Nanoparticles of TiO 2 have been the main semiconductor applied in dye-sensitized solar cells. However, with the progress made in the nanotechnology field, new semiconductors with varied morphologic characteristics are been broadly investigated. In this thesis work titanate nanotubes (NaTiNT) and nanoribbons, were obtained by the hydrothermal method from TiO 2 anatase. These materials were deposited on conductive substrate by electrophoresis, with and without thermal treatment, sensitized by ruthenium-based dye and used as work electrode. Exposing those photovoltaic devices to visible radiation, with films before thermal treatment, a short-circuit current density (J SC ) of 0.0012 mA/cm 2 was observed for the cell with NaTiNT, a current de...
