The root of this issue lies in the initial heterogeneity of the mixed\u2010cation perovskite films, which accelerates localized phase segregation and defect proliferation under light and electrical stress. Current solutions balancing halide\u2010Pb\n                    <jats:sup>2+<\/jats:sup>\n                    interactions with additives commonly fail to resolve the intrinsic cation\u2010PbI\n                    <jats:sub>2<\/jats:sub>\n                    affinity disparity; moreover, additives are typically insulating, creating charge transport bottlenecks at grain boundaries. Herein, we developed a coordination\u2011chemistry\u2011based crystallization kinetics modulation strategy using 4,4\u2032\u2011dichlorodiphenyl sulfone (DCPSO). It balances the disparate crystallization kinetics of components with varying coordination capacities, yielding a highly uniform initial phase distribution that fundamentally suppresses degradation pathways from compositional heterogeneity. Additionally, the D\u2010\u03c0\u2010A conjugated structure of DCPSO provides good conductivity, alleviating carrier accumulation at grain boundaries and optimizing energy level alignment. The champion device achieves a\n                    <jats:italic>PCE<\/jats:italic>\n                    of 25.75% with excellent long term operational stability. Through molecular design, this work enables synergistic regulation of crystallization kinetics and electrical properties, offering an effective materials strategy and mechanistic insights to simultaneously tackle efficiency and stability challenges.\n
