ABSTRACT
Accurate many-body perturbation theory-based calculations were used to study the electronic and excitonic properties of lead-free quaternary antiperovskite Ca6N2AsSb; large quasiparticle band gap renormalization, strong optical absorption, and low exciton binding energy, as well as high efficiency of >32% with a thickness of 500 nm were predicted.
