Inspired by the high efficiency of mixed halide perovskite CH3NH3PbI3-xClx due to the long diffusion and superior optical property, we pay our attention to the mixed halide germanium perovskite. In this paper, we present a detail theoretical investigation of geometric and electronic structure of mix...
