Multi‐Site Synergistic Regulation Towards Highly Efficient and Stable Perovskite Solar Cells

ions compared to bifunctional ligands, effectively passivating defects, suppressing ion migration, and reducing nonradiative recombination. After 1,000 h of continuous maximum power point tracking, PSCs with D-pTSAD maintained 82.5% of initial PCE. This research underscores the potency of multisite coordination chemistry in elevating both performance and stability of PSCs.
