摘要

电化学沉积是一种绿色高效的材料制备方法。本实验使用电化学沉积法分别制备了单晶的氧化锌(ZnO)纳米棒阵列和p型的氧化亚铜(Cu

O)薄膜

并对样品进行了扫描电镜、X光衍射、外量子效率和光电性能测试等一系列的表征和测试。试验结果表明

通过改变反应溶液中的ZnCl

浓度可以来调控ZnO纳米棒的直径。光电性能测量显示在Cu

O/ZnO间形成了p-n异质结。量子效率的测试证明该异质结可有效地促进载流子的分离和传送

从而提高太阳能电池的转化效率。

Abstract

Single-crystal n-type zinc oxide (ZnO) nanorod arrays

p-type cuprous oxide (Cu

O) film

and Cu

O/ZnO heterostructures were fabricated by electrochemical deposition. The diameter of ZnO nanorods can be controlled by changing the ZnCl

concentration as it increases with the concentration of ZnCl

. Electrical measurements demonstrate a p-n junction forms between Cu

O film and ZnO nanorod arrays. External quantum efficiency of the p-n junction is higher than that of ZnO nanorod arrays and Cu

O film

which indicates that the formation of a p-n junction between Cu

O film and ZnO nanorod arrays can efficiently facilitate the separation and transport of charge carriers for applications in solar cells.
