染料敏化太阳能电池（DSSC）可将太阳光转化为电能，有望成为当今世界有前途的可再生能源。在这项工作中，制造了染料敏化太阳能电池，一种包含单层，另一种包含双层。在双层 DSSC 结构中，下层为 TiO2-P25 薄膜，顶层由 TiO2-P25 和 TiO2 纳米管的混合物组成。结果表明，与仅由单膜层组成的 DSSC 相比，双层结构的 DSSC 的效率有显着提高。在顶层添加 TiO2-P25 可以改善染料分子在薄膜上的吸附，而不仅仅是在 TiO2 纳米管上。顶层中 TiO2 纳米管与 TiO2-P25 的存在揭示了入射光收集的增强以及通过薄膜的电子传输的改善。 (C) 2016 中国材料研究会出版。
The dye sensitized solar cell (DSSC), which converts solar light into electric energy, is expected to be a promising renewable energy source for today's world. In this work, dye sensitized solar cells, one containing a single layer and one containing a double layer, were fabricated. In the double layer DSSC structure, the under-layer was TiO2-P25 film, and the top layer consisted of a mixture of TiO2-P25 and TiO2 nanotubes. The results indicated that the efficiency of the DSSC with the double layer structure was a significant improvement in comparison to the DSSC consisting of only a single film layer. The addition of TiO2-P25 in the top layer caused an improvement in the adsorption of dye molecules on the film rather than on the TiO2 nanotubes only. The presence of the TiO2 nanotubes together with TiO2-P25 in the top layer revealed the enhancement in harvesting the incident light and an improvement of electron transport through the film.
