Abstract

One-dimensional nanofibers fabricated by the process of electrospinning have found engaging applications in the field of dye sensitized solar cells (DSSC) due to semi-directed electron transport. Current research accounts for the development of conductive mats made from nanofibers, which is achieved through the electrospinning of TiO2–ZnO composites and by using polyvinylpyrrolidine as a carrier solution. This fiber was annealed at 450 °C to attain a continuous network of conducting nanofibers. ZnO from the composite was selectively etched to fabricate high surface area anisotropic TiO2 hierarchical fiber. Morphological and phase analysis conducted by scanning electron microscopy and X-ray diffraction studies confirmed the formation of anatase phase and 1-D hierarchical morphology of TiO2. These structures were employed as photoanodes in DSSC, which had shown superior photoconversion efficiency.
