摘　　要：以透明导电玻璃(FTO)为基底,采用电化学沉积法制备了Cu_2O敏化的ZnO纳米棒阵列复合薄膜。利用X射线衍射仪(XRD)、扫描电子显微镜(SEM)、透射电镜(TEM)、高分辨电镜(HRTEM)、电化学工作站研究了不同Cu_2O沉积时间对复合薄膜的晶体结构、形貌、光电性质的影响。结果表明,电化学沉积的Cu_2O纳米晶可以与ZnO纳米棒形成异质结,提高ZnO纳米薄膜的光电转换效率,当Cu_2O的沉积时间为5min时,Cu_2O敏化ZnO纳米棒薄膜的光电转换效率最高。Cu_2O sensitized ZnO nanorod array films were prepared on transparent conductive glass(FTO)by electrochemical deposition method.The microstructure,surface morphologies and photoelectric properties of Cu_2O sensitized ZnO films were characterized by X-ray diffraction(XRD),field emission scanning electron microscopy(SEM),transmission electron microscopy(TEM),high-resolution transmission electron microscopy(HRTEM),X-ray energy spectrum(EDS)and electrochemical workstation(CHI601 C).The results show that electrochemical deposition of Cu_2O nanocrystals can be formed heterojunction with the ZnO nanorods and improve the photoelectric conversion efficiency of ZnO thin films.The photoelectric conversion efficiency of Cu_2O sensitized ZnO nanorod films is the highest when the deposition time of Cu_2O is 5 min.
