Abstract Further improvements in photocurrent are essential to unlock higher efficiencies inverted (p‐i‐n) perovskite solar cells (PSCs). While the use of textured substrates has proven successful normal structure (n‐i‐p) devices improve photocurrent, applying same approach p‐i‐n architecture is challenging due difficulties depositing ultra‐thin self‐assembled monolayers (SAMs) on uneven surfaces. To overcome this limitation, a rubidium‐based ammonia treatment for nickel oxide seed layers proposed. This strategy enhances surface homogeneity hole‐transporting substrates, facilitates defect passivation, and improves SAM anchoring, collectively enhancing hole extraction suppressing non‐radiative recombination. As result, optimized PSCs achieves champion power conversion efficiency (PCE) 25.66% with fill factor 86.35% demonstrates excellent long‐term stability, retaining 95% their initial PCE after 1,000 hours following ISOS‐L‐2I protocol. Moreover, scalability validated 1 cm 2 active area device, achieving 23.90%. These findings highlight potential address key challenges PSC interfaces advance commercial viability high‐performance photovoltaics.

Self-assembled monolayers (SAMs) have become pivotal in achieving high-performance perovskite solar cells (PSCs) and organic (OSCs) by significantly minimizing interfacial energy losses. In this study, we propose a co-adsorb (CA) strategy employing novel small molecule, 2-chloro-5-(trifluoromethyl)isonicotinic acid (PyCA-3F), introducing at the buried interface between 2PACz perovskite/organic layers. This approach effectively diminishes 2PACz's aggregation, enhancing surface smoothness increasing work function for modified SAM layer, thereby providing flattened with favorable heterointerface perovskite. The resultant improvements crystallinity, minimized trap states, augmented hole extraction transfer capabilities propelled power conversion efficiencies (PCEs) beyond 25% PSCs p-i-n structure (certified 24.68%). OSCs CA achieve remarkable PCEs of 19.51% based on PM1:PTQ10:m-BTP-PhC6 photoactive system. Notably, universal also been achieved other two popular OSC systems.

Self-assembled monolayer molecules have been widely employed as interfacial transport materials in inverted perovskite solar cells (PSCs), demonstrating high efficiency and improved device stability. However, self-assembling (SAM) often suffer from aggregation weak interactions with the layer, resulting inefficient charge transfer significant energy losses, ultimately limiting power conversion long-term stability of cells. In this work, we developed a series novel skeleton-matching carbazole isomer SAMs based on following key design principles: (1) introducing benzene ring structure to distort molecular skeleton SAM, thereby preventing achieving uniform distribution fluorine-doped tin oxide (FTO) substrates; (2) strategically incorporating methoxy groups onto at different positions (ortho, meta, para). These functional not only increase anchoring points layer but also fine-tune dipole moment. Among SAMs, m-PhPACz exhibits most favorable properties, maximum moment 2.4 D an O-O distance that aligns excellently diagonal lead ions adjacent lattice, enhancing SAM-perovskite interactions, facilitating efficient extraction, improving As result, new SAM-based PSCs achieved impressive 26.2%, 12.9% improvement. Moreover, devices demonstrated outstanding photothermal stability, retaining 96% their initial PCE after 1000 h 85 °C maintaining 90% 300 UV-light exposure.
