摘要：

This article demonstrates a facile method to fabricate a solar cell based on p-Cu2O/n-ZnO heterostructure, which was constructed through n-ZnO layer deposition by radio frequency magnetron sputtering and subsequent p-Cu2O film cover by electrochemical deposition with two electrodes. The applied potential and deposition time of the Cu2O were investigated and it was found to be critical to the morphologies, microstructure, and optical properties of the heterojunction solar cells. The current density-voltage J-V) characteristics of p-Cu2O/n-ZnO heterojunction solar cells were measured and show well-defined rectifying behavior. The results indicate that the crystal orientation and morphologies of the Cu2O play key roles in photovoltaic conversion efficiency of the p-Cu2O/n-ZnO heterojunction solar cell.
