The main goal of this work is to examine the structural, electronic and thermoelectric properties for Cesium Germanium halides CsGeCl3 compound using density functional theory. The structural properties are calculated in terms of lattice parameter (a0), bulk modulus (B) and its pressure derivative which show good agreement with the previous available results. The electronic properties have been analysed from band structure and density of states (DOS) which reveals semiconducting nature with direct band gap at R-point. The thermoelectric behaviour has been explored in terms of electrical conductivity (σ/τ), electronic thermal conductivity (κe/τ), Seebeck coefficient (S) and power factor (S2σ/τ). The higher value of Seebeck coefficient suggest that the compound is n-type semiconductor.
