Abstract

A post-treatment strategy utilizing N-(2-fluoropyridin-6-yl)-2-(4-amino-4-formamido-1H-pyrazol-2-yl)acetamide (FPA) was developed to simultaneously leverage the synergistic benefits of surface passivation and secondary grain growth regulation, thereby achieving a high efficiency of 26.01%—among the highest reported for air-processed perovskite solar cells (PSCs) to date.
