摘　　要：TiO2纳米线因其一维形态所致的快速电子传导及光散射而成为制备染料敏化太阳电池(DSSC)的一种具有良好潜能的材料。纳米线的长度及分散性是影响DSSC效率的主要因素。制备出了TiO2分散长纳米线胶,其显示出良好的散射性能,与商业P200胶相比,不妨碍染料的吸收,用作DSSC中的光散射层时可提高染料敏化电池性能。采用P25/纳米线复合材料的DSSC有效面积为0.25 cm2时,光电转化效率达到了5.73%,与P25/P200复合材料的DSSC及P25的DSSC相比,效率有明显提高。The TiO2nanowire（NW）is regarded as the potential material for the fabrication of the dye-sensitized solar cell（DSSC）because of the fast electron conduction and light scattering caused by its one-dimensional morphology.The length and dispersion of the nanowire are the main factors affecting the efficiency of the DSSC.A kind of dispersed long TiO2 nanowire paste was prepared,which exhibited excellent scattering properties and had no effect on the dye adsorption compared with the commercial P200 paste.Moreover,the performance of the DSSC was improved when the TiO2 nanowire paste was used as the light scattering layer in the DSSC.When the active area of the composite DSSC using TiO2 P25/NW was 0.25 cm2,the photo electric conversion efficiency of 5.73% was achieved,and which was greatly enhanced compared with those of the P25/P200 composite DSSC and P25 DSSC.
