P-Phenylenediaminium iodide capping agent enabled self-healing perovskite solar cell.

ABSTRACT: In this study, p-Phenylenediaminium iodide (PDAI) is used to in-situ growth of 2D (PDA)₂PbI₄ perovskite layer between (FAPbI₃)_0.85(MAPbBr₃)_0.15 3D perovskite and CuSCN as a cheap hole transport layer. The results indicate that the incorporation of 5 mg mL^-1 PDAI leads to enlarged grain sizes, compact grain boundaries, reduced trap density, efficient charge extraction, and enhanced stability of perovskite film. Passivation of perovskite film with the appropriate amount of PDAI helps in achieving efficient perovskite solar cell with a PCE as high as 16.10%, a J_SC of 21.45 mA cm^-2, a V_OC of 1.09 V, and FF of 70.21%, with negligible hysteresis and excellent moisture stability which rem
