2D-MXene as an additive to improve the power conversion efficiency of monolithic perovskite solar cells

In this study, two-dimensional (2D) material-MXene has been utilized as an additive in perovskite (MAPbI3) from 0 to 20 vol.% with an increment of 5 vol.%. The effect of different vol.% of 2D-MXene on monolithic perovskite solar cells (mPSCs) has been investigated in detail through various characterization techniques such as X-ray diffraction (XRD), Raman Spectroscopy, and Field emission scanning electron microscopy (FE-SEM). The best device, perovskite with 5 vol.% 2D-MXene has shown a 13.62% power conversion efficiency (PCE) compared to the perovskite without 2D-MXene PCE of 11.35%.
