Zinc oxide (ZnO) is a as the semiconductor material in dye-sensitized solar cell (DSSC). In this research, the structural and electrical properties of Zinc Oxide thin film doped with titanium dioxide (Ti02) has been investigated. The sample undoped ZnO and ZnO doped with 1wt%, 3wt%, 5wt%, 7wt% and 9wt% of Ti02 were prepared using solution immersion method. All samples have been characterized using X-Ray Diffraction (XRD), Ultraviolet Visible (UV-Vis) and Current-Voltage characterization (I-V). Diffraction peak for all samples from XRD result shows the presence of dominant ZnO phase at (002) plane with hexagonal wurtzite structure. The sample prepared with 5wt% of Ti02 has the highest transmittance range while the sample with 7wt% of Ti02 has the highest absorbance in UV analysis. The resistance value for all samples was obtained from the analysis of I-V curve. The resistance value is decrease as the concentration of Ti02 increase.
