Improved performance of dye-sensitized solar cells with TiO2nanocrystal/nanowires double-layered films as photoelectrode

Author affiliations

Abstract

A double-layered (DL) photoanode is fabricated based on TiO2 nanowire (NW) arrays coated by TiO2 nanocrystal (NC) films on their top. The highest efficiency of the obtained double-layered photoanode cells is ∼4.67% with 8 μm-long NW arrays and 6 μm-thick NC films. This efficiency is much higher than that of the devices with the pure TiO2 NC films or the pure TiO2 NW arrays as electrodes due to the synergistic effect of the dye adsorption and the rapid electron transport of NWs/NC structure.
