在本工作中，我们通过钛阳极氧化/蚀刻工艺制备了15μm厚的二氧化钛介海绵层（TMSL），并将其用于染料敏化太阳能电池（dsc）。我们表明，通过ticl4水解处理，太阳能电池的效率可以大大提高（增加约10%）。在am1.5照明下，40%至4.9%的整体值)。这种有益的效果是由于TMSL中存在的~ 10nm宽的通道被约为10nm的tio2纳米颗粒修饰。直径为3nm，这使得TMS结构的特定染料负载明显更高。
In the present work, we produce 15μm thick titania mesosponge layers (TMSL) by a Ti anodization/etching process and use the layers in dye-sensitized solar cells (DSCs). We show that the solar cell efficiency can considerably be improved by a TiCl4hydrolysis treatment (increase of approx. 40% to an overall value of 4.9% under AM 1.5 illumination). This beneficial effect is due to the decoration of the ∼10nm wide channels present in TMSL with TiO2nanoparticles of approx. 3nm diameter, which allow for a significantly higher specific dye loading of the TMS structure.
