Abstract

Summary: A simple solution process was employed to decorate WO3 nanoparticles on 2D conductive Ti3 C2 TX 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. Abstract : For the first time, MXene/WO3 blended PEDOT:PSS hole transport layer comprised devices were assembled. A high power conversion efficiency of 12.26% was achieved by MXene/WO3 embedded PEDOT:PSS HTL comprised PSC device. A supreme CCD‐DCD of 12.62 μA cm −2 and an excellent sensitivity of 3.67 mA Gy −1 cm −2 were realized by the MXene/WO3 (2 wt%)@PEDOT:PSS HTL comprised X‐ray detector.
