Nonstandard Harman Response for Separate Measurements of the Stages of Multicascade Thermoelectric Modules

Journal of Electronic Materials Aims and scope Submit manuscript

We investigated the Harman response R = f(t) (electric resistance R versus time t) from separate stages of two-stage thermoelectric modules with various numbers of elementary thermocouples in a stage. Some special cases were considered when the thermal flow in stages was either coincident or opposed. It was shown that the Harman response from the first stage of modules, and sometimes from modules in general, can have an unusual appearance because of the thermal influence of the second stage. It was found that, by connecting one-stage modules in pairs “head to head,” one can reduce thermal losses from their working joints during measurements in air. It is shown that this effect can be used to increase the accuracy of Harman figure of merit Z H measurements in air when sampling one-stage modules during mass production.
