‐treated achieve PCE 24.82% (certified: 24.38%) synergistic effect defect passivation, while maintaining over 90% their initial after 1000 h maximum point tracking.

Abstract Microscale imperfections and inhomogeneity at buried interface leads to energy losses insufficient carrier extraction of wide bandgap (WBG) perovskite solar cells (PSCs). Here, we report a collaborative strategy by introducing 3‐aminopropanoic acid (3‐APA) mix with [4‐(3,6‐dimethyl‐9H‐carbazol‐9‐yl)butyl]phosphonic (Me‐4PACz) as hole‐selective self‐assembled monolayer (SAM). With the addition 3‐APA, wettability precursors is increased. Furthermore, film morphology heterogeneity improved. As result, nonradiative recombination interfacial loss are greatly suppressed. This also marginally higher ionization potential monolayers, approximating valence band film. Benefits from suppressed charge transfer loss, mixed SAM present overcome passivation transport trade‐off, delivering V OC × FF 84.5% S–Q limit. The combine benefits enable efficient 1.67 eV WBG PSCs power conversion efficiency 22.4% high open circuit voltage 1.255 fill factor 85.5%. Under strategy, demonstrat all‐perovskite tandem 28.4%.
