Sikander Azam, Wilayat khan, Saleem Ayaz Khan, A. H. Reshak

The thermoelectric properties of Cu2ZnSnS4 and Cu2ZnSnSe4 are calculated by means of the semi-classical Boltzmann transport theory. The average values of electrical conductivity, thermal conductivity and Seebeck coefficient with two constant temperatures verses chemical potential are reported and discussed in detail. The Seebeck coefficient value recommends that both compounds are good for thermoelectric applications. We also investigated the electrical conductivity, thermal conductivity, Seebeck coefficient, power factor and the resistivity verses variable temperature. In which the maximum power factors are evaluated, suggesting that the compounds have good thermoelectric properties
