doi:10.7517/j.issn.1674-0475.2008.03.224

Abstract

Abstract: The titania nanotubes were synthesized by hydrothermal process. TiO₂ nanotubes were characterized by means of TEM, XRD and nitrogen adsorption-desorption isotherms. The TiO₂ thin film electrodes were prepared by the titania nanotubes and P25, the surface morphologies, dye loading and photoelectric performance of the film electrodes were analyzed. It is found that the film electrodes are mechanical stable with the addition of the titania nanotubes, The more titania nanotubes film electrodes contain, the higher dye they absorb. When the content of titania nanotubes is 5%, the best photoelectric performance of the film electrodes can be achieved. Its short circuit current of flexible DSSC is 3.25 mA with 1.67% solar-to-electric energy conversion efficiency.

Key words: titania nanotubes, hydrothermal method, TiO₂ thin film electrode, flexible DSSC, photoelectric performances
