description | Nanostructured Titanium Dioxide (TiC^) thin film for Dye-Sensitized Solid
State Solar Cell (DSSSC) application has been synthesized using sol-gel method and
deposited onto silicon and glass substrates using spin coating technique. The
optimized annealing temperature and sol-gel concentration were obtained a| 500°C
and 0.2M, respectively. Basically, there were four properties studied; surface
morphology, structural, electrical and optical properties. Field Emission Scanning
Electron Microscopy (FE-SEM) / Scanning Electron microscopy (SEM) were carried
out to observe the changes in surface morphology whenever there are changes on the
parameters. X-Ray Diffractions (XRD) characterization of the samples was taken to
examine the TiC>2 crystalline phases and the intensity of nanocrystalline particles in
the thin film. I-V measurement using two-point probe equipment was used to observe
the electrical properties which include the measuring of the sheet resistance, the
resistivity and the conductivity of the TiC>2 thin film. The optical properties were
observed using UV-Vis-NIR spectrophotometer. The thin film transmittance and the
band gap energy were also observed using this spectrophotometer. At the end of this
research, uniform and homogeneous TiC>2 thin film has successfully prepared. By
controlling the sol-gel concentration, a transparent TiC>2 thin film has been developed
which has high transmittance property of above 80%. The TiC>2 thin films which
were annealed at a temperature of 500°C and prepared at 0.2M of sol-gel precursor
concentration gave the optimum results. By adding TiC>2 nanopowder, the surface
area and porosity of TiC>2 thin film is improved, thus good candidate to use in
DSSSC application. |
