Abstract

Oxide module studies for thermoelectric energy harvesting at a high temperature were performed in this study. Considering the degradation of the electrode properties by oxidation at normal operating temperatures in air, a silver electrode (Ag) was selected for use in this study. Two types of contact problems causing a severe loss in electrical power generation were investigated: potential barriers at the interfaces, and inter-diffusion problems. Also, two types of thermoelectric modules were fabricated using Ag electrodes: a module with n-type CaMnO3 and p-type Ca3Co4O9 oxides and another module with n-type (ZnO)7In2O3 and p-type Ca3Co4O9 oxides. The measured power density values were compared with the values calculated from the materials properties.
