Abstract

A high open-circuit voltage dye-sensitized solar cell (DSSC), based on a ZnO/TiO₂ nanocomposite (NC) photoelectrode, was presented. This NC photoelectrode was composed of density-controlled ZnO-TiO₂ core-shell nanorod arrays and dispersed TiO₂ nanoparticles. The electrochemical impedance spectroscopy results confirmed that a reduced recombination loss was achieved by applying the proposed composite nanostructure. Thus, a higher open-circuit voltage of up to 0.93 V was achieved.
