New application of electrospun TiO2 nanofibers as an electrode for dye-sensitized solar cell

Abstract

The electrospun TiO2 nanofibers were employed to the quasi-solid state dye-sensitized solar cells with porous electrodes which enhanced the penetration of viscous polymer gel electrolytes. The TiO2 fibers electrospun from poly(vinyl acetate) matrix formed the one-dimensionally aligned fibrillar morphology as a bundle of nanorods. The new TiO2 electrodes demonstrated that the photocurrent generation with polymer gel electrolytes was over 90% of the performance in DSSC with liquid electrolytes.
