Abstract：High-efficient conversion of solar energy into electricity or fuels plays a vital role in reducing the pollution and averting a global energy crisis. In recent years, due to the rapid developments of the computer technologies and the first-principle calculation method based on Density Function Theory (DFT), computational design of the optical, electrical, and transport properties of energy materials have become the most practical way for improving their performances. In this presentation, based on the first-principle simulations, I will present our recent works on understanding and design of group III-V and II-VI semiconductors for energy applications. The examples include GaAs and its alloys, III-V and II-VI superlattices, and oxides for photovoltaic (PV) and photoelectrochemical (PEC) water splitting applications.
