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。 TiO2 nanowires are promising materials for the preparation of dye-sensitized solar cells (DSSCs) due to their rapid electron and light scattering due to their one-dimensional morphology. The length and dispersion of nanowires are the main factors affecting the efficiency of DSSC. TiO2 dispersed long nanowire gums were prepared which showed good scattering properties and did not hinder the absorption of dyes compared to commercial P200 gums and could enhance the performance of dye-sensitized cells when used as a light scattering layer in DSSCs. When the effective area of ​​DSSC with P25 / nanowire composite is 0.25 cm2, the photoelectric conversion efficiency reaches 5.73%. Compared with the DSSC of P25 / P200 composite and the DSSC of P25, the efficiency is obviously improved.
