Bidentate coordination-induced trap passivation and phase stability in perovskite solar cells <i>via</i> ionic liquid engineering
The dicyanamide anion (DCA) stabilizes perovskite films by suppressing trap formation and δ-phase degradation, leading to enhanced phase integrity under operation. Devices exhibit improved PCE, moisture resistance, and long-term stability.
