Abstract
In this work it was presented a direct formation of anatase TiO2 nanotube by titanium powder using, as source material. TNT was prepared by hydrothermal synthesis method using with successive acid and heat treatment. This method proves a new route to fabricate DSSC with high electron to photon conversion efficiency. The phase identification of the samples was conducted with powder X-ray diffraction (XRD). The morphologies and structure of samples were observed through SEM and TEM. The results of the investigation showed that the anatase TiO2 nanotubes have the outer diameters of around 10 nm. We fabricated DSSC with this well-aligned one-dimensional (1-D) titania nanotubes (TNT) on indium tin oxide (TCO) by doctor blading technique. The fabricated TNT photoelectrode showed 1.64% efficiency whereas the composite photoanode with the mixture of TNP + 30% TNT gives 2.06%. This method will surely be an exciting addition to the fast growth family of synthesis of oriented TiO2 nanotubes.
