Organic-inorganic perovskite compounds, which shows high performance in the thermoelectric properties, have been studied by using first-principles calculation. The electronic state of CH₃NH₃SnI₃ and its variation against the carrier density when A site is substituted by divalent cations were calculated. From the result, it was suggested that the carrier density can be controlled while maintaining the band structure.
