The electron lifetimeand cell conversion efficiency could be improved significantly by adding MWCNTs in the TiO2 electrode. Thisprocess could also reduce the electrode crack and enhance the mechanical strength of electrode. The use of carbonnanoparticles and CNTs as the counter electrodes to replace Pt could reduce the cost of cells, and enhance theelectrochemical activity of electrode and the cell conversion efficiency. The composite film of new carbon materialsand the other material could improve the mechanical property and the environment stability. The influence ofpreparation technology of materials, the MWCNTs percentage on the cell performance and the performance ofelectrode composed of single wall carbon nanotube(SWCNT) and Ag were also be discussed.
