Electronic band structures, the total density of state, the partial density of state, and optical properties were investigated using first principle method for SrPbO3 via Generalized Gradient Approximation (GGA) based on the Perdew–Burke–Ernzerhof (PBE0). The band gap was recorded at 0.768 eV. The electron hopping happens between similar electronic localized states within the section of the quality edge with electron quality of that's ~〖10〗^(-2) m^2 V^(-1) s^(-1) That's thermally activated. The density of state and partial density of state was simulated for evaluating the nature of 5s, 4d for Sr, 6s, 4f, 5d, 6p for Pb and 2s, 2p for O atom for SrPbO3 orbital travelling with the maximum valance band (MVB) to the minimum conduction band (MCB) to explain the transition of electrons due to hybridization. The optical properties, for instance, absorption, reflection, refractive index, conductivity, dielectric function, and loss function, were calculated, which can account for the superior absorption of the visible light. The key point of this research is to determine the activity on electronics structure and optical properties for Fe doped by 6%. From the band gap and optical properties, SrPb0.94Fe0.06O3 can give more conductivity than of SrPbO3, showing as a superconductor.
