因氧化亚铜(Cu2 O)、氧化锌(ZnO)能级和晶格匹配较好，近年来较多的研究者将两者复合制备异质结太阳能电池。异质结的形成可提高光生电子-空穴对的分离效率，同时拓展复合结构的光响应范围，从而有效提高太阳能电池性能。介绍了3类主流的 ZnO/Cu2 O 异质结结构，分别阐述主要的进展，综述了异质结结构中 Cu2 O、ZnO的制备方法以及制备条件对电池效率的影响，讨论了电池性能的改进措施，并对 ZnO/Cu2 O 异质结太阳能电池未来的发展前景进行展望。
Much attention recently has been paid on p-n heterojunction solar cells fabricated with cuprous oxide combined with zinc oxide owing to the advantage of favorable alignment of conductive band edges and lattice matching. The formation of heterojunctions can enhance the seperation of photoinduced electrons and holes,as well as the absor-bance of the light.This review compiles the main milestones reached during the last decades in the development of ZnO/Cu2 O heterojunction solar cells comprehensively.Different junction structures of these cells as planar and ZnO nanoarray based ones related to deposition sequences and synthesis methods are introduced separately,while photovol-taic property influence factors as well as improving methods are discussed.Considering the accomplishments achieved in a relatively short period of time,it can be said that this kind of solar cell can be promisingly applied in clean energy exploitation in the future,in spite of improvement of cell performance still in need.
