Title:
THERMOELECTRIC MATERIAL ELEMENT, POWER GENERATOR, LIGHT SENSOR, AND METHOD FOR MANUFACTURING THERMOELECTRIC MATERIAL ELEMENT
Document Type and Number:
WIPO Patent Application WO/2019/171915
Kind Code:
A1
Abstract:
A thermoelectric material element comprising a thermoelectric material part made from a thermoelectric material that includes a first crystal phase and a second crystal phase different from the first crystal phase during operation, a first electrode arranged in contact with the thermoelectric material part, and a second electrode arranged in contact with the thermoelectric material part and apart from the first electrode. The thermoelectric material part includes, during operation, a first temperature region having a first temperature and a second temperature region having a second temperature lower than the first temperature region. The ratio of the first crystal phase to the second crystal phase is greater in the first temperature region than in the second temperature region.
