Title:
THERMOELECTRIC CONVERSION MATERIAL, THERMOELECTRIC CONVERSION ELEMENT, THERMOELECTRIC CONVERSION MODULE, AND LIGHT SENSOR
Document Type and Number:
WIPO Patent Application WO/2019/180999
Kind Code:
A1
Abstract:
A thermoelectric conversion material including: a base material being a semiconductor comprising a base material element; a first additive element being a different element from the base material element, having a spare d orbit or f orbit positioned on the inside of the outermost shell thereof, and forming a first additional level inside a forbidden band of the base material; and a second additive element that is different from both the base material element and the first additive element and forming a second additional level inside the forbidden band of the base material. The difference between the number of electrons in the outermost shell of the second additive element and the number of electrons in the outermost shell of at least one base material element is 1.
