Large-sized titanium dioxide (TiO2) nanotube arrays with an outer diameter of approximately 500 nm have been successfully synthesized by potentiostatic anodization at 180 V in a used electrolyte with the addition of 1.5 M lactic acid. It is found that the synthesized large-diameter TiO2 nanotube array shows a superior light scattering ability, which can be used as a light scattering layer to significantly enhance the efficiency of TiO2 nanoparticle-based dye-sensitized solar cells from 5.18% to 6.15%. The remarkable light scattering ability makes the large-diameter TiO2 nanotube array a promising candidate for light management in dye-sensitized solar cells (DSSCs).
已成功通过在 180V 下在含有 1.5M 乳酸的电解液中进行恒压阳极氧化,合成出具有约 500nm 外径的大尺寸二氧化钛(TiO2)纳米管阵列。研究发现,所合成的大直径 TiO2 纳米管阵列具有优异的光散射能力,可用作光散射层,可将基于 TiO2 纳米颗粒的染料敏化太阳能电池的效率从 5.18%显著提高至 6.15%。其优异的光散射能力使大直径 TiO2 纳米管阵列成为染料敏化太阳能电池(DSSCs)中的一种有前途的用于光线管理的候选材料。
