Abstract

The ab-initio computations were performed to study the electronic and optoelectronic properties of perovskites using WIEN2k code. The has band gap of 2.29 eV, and the behavior of is metallic. The sub-TDOS of the studied materials revealed that rhodium and oxygen atoms have significant contributions in the valence band and conduction band formation of both materials. The silver cation is responsible for the reasonable peaks appearing at the Fermi level of which demonstrated the conducting nature of The dielectric functions, optical conductivity, energy loss function, absorption coefficient, refractive index, extinction coefficient, and reflectivity are computed for these materials to understand the optical behavior of the studied materials. The analysis of optical properties ensure the is a promising material for optoelectronics while has metallic nature.
