Abstract

TiO films with a three-dimensional web-like porous structure were prepared using the photo polymerization-induced phase separation method integrated with the pulling coating process. By adjusting the ratio of the substance in the precursor sol and the coating times, the relationships between the sol ratio, the coating times, the film structure, and the performance of the DSC were studied. The optimal film structure was found and a detailed description is given. The performance of the DSC was further improved by introducing the barrier layer and the surface-modified layer of the TiO coating. This promoted the short-circuit current density and the photoelectric conversion efficiency of the DSC, the mechanism of which was also investigated. Ultimately, the photoelectric conversion efficiency of the DSC based on the TiO anode films with a three-dimensional web-like structure was stabilized at a higher level as a result of the structural improvement.

摘要

采用光聚合诱导相分离法结合提拉镀膜工艺制备了具有三维网状多孔结构的TiO薄膜。通过调整前驱体溶胶中物质的比例和镀膜次数，研究了溶胶比例、镀膜次数、薄膜结构与染料敏化太阳能电池（DSC）性能之间的关系。找到了最佳的薄膜结构并给出了详细描述。通过引入TiO涂层的阻挡层和表面改性层，进一步提高了DSC的性能。这提高了DSC的短路电流密度和光电转换效率，同时也研究了其机理。最终，由于结构改进，基于具有三维网状结构的TiO阳极薄膜的DSC的光电转换效率稳定在较高水平。
