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.展开更多
