Synthesis and characterization of flower like ZnO nanorods for dye-sensitized solar cells
Flower like ZnO nanorods have been prepared by chemical bath deposition method. X-ray diffraction result shows that flower like ZnO nanorods exhibit hexagonal structure. Dye sensitized solar cells have been assembled by using ZnO nanorod film photoelectrode sensitized using natural dye extracted from daucus carota as sensitizer. The flower like ZnO nanorods have been used as photo-anode material to fabricate the dye sensitized solar cell which exhibited an overall light to electricity conversion efficiency of 0.78 % with a fill factor of 0.39, short-circuit current density of 3.70 mA/cm2 and open-circuit voltage of 0.26 V.
