Fabrication of electrospun BaTiO₃/chitosan/PVA nanofibers and application for dye-sensitized solar cells

Abstract

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.

Optical investigation and computational modelling of BaTiO3 for optoelectronic devices applications

“…Another work utilized BaTiO 3 in perovskite thin films but with Si-doping 25 and other dopants 30 . Moreover, BaTiO 3 recorded efficient integration in dye-sensitized solar cells, following data presented in 16,18,31,32 . Over and above, the UV absorption capability can be considered a credit in designing indoor light harvesters, where the UV portion in the light spectrum dominates 33,34 .…”
