This paper is focused on manufacturing of semiconductor nanorod-TiO₂ film for dye-sensitized solar cell applications. In order to create effective TiO₂/dye/electrolyte interfaces for the newly developed photoelectrode, it is necessary to investigate how to control 3D morphology of the porous TiO₂ layers on FTO substrate via thermal sintering of a water-based TiO₂ nanofluid consisting of bundle-shaped TiO₂ particles. The TiO₂ nanoparticles were deposited on FTO glass substrate, using spin coater. The nanoparticles were reshaped to 1D nanorod morphology and fused to enhance the electron collection efficiency of TiO₂ photoanode. The mixture of bundle-shaped TiO₂ and spherical-TiO₂ nanoparticles was sintered thermally to (a) fuse the TiO₂ nanoparticles together, (b) systematically change their assembly process by changing the sintering profiles.
