Me-4PACz Functionalized MXene for Halide Perovskite Solar Cells.

ABSTRACT: Interfacial passivation employing 2D Ti₃C₂ MXenes has proved to be an excellent strategy to optimize band alignment and passivate defects, leading to the reduction of non-radiative recombination in Perovskite Solar Cells (PSCs). Here in, the synthesis and functionalization of Ti₃C₂ MXene are reported with the [4-(3,6-Dimethyl-9H-carbazol-9-yl)butyl]phosphonic acid molecule (MXene:Me-4PACz), which is proved by XRD and HRTEM-EELS analyses. Its application at the interface between the halide perovskite (HP) and the Spiro-OMeTAD in normal configuration PSCs, results in the enhancement of indoor and outdoor stability. The MXene:Me-4PACz nanomaterial is obtained in the form of nanoneedles, which, applied in complete PSCs, resulted in a power conversion
