Solvent-Regulated Surface Passivation for Efficient and Stable Inverted Perovskite Solar Cells

Phenethylammonium iodide (PEAI) is widely used to passivate undercoordinated ionic defects and regulate the near-surface structure of inverted perovskite solar cells; however, the solvent used for PEAI deposition can also interact with the underlying perovskite and therefore determine the treatment outcome. Here, ethan...
