Research Abstract

Sun shine is one of the most important renewable energies. We have grown semiconductors which has an intermediate band gap to increase the efficiency of solar cell. We have investigated that the ZnTeO alloy which consists of ZnTe and O has intermediate band. To utilize semiconductor as solar cell, pn junction is needed. However, it is difficult to make n-type ZnTe because of self-compensation. We have made n-type ZnTeO by Al-diffusion.
