摘要	ZnO seed layers were prepared by sol-gel method and spin coating method on the substrate which is FTO/glass. The prepared substrates with seed layer were immersed into the precursor solution which contains zinc nitrate and hexamethylenetetramine (HMT) under different growth time and solution concentrations. The ZnO nanorod electrodes were characterized by XRD and SEM. We obtain orderly ZnO nanorod array at 90°C with growth time of 4 h, the solution concentration of 0.025 mol/L, and the average diameter about 80 nm. Using the natural dye extracted from fresh strawberries and mulberries as sensitizers, the natural dye sensitized ZnO nanorod film electrodes were prepared and the dye sensitized solar cells were fabricated. The absorption spectra of sensitized electrodes were characterized, and the result shows that the electrode with mulberries as sensitizer has a good absorbance in visible light area. In simulation, the solar cell with mulberries as sensitizer has excellent photoelectric characteristics, a filling factor of 0.37, a short-circuit photocurrent of 189 μA, an open-circuit voltage of 228.75 mV, and an optic-electric conversion efficiency of 5.5×10-4.
