Influence of phonon anharmonicity on Raman spectra of Cu2ZnSn(S,Se)4 polycrystalline thin films through computational study

Abstract Cu2ZnSn(S,Se)4 (CZT(S,Se)) thin films exhibit the characteristics necessary to be effective absorbers in solar cells. In this report, the room temperature experimental Raman scattering spectra, recorded at different excitation wavelengths, are systematically analyzed theoretically using the...
