Tin halide perovskite (THP) has emerged as a promising lead-free material for high-performance solar cells, attracting significant attention their potential use energy conversion. However, the rapid crystallization of THP due to its high Lewis acidity and easy oxidation Sn2+ leads poor morphology rampant defects in resulting films. These strongly hamper advances efficiency stability cells. Herein, comprehensive regulation strategy is demonstrated by introducing methyl carbazate (C2H6N2O2, MeC) regulate kinetics through inter-molecular interactions. The coordination bonds (O…Sn) hydrogen (N─H…O) between MeC bridge lattice together, helping suppress Sn2+, meanwhile, restraining fast precursor solution, enhancing nucleation sites. More importantly, connection can reduce deep-level trap state defect density, significantly non-radiative recombination improving carrier lifetime. Consequently, this facile offers valuable insights into allows an enhanced power conversion from 10.43% 14.02% be achieved with good stability.

Abstract Formamidinium lead iodide (FAPbI 3 ) represents an optimal absorber material in perovskite solar cells (PSCs), while the application of FAPbI inverted‐structured PSCs has yet to be successful, mainly owing its inferior film‐forming on hydrophobic or defective hole‐transporting substrates. Herein, we report a substantial improvement ‐based inverted PSCs, which is realized by multifunctional amphiphilic molecular hole‐transporter, (2‐(4‐(10 H ‐phenothiazin‐10‐yl)phenyl)‐1‐cyanovinyl)phosphonic acid (PTZ−CPA). The phenothiazine (PTZ) based PTZ−CPA, carrying cyanovinyl phosphonic (CPA) group, forms superwetting hole‐selective underlayer that enables facile deposition high‐quality thin films. Compared previously established carbazole‐based (2‐(3,6‐dimethoxy‐9 ‐carbazol‐9‐yl)ethyl)phosphonic (MeO−2PACz), crystallinity enhanced and electronic defects are passivated PTZ−CPA more effectively, resulting remarkable increases photoluminescence quantum yield (four‐fold) Shockley‐Read‐Hall lifetime (eight‐fold). Moreover, shows larger dipole moment improved energy level alignment with , benefiting interfacial hole‐collection. Consequently, achieve unprecedented efficiency 25.35 % under simulated air mass 1.5 (AM1.5) sunlight. device commendable long‐term stability, maintaining over 90 initial after continuous operation at 40 °C for 2000 hours.
