TiO2-Anatase nanowire dispersed composite electrode for dye-sensitized solar cells

Abstract

TiO2 anatase nanowires have been prepared by a hydrothermal process followed by post-heat treatment in air. TiO2 nanoparticle/TiO2 nanowire composite electrodes were prepared for dye-sensitized solar cells (DSC) in order to improve light-to-electricity conversion efficiency. The TiO2 NP/TiO2NW composite cells showed higher DSC performance than ordinary nanoparticle cells and fully nanowire cells: efficiency (η 6.53 % for DSC with 10% nanowire, whereas 5.59% for 0% nanowire, and 2.42% for 100% nanowire. © 2007 IOP Publishing Ltd.
