在本工作中，通过将两端开放的有序独立的二氧化钛纳米管(TNT)阵列的透明电极转移到氟掺杂的氧化锡(FTO)导电玻璃上，制备了染料敏化太阳能电池(DSSCs)。本文所用的高质量的二氧化钛膜是通过自分离技术获得的，具有工艺简单但可靠的优点。然后，这些TNT膜可以很容易地通过二氧化钛纳米颗粒浆料转移到FTO玻璃基板上，而不会出现任何裂纹。与由底部封闭的膜或附着在钛衬底上的DSC相比，精心组装和正面照明的DSC在没有进一步处理的情况下，太阳能转换效率比24μm厚的Ti02纳米管膜提高了5.32%。这些结果表明，通过促进高质量的膜合成，这种具有优化管状结构的DSSCs组装具有广阔的前景。
In the present work, dye-sensitized solar cells (DSSCs) were fabricated by incorporating transparent electrodes of ordered free-standing TiO2 nanotube (TNT) arrays with both ends open transferred onto fluorine-doped tin oxide (FTO) conductive glass. The high-quality TiO2 membranes used here were obtained by a self-detaching technique, with the superiorities of facile but reliable procedures. Afterwards, these TNT membranes can be easily transferred to FTO glass substrates by TiO2 nanoparticle paste without any crack. Compared with those DSSCs consisting of the bottom-closed membranes or attached to Ti substrate, the carefully assembled and front-side illuminated DSSCs showed an enhanced solar energy conversion efficiency as high as 5.32% of 24-μm-thick TiO2 nanotube membranes without further treatments. These results reveal that by facilitating high-quality membrane synthesis, this kind of DSSCs assembly with optimized tube configuration can have a fascinating future.
