采用简单的两步电沉积方法制备了n型ZnO纳米线阵列嵌入p型Cu2O薄膜的纳米柱异质结。研究了纳米柱径向结阵列在太阳能电池中的结构、光学和电学性能，通过增加结面积和改善电荷载流子的收集，实验观察到与在相似条件下制备的平面薄膜结相比，Cu2O/ZnO纳米柱结的效率有所提高。这很容易适应其他化学体系。是一种很有前途的低成本纳米柱太阳能电池的大规模制造技术。
Nanopillar heterojunctions composed of n-type ZnO nanowire arrays embedded in p-type Cu2O thin films were fabricated by using a simple two-step electrodeposition method. Structural, optical, and electrical properties of the nanopillar junctions were investigated Nanopillar radial junction arrays have the potential for improved performance in solar cells clue to increased junction area and improved charge carrier collection Improved efficiency in the Cu2O/ZnO nanopillar junctions was experimentally observed compared to planar thin film Junctions prepared under similar conditions This study demonstrates that electrodeposition, which is easily adapted to other chemical systems. is a promising technique for large-scale fabrication of low-cost nanopillar solar cells.
