电化学阳极氧化法制备的TiO 2纳米管阵列在染料敏化太阳能电池中表现出了令人印象深刻的光电转换效率。通过改变阳极氧化时间从2到20小时来控制TiO 2纳米管阵列的长度（5-14 μ m）。通过阻抗谱研究了纳米管长度对DSC光伏性能的影响。使用钛箔上的TiO 2纳米管阵列作为工作电极、聚萘二甲酸乙二醇酯（ITO/PEN）作为反电极并结合无溶剂离子液体电解质的柔性DSC在模拟AM 1.5阳光下实现了3.6%的光伏转换效率。
TiO2 nanotube arrays prepared by electrochemical anodization of Ti foils show impressive light to electricity conversion efficiency in the dye-sensitized solar cells (DSCs). The length of the TiO2 nanotube arrays (5-14 mu m) was controlled by varying the anodization time from 2 to 20 h. The influence of nanotube lengths on the photovoltaic performance of DSCs was investigated by impedance. A flexible DSC using TiO2 nanotube arrays on a Ti foil as a working electrode and polyethylene naphthalate (ITO/PEN) as counterelectrode in combination with solvent-free ionic liquid electrolyte achieved 3.6% photovoltaic conversion efficiency under simulated AM 1.5 sunlight.
