Abstract
The conventional thermoelectric figure of merit and power factor is not sufficient as a measure of thin film quality of thermoelectric materials, where the power conversion efficiency depends on the film dimensions. By considering the film size, the effective thermoelectric figure of merit and effective Seebeck coefficient is introduced to guarantee that the maximum energy conversion efficiency increases as the effective thermoelectric figure of merit increases. Similarly, the effective power factor is defined. By introducing typical material properties for Bi2Te3 and PEDOT, we study the thickness dependence of the effective figure of merit and the effective power factor.
