论文摘要
在目前的工作中，我们种植了阳极Tio $ _2 $纳米管层，管直径〜500 nm和开放的管嘴。我们在染料敏化的太阳能电池（DSSC）中使用这种形态，并表明这些试管允许纳米管的混合层次光轴模结构具有定义的和壁构成TiO2纳米颗粒装饰。同时，大直径允许成功建立SIO $ _2 $或Al $ _2 $ o $ $ _3 $的额外（绝缘）阻塞层。我们表明，分层结构和阻塞层的这种组合通过抑制重组反应可显着提高太阳能电池效率。在这样的DSSC结构中，带有AM1.5照明的后侧照明下的太阳能电池效率从5％整齐的管升至7％。
In the present work we grow anodic TiO$_2$ nanotube layer with tube diameter ~ 500 nm and an open tube mouth. We use this morphology in dye-sensitized solar cells (DSSCs) and show that these tubes allow the construction of hybrid hierarchical photoanode structures of nanotubes with a defined and wall-conformance TiO2 nanoparticles decoration. At the same time, the large diameter allows the successful establishment of an additional (insulating) blocking layer of SiO$_2$ or Al$_2$O$_3$. We show that this combination of hierarchical structure and blocking layer significantly enhances the solar cell efficiency by suppressing recombination reactions. In such a DSSC structure, the solar cell efficiency under back side illumination with AM1.5 illumination is enhanced from 5% neat tube to 7 %.
