Abstract

Dye-sensitized solar cells (DSSC) are fabricated with photoanode comprises of nanocomposite material of TiO2 and multi-walled carbon nanotubes (MWNT) treated in situ by plasma and subsequent functionalization by grafting of maleic anhydride (MA). The functionalized MWNTs enable the nanotubes to disperse homogenously among the TiO2 nanoparticles and become an integral part of the nanocomposites. As a result, MWNTs-MA/TiO2 nanocomposites presented obvious improvements in photocurrent and solar power conversion efficiency as the CNT provides efficient electron transfer through the film as well as the charge collection at the surface of counter electrode due to its excellent conductivity. At an optimum incorporation of 0.075wt.% MWNTs into the working electrode, the photo conversion efficiency of the DSSC was improved by more than 30%.
