摘　　要：首先采用浸渍提拉法在导电玻璃上涂TiO2溶胶膜并烧结,再用P25粉制备TiO2浆料涂敷在溶胶膜上烧结制备成DSSC光阳极。对光阳极的双层膜结构进行XRD、FESEM等表征分析,并对相应的DSSC测试电池性能。采用正交实验设计,考查溶胶提拉次数、P25涂敷层数、在溶胶中加入乙基纤维素(EC)的含量等3个因素对DSSC性能的影响。结果表明,溶胶提拉10次,P25涂敷一层,不加EC时,电池性能最佳;P25层数对开路电压有重大影响。In this article, the photoanode for the dye-sensitized solar cell （DSSC） was prepared with titanium oxide sol film by dip-coating method and titanium oxide （Degussa P25 powders） paste prepared by doctor-blade method. The characterization of the sol and P25 film were measured using XRD and FESEM. The effect of the coating times of the dip-coating sol, the layers of P25 powders and the content of the ethly cellulose in the sol, on the properties of DSSC was studied by the orthogonal experiment. It is concluded that the cell achieved highest properties under the preparation condition as ten times of dip-coating sol, one layer of P25 and no EC additive. It is also found that the layer numbers of P25 has significant effect on the open circuit voltage.
