(a) Seebeck coefficient, electrical conductivity and (b) power factor as a function of carrier density at different overlap parameter values. We note than the highest power factor is obtained at a carrier density of 2 × 1020 cm−3, corresponding to 20% of sites being occupied. (c) Seebeck coefficient vs. Electrical conductivity showing the increase in electrical conductivity and Seebeck coefficient with stronger electronic orbital overlap. (d) Comparison of the conductivity vs. Seebeck plot for hopping rates computed using Miller-Abrahams and Marcus rate equations.
