Synthesis of garland like ZnO nanorods and their application in dye sensitized solar cells

Garland like ZnO nanorods have been synthesized by the chemical bath deposition method. Dye sensitized solar cells have been assembled by using natural dye extracted from hibiscus rosasinensis as sensitizer in garland like ZnO nanorod films. X-ray diffraction result shows that garland like ZnO nanorods exhibit hexagonal structure. The ZnO nanorods have an average diameter of 100 nm and the length of the nanorods is 2 μm. The efficiency of the fabricated dye sensitized garland like ZnO nanorod based solar cell is 0.67%.
