英文摘要	The seven kinds of natural dyes were extracted from flowers, leaves, fruits and peels, and were measured their optical absorption characteristics by U-2001 spectrophotometer. By comparison, it was found that the natural dye extracted from leaves of Chinese rose showed better performance of the light response. Nano-crystalline Zn2TiO4 film electrode were prepared by sol-gel method and were characterized by XRD and SEM. Using the natural dye extracted from leaves of Chinese rose as sensitizers, the natural dye sensitized Zn2TiO4 electrode was prepared, and the natural dye sensitized Zn2TiO4 solar cell device was fabricated. The absorption spectra of the sensitized electrode was characterized by Uv-2550 spectrophotometer, the result showed that the UV-Vis absorption bands of the adsorbed dyes onto Zn2TiO4 film are broadened and the corresponding maxima are red shifted with respect to its solution, and the natural dye presented a little ability of electron transfer and could well sensitize Zn2TiO4 film electrode. Current potential curve for the natural dye sensitized solar cell was tested under simulation sunlight, encouraging results were obtained with the extract of leaves of Chinese rose, achieving an open-circuit voltage of 94.5 mV, a short-circuit photocurrent of 11.5 μA, a fill factor of 0.285 and a maximum power output of 0. 309 μW.
