ZnO/TiO2 particles were investigated for dye-sensitized solar cells (DSSC). Nano-structured ZnO particles were produced by the hydrothermal method. TiO2 (P25) nanoparticles, was bought from the company of Degussa. Crystal structures and morphological properties of particles were examined by XRD and SEM. As an application, dye sensitized solar cells were fabricated from nano-structured produced metal oxide particles. The working electrodes of the DSSCs were obtained by mixture of ZnO and TiO2 powders. I-V characteristics of the cells were measured by using a solar simulator and the efficiency of the solar cells were obtained by using I-V graphs. ZnO cells sensitized with Ruthenium 535-bisTBA (N719) dyes yield higher efficiencies than corresponding TiO2 cells. By increasing TiO2 amount in the mixture of ZnO/TiO2, it was observed that efficiencies of cells are getting lower.
