ABSTRACT
This research is to fabricate Dye Sensitized Solar Cell (DSSC) based on ZnO
nanomaterials. One of the efforts to increase the efficiency of DSSC is by doping
the ZnO active material. ZnO nanomaterial doped with Niobium 0 wt%; 2.5 wt%
and 3.0 wt% is successfully synthesized using the hydrothermal method. The
results of the synthesis are analyzed using UV-Vis absorption spectroscopic
characterization, X-Ray Diffraction(XRD), Scanning Electron Microscope /
Energy Dispersive X-Ray (SEM-EDX) and I-V characterization. The UV-Vis
spectrum of the samples show that strong absorption is observed at a wavelength
of 230-325 nm. The sample XRD pattern at an angle of 2θ: 20º to 60º shows five
diffraction peaks at an angle of 2θ: 31.74º; 34.40º; 36.22º; 47.50º and 56.55º.
Analysis of the high score confirmes that the five peaks have crystal orientation
fields (100), (002), (101), (102) and (110). SEM photos depicts that the geometric
shape of the Nb-doped ZnO nanomaterial is nanorod with a hexagonal crosssection.
The sample EDX spectrum shows elements Zn, O and Nb. DSSC is
fabricated using active nanomaterials doped with Nb as the active material, dye
N719, liquid electrolyte and Platinum as a catalyst on counter electrodes arranged
like a sandwich structure compositions. The results of I-V measurements under
Halogen lamp ilumination of its intensity of 100 mW/cm2 resulted in the highest
efficiency of 0.18% for DSSC cells based on ZnO:Nb 2.5 wt%.
Keywords: ZnO Active Material, Niobium Doped, Material Characterization,
DSSC, DSSC Performance.
