Abstract The optimal performance of a semiconductor thermoelectric generator iapanalysed by using the theory of finite-time thermodynamics.The power output andefficiency of the generator under the influence of three main irreversible effects ofheat conduction, heat leak, and Joule heat are derived. From them, the relationsamong the performance of the generator, the parameters of the semiconductor mater ials, the configurations of the semiconductor elements, as well as the load resistanceare discussed.
