Natural dyes were extracted from 29kinds of natural plants using ultra sonic method.Uv-vis absorption spectra of these natural dyes were tested and pigments contained in these natura l dyes were discussed.TiO_2film electrodes were prepared by hydrothermal method,TiO_{2photoelectrodes} were sens itized by 29kinds of natural dyes and then they were fabricated to dye sensitized solar cells (DSSCs).The photoelectri c performance of DSSCs sensitized by these dyes was tested.The experimental results indicate that the open circuit voltages (Voc) vary from 0.46V to 0.64V and the short circuit photocurrent densities (I sc) range from 0.04mA·cm－2 to 3.61mA·cm－2. Specifically,the DSSC sensitized by mangosteen pericarp dye has optimum photoel ectric performance,whose short circuit photocurrent density and photoelectric conversion efficiency (η) are 3.61mA·cm－2 and 2.13%,respectively.Seven kinds of dyes with different absorption bands of pigment wer e picked out and mixed with each other for Collaborative sensitizer.UV-vis abso rption spectra show that absorption peaks of these mixed dyes usually have a small offset.The test results of photoelectric properties s how that the photoelectric conversion efficiency of DSSC sensitized by mixed natrual dyes is between those of DSSCs se nsitized by single natural dyes.The photoelectric conversion efficiency of DSSC sensitized by mangosteen pericarp an d kale reaches the highest value of 1.7%.Finally,the experimental results are analzsed carefully and the way to improve the photoeletric performance of DSSCs sensitized by natu ral dyes is discussed.
