摘要：

Perovskite barium titanate nanorods/nanoparticles (BaTiO3 NRs/NPs) and reduced graphene oxide loaded barium titanate nanocomposite (BaTiO3 NRs/NPs-rGO NC) were synthesized by hydrothermal method and applied as photoanode materials in dye-sensitized solar cell (DSSC). The prepared perovskite nanomaterials were characterized by SEM, HRTEM, EDAX, XRD, XPS, PL and Raman techniques. The photovoltaic performance of DSSC fabricated using BaTiO3 NRs/NPs-rGO NC photoanode delivered a highest PCE of 5.92 %, which was almost twofold higher than the PCE of BaTiO3 NRs/NPs photoanode based DSSC (3.07 %). This improved photovoltaic performance could be attributed to superior light-harvesting and charge transportation behaviour of BaTiO3 NRs/NPs-rGO NC photoanode.
