TiO₂-Anatase Nanowire Dispersed Composite Electrode for Dye-Sensitized Solar Cells

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.
