Research Abstract

ZnO/Cu2O solar cell fabricated by aqueous process is safe, secure, low cost and environment-friendly . In this study, thin films of ZnO and Cu2O were deposited by the electrochemical process. By evaluation and improvement of the nucleation and initial growth of ZnO, dense and continuous thin films are obtained with high reproducibility . Dependence of the lattice constant of Cu2O on the concentrations of oxygen sources, hydroxyl and dissolved oxygen in the electrolytes, were also evaluated. It is known that he lattice constant is influenced by the concentration of Cu vacancy which is an origin of the carrier. The results suggest that the carrier density of Cu2O films can be controlled by changing the concentration of oxygen sources.
