Dye sensitized solar cells were fabricated using natural dyes extracted from beetroot, rose and strawberry. The ZnO nanorod working electrode has been prepared by simple hydrothermal method. The crystallinity and morphology of the prepared electrode has been studied using X-ray diffraction and scanning electron microscopy techniques. The effect of natural dye extract temperature, pH of the dye and the solvent used for dye preparation on the solar cell characteristics have been studied. The efficiency of strawberry extract sensitized ZnO nanorod solar cells are found to be better than the other solar cells sensitized using beetroot and rose extracts.
