TiO2 rutile nanowire electrodes for dye-sensitized solar cells

Abstract We synthesize the TiO 2 nanowire electrodes via hydrothermal process without addition of any surfactant as a function of reaction time. The short-circuit current density and cell efficiency of the TiO 2 nanowire electrodes in DSSC increase with decreasing reaction time. In particular, the rutile nanowire electrodes show an improved open-circuit voltage due to an increased electron lifetime in one-dimensional electrode.
