Abstract
A simple solution process was employed to decorate WO3 nanoparticles on 2D conductive Ti3C2TX MXene sheets to arrange the MXene/WO3 hybrid structure. The prepared hybrid composites were established by the Raman scattering, X-ray diffraction, and microscopy studies evidently. The designed hybrid structure, for the first time, was engaged with PEDOT:PSS to alter the hole transport layer (HTL) of perovskite hybrid module for the highly efficient planar solar cell and X-ray detector. The derived outcomes revealed a high power conversion efficiency of 12.26 ± 0.12% for the constructed perovskite solar cell with MXene/WO3/PEDOT:PSS HTL. Similarly, the fabricated X-ray photodetector with MXene/WO3 blended HTL device attained a superior sensitivity of 3.67 ± 0.03 mA Gy−1·cm−2. The results envisaged that HTL/perovskite interface was effectively tuned by the MXene/WO3 heterostructure through their active interface for transfer/collection of charges and appropriately altered energy band alignment, which gave the nod for easy to charge extraction and shortest charge carrier lifetime.
