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.
