本发明公开了种用于染料敏化太阳能电池的TiO纳米管阵列，该TiO纳米管阵列为金属Cu掺杂改性的TiO纳米管阵列，且具有DNA螺旋状或筛网状的三维纳米结构。本发明还公开了该Cu掺杂TiO纳米管阵列的制备方法，通过电化学阳极氧化法，直接在铜钛合金丝基体构筑的具有DNA螺旋结构或筛网结构的基体上生长出具有三维结构、且具有较强可见光响应性能的TiO纳米管阵列。本发明制备的Cu掺杂改性TiO纳米管阵列及三维结构，有效拓展了TiO的禁带宽度，增加了TiO纳米管阵列的比表面积，从而能够显著提高TiO半导体对染料的吸附能力并获得对太阳光的高效吸收，有利于染料敏化纳米晶TiO太阳能电池光电转换性能的改善。该方法工艺简单、成本低廉、可控程度高。
