Managing Crystallization in Tin‐Lead Perovskite Solar Cells via Differential Chelating Coordination

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A chelation‐mediated crystallization strategy is developed for Sn–Pb perovskites using 1,10‐phenanthroline. Stronger coordination with Sn than Pb helps reconcile their mismatched crystallization behavior, leading to improved crystalline quality, fewer defects, and reduced oxidation.
