Well-dispersed NH2-MWCNTs-TiO2 nanocomposite were modified on fluorine-doped tin oxide (FTO) glass. Then we change the contain of NH2-MWCNTs doped in TiO2 nanocrystalline matrix and alter the film thickness of NH2-MWCNTs(0.025 wt%)-TiO2 nanocomposite photoelectrde. The distribution of NH2-MWCNTs in TiO2 matrix and the film thickness of NH2-MWCNTs-TiO2 nanocomposite were investigate by field emission scanning electron microscopy (FESEM). The adsorption of dye-sensitizer on the working electrode were characterized by Ultraviolet-Visible spectroscopy (UV-Vis). UV-Vis spectrum reveal more higher absorbance on NH2-MWCNTs-TiO2 nanocomposite photoelectrode than the others. The charge resistance in the DSSC was characterized by electrochemical impedance spectroscopy (EIS). EIS results exhibit a decrease in the charge resistance of electrolyte/dye/NH2-MWCNTs-TiO2 interface with increasing NH2-MWCNTs contents which leads to an improvement in the photovoltaic performance up to 0.025 wt%. Compare with the nanocrystalline TiO2 DSSCs, the NH2-MWCNTs (0.025 wt%)-TiO2 nanocomposite photoelectrode in DSSCs shows ~76 % increase in solar-to-electric energy conversion efficiency, which is attributed to the inclusion of NH2-MWCNTs in TiO2 network.
