采用直流磁控溅射-热处理二步法在多孔阳极氧化铝模板上制备出 TiO2纳米管阵列膜。将纳米管阵列膜转移到 ITO 导电玻璃，并分别与 P3 HT 和P3 HT∶PCBM组装成杂化太阳能电池。通过扫描电镜、X射线衍射仪、能谱仪和模拟太阳光光电性能测试系统化对TiO2纳米管阵列膜和其组装的太阳能电池进行了分析表征。在纳米管阵列膜和 ITO 玻璃之间加入TiO2结合层的 P3 HT∶PCBM基杂化太阳能电池表现出最好的转换效率。该方法制备的大面积TiO2纳米管阵列膜，纯度高、工艺稳定，在未来的聚合物太阳能电池商业化应用中具有巨大潜力。
TiO2 nanotube arrays were made by DC magnetron sputtering-heat treatment two step method. Then,the nanotube arrays were transferred onto the ITO substrates,and were fabricated to hybrid solar cells with P3 HT and P3 HT∶PCBM,respectively.Scanning electron microscopy,X-ray diffraction,energy disper-sive spectrometer and photovoltaic measurement system were used to characterized and analyzed the TiO2 nano-tube arrays and the corresponding solar cells.The best conversion efficiency was obtained from the P3 HT∶PCBM/TiO2 nanotube based solar cell with a TiO2 binding layer between the nanotubular film and the ITO sub-strate.The two step method shows a great potential in the commercial application of the polymer solar cells.
