Outline of Final Research Achievements

The renewable energy solar shell is indispensable now that the energy problem is serious. In this research, for the purpose of improving the efficiency of solar cells, we fabricated semiconductors with intermediate bands and evaluated their properties. In the semiconductor to which oxygen is added to ZnTe, an intermediate band is formed. Optimization of oxygen composition is necessary to achieve high efficiency. In theory, the oxygen composition was calculated to be 2%, whereas the oxygen composition that could be produced so far was 1%. Sulfur (S) was added to increase the oxygen composition.
