Abstract

The ultrahigh optical absorption coefficient of AgBiS₂ has been achieved by atomic periodic engineering of AgS₆ and BiS₆ octahedrons. Furthermore, strong dielectric constant modulation and direct band gap of tetra-I4₁/amd AgBiS₂ are obtained, which enable a high spectroscopic limited maximum efficiency of 29.7% at an ultrathin thickness of 100 nm.
