Maximum performance in self-compatible thermoelectric elements

Abstract

Within the framework of a new optimization strategy based on self-compatible thermoelectric elements, the ability to reach maximum performance is discussed. For the efficiency of a thermogenerator and the coefficient of performance of a Peltier cooler, the constraint z T = k_o = const. turned out to provide a suitable criterion for judging maximum performance. In this paper k_o is calculated as an average of the temperature dependent figure of merit z T
