Abstract

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.
