摘要：

Partially nanowire-structured TiO2 was prepared by a hydrothermal processing followed by calcination in air. The hydrogen titanate powder as-synthesized was calcined at 300 degrees C for 4 h to obtain the partially nanowire-structured TiO2. A dye-sensitized solar cell (DSC) with a film thickness of 5.6 Mm, fabricated using the partially nanowire-structured TiO2 showed better performance than using a fully nanowire-structured TiO2 or a conventional equi-axed TiO2 nanopowder. The short-circuit current density (J(SC)), the open-circuit voltage (V-OC), the fill factor (FF) and the overall efficiency (eta) are 11.9 mA/cm(2), 0.754 V, 0.673 and 6.01 %, respectively. The effects of one-dimensional nanostructure and electron expressway concept are discussed. (C) Versita Warsaw and Springer-Verlag Berlin Heidelberg. All rights reserved.
