Maximum performance in self-compatible thermoelectric elements

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 constraintz T=ko= const. turned out to provide a suitable criterion for judging maximum performance. In this paperkois calculated as an average of the temperature dependent figure of meritz T.
