中文摘要：

使用简单的水热法在锌片上生长ZnO纳米棒阵列,并用电化学共聚制备了ZnO纳米棒阵列与聚噻吩（Zn/ZnO/PTH）复合膜。通过X射线衍射（XRD）、扫描电子显微镜（SEM）等手段对ZnO的结构和形貌进行表征,XRD结果表明产物为六方纤锌矿型ZnO。SEM结果表明,在垂直锌片方向生长了包括纳米棒、纳米片、纳米线的表面光滑的ZnO纳米阵列,其中以纳米棒为主,其直径为30～100nm,长度〉1μm。用光电流作用谱、光电流-电势图研究了Zn/ZnO/PTH电极的光电转换性质。结果表明,PTH修饰ZnO/Zn电极可使光电流产生波长发生明显红移,使其光电转换效率提高了4倍,填充因子FF=33%,光电转换效率η=1.25%。

英文摘要：

The ZnO nanorod arrays were synthesized on zinc foil by using the hydrothermal method.The ZnO nanorod arrays were characterized by X-ray diffraction（XRD）,scanning electron microscope（SEM）.X-ray diffraction（XRD） analysis of the product layer on the Zn substrate suggests a hexagonal ZnO phase（JCPDS： 36-1451）.SEM shows the whole surface of the Zn foil is completely covered with the nanorods.More important,the nanorods grow oriented perpendicular to the Zn substrate surface.The photo voltaic conversion properties of Zn/ZnO nanorod arrays film and Zn/ZnO nanorod arrays/polythiophene（PTH） film were studied by using the photocurrent action spectra.The photovoltaic conversion efficiency of Zn/ZnO nanorod arrays/polythiophene（PTH） film could be improved with 4 times.
