Abstract
Perovskite Solar Cells In article number 2000481, Runfeng Chen and co-workers employ commercially available pyridinedicarboxylic acid (PDA) as a novel passivating agent to cure various defects of perovskite microstructures. Benefiting from the multiple coordination feature of PDA molecules, high power conversion efficiency and good long-term and thermal stabilities are achieved in the PDA-passivated inverted perovskite solar cells.
