Why is it important?
Thermoelectrics provide technology to convert waste heat to electricity and save energy. For high temperature industrial processes, existing thermoelectrics are not stable enough in air, and novel oxide thermoelectrics need be developed. While materials and individual legs can be tested, there has been a lack of a way to test modules at high temperatures. The stability of materials and especially their interfaces and interconnects under operating conditions is critical. The integration of the test setup into a commercially available sample holder system enables development and standardization of a unit available to scientists working with thermoelectrics, especially oxide thermoelectrics for high temperature and operation in air, where standard or commercial products for testing modules have not existed till now.
