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 The rapid development of the Internet Things (IoT) has accelerated advancement indoor photovoltaics (IPVs) that directly power wireless IoT devices. interest in lead‐free perovskites for IPVs stems from their similar optoelectronic properties to high‐performance lead halide perovskites, but without concerns about toxic leakage environments. However, currently prevalent perovskite IPVs, especially tin (THPs), still exhibit inferior performance, arising uncontrollable crystallization. Here, a novel adhesive bonding strategy is proposed precisely regulating heterogeneous nucleation kinetics THPs by introducing alkali metal fluorides. These ionic adhesives boost work adhesion at buried interface between substrates and film, subsequently reducing contact angle energy barrier nucleation, resulting high‐quality THP films. solar cells achieve an efficiency 20.12% under illumination 1000 lux, exceeding all types successfully powering radio frequency identification‐based sensors.

Herein, two kinds ligands 1, 4‐cyclohexyldimethylammonium diiodide (CyDMADI) and 4‐phenyldimethylammonium (PhDMADI) are introduced into precursor for bulk passivation. The PhDMADI system exhibits a stronger unit comparison CyDMADI core, thus resulting enhanced electrostatic interaction between uncoordinated Pb 2+ groups hydrogen bonds I─Pb skeleton. Such strengthened interactions effectively inhibit generation trap states therefore significantly decrease non‐radiative recombination. PhDMADI‐passivated film demonstrates mitigated microstrain decreased grain boundary grooves （GBGs） compared CyDMADI‐based counterpart. Simultaneously, treatment can efficiently slow down hot‐carriers cooling dynamics process, benefiting transfer hot‐carriers. Consequently, achieves an impressive efficiency 26.04%, along excellent operating stability which retains 90% its initial after 1100 h tracking at maximum power point under continuous one sun illumination.
