Abstract Uncontrolled deposition of tin oxide (SnO 2 ) colloidal nanoparticles and perovskite precursors poses challenges for improving the efficiency stability solar cells (PSCs). Modifying electron transport layer (ETL) can both enhance its own performance influence crystallization kinetics upper layer. This study incorporates chain‐like surfactants with spatially opposite charges ETL modification. It is found that molecular conformational changes induced by flexibility carbon chain lead to collapse urchin‐like structure, impacting passivation effect SnO deposition. Due more stable conformation short‐chain surfactant, fully extended chains in micelles form a establishing stronger aggregation barrier ensures uniform The ordered distribution molecules allows functional groups be exposed on surface facilitates interlayer approach enhances across layers, alleviates interfacial tensile stress, promotes contact, extends processing window perovskite, thereby ensuring high‐performance PSCs. Ultimately, an optimized substrate strategy increases PSC device from 22.21% 24.12%, greatly improves unencapsulated under various conditions, providing new option modification engineering.

Interface engineering has significantly boosted perovskite solar cell efficiency and stability. However, numerous approaches focus on addressing defects at the interfaces between transport layers while neglecting potential issues within bulk material. Here, a multifunctional molecule, sodium lignosulfonate (SL), containing three types of functional groups, was introduced as chemical bridge perovskite/SnO2 interface. The SL bridges promote energy level alignment interface regulate crystallization process. Meanwhile, coordinated interactions components with −OH −SO3– groups SL, coupled Na+ diffusion, effectively passivate buried bulk. As result, champion SnO2–SL based n-i-p PSC achieved power conversion efficiencies 25.73% 25.13% rigid flexible substrates, respectively. Unencapsulated devices maintained 92.9% their initial after 2,550 h maximum point-tracking under 1-sun illumination in an inert atmosphere.

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.
