Thermoelectric Oxide Modules and Their Characterization

Research and commercialization of thermoelectric modules based on oxides are still in their infancy. On an international level, Japan plays a key role in the development of oxide modules, and capability of oxide-based TOMs could be demonstrated [107-lllj. In recent years, work was also published by groups in Europe [112-115]. 

Based on this concept, recently Populoh et al. [16] designed and constructed a testing device for TEGs operating at high temperatures up to 1250K. In this work an AIN block was used for the determination of the heat flux Q . 

The maximum AT was 785 K and reached at Phot = 1098 K and rcoid = 313K resulting in a power output of 154mW and an open-circuit voltage of koc = 0.47 V. The maximum power density was 240mW/cm and the efficiency
