Abstract

Solar renewable energy is the need today to combat the high decline rate of storage of fossil fuels. Paper presents electronic and optical analysis of KGeBr₃by employing Density Functional Theory using mBJ potential in FP-LAPW environment using WIEN2K package. Computed energy gap of KGeBr₃ found 0.54 eV in the reciprocal lattice space. Absorption coefficient analysis manifests that KGeBr₃ material absorbs light in the visible spectrum and Si absorbs light in the ultraviolet spectrum. Hence, it is predicted that perovskite KGeBr₃material will have strong potential to work as a high efficient solar cell in tandem perovskite-Si configuration.
