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.

Abstract The complete phase transition from DMAPbI 3 and Cs 4 PbI 6 intermediates to the final CsPbI perovskite is pivotal for fabricating high‐quality inorganic films. In this study, reaction energy barrier between sought be reduced by increasing their surface energy, where a perfluorinated compound designed using DFT modeling saturate of effectively prevent crystalline growth. Consequently, smaller with ultrahigh react more energetically facilitate rapid conversion desired phase. It found that resultant shows improved crystallinity morphology, as demonstrated suppressed non‐radiative recombination prolonged carrier lifetimes. As result, optimized solar cells (PSCs) achieve power efficiency (PCE) over 20%, along significantly light thermal stability. This work provides way regulate crystallization dynamics advanced quality perovskites.
