摘　　要：Rutile TiO2 nanowire array films with multi-walled carbon nanotube （MWCNT） inclusion perpendicularly grown on fluorine-doped tin oxide （FTO） substrate were prepared by a facile hydrothermal method. The absorption edges of the TiO2 nanowire array films are blue-shifted with increasing MWCNT content. The resistance of the TiO2 nanowire array film is decreased by MWCNT inclusion. The optimum TiO2/MWCNT molar ratio in the feedstock is 1：0.1. For the TiO2 nanowire array film with MWCNT inclusion served as electrode in dye-sensitized solar cell （DSSC）, an overall 194% increase of photoelectric conversion efficiency has been achieved.Rutile TiO2 nanowire array films with multi-walled carbon nanotube （MWCNT） inclusion perpendicularly grown on fluorine-doped tin oxide （FTO） substrate were prepared by a facile hydrothermal method.
