Perovskite BaTiO₃ nanoparticles were synthesized by a hydrothermal method. BaTiO₃/ chitosan (CS)/ Polyvinyl alcohol (PVA) nanofibers with an average diameter of 265.3 ± 52 nm were fabricated via an electrospinning method. The nanofibers were characterized by scanning electron microscope (SEM), X-ray diffraction (XRD), Fourier transformation infrared spectroscopy (FTIR), and thermal analysis method (TGA). The photoanodes of dye-sensitized solar cells (DSSC) were fabricated based on the BaTiO₃/CS/PVA nanofibers. The photovoltaic properties of the cells were calculated based on the current density – voltage curves. The maximum power conversion efficiency of DSSC with CS/PVA/ BaTiO₃ nanofibers was 0.49% with the natural dye sensitizer extracted from the leaf of the magenta plant.
