| Outline of Final Research Achievements |
The technique for controlling the characteristics and optimization of the structure has been investing to develop the 1.4-eV-CuO-photovoltaic devices with high theoretical conversion efficiency and the preparation process with electrochemical process. The internally stacked CuO/Cu2O bilayer structure has been prepared by electrodeosition of the Cu2O layer followed by heating in air, and both the 2.1-eV-Cu2O and 1.4-eV-CuO layers act as photovoltaic layers, resulting in the expansion of the absorption band.
