THERMOELECTRIC CONVERSION ELEMENT

摘要

PROBLEM TO BE SOLVED: To provide a thermoelectric conversion element having a superior performance index. SOLUTION: The thermoelectric conversion element includes at least two types of clathrate compounds. It is desirable that a clathrate compound whose electron mobility is 100 to 5,000cm2/Vs and a clathrate compound whose electron concentration is 1.0×1020to 1.0×1022/cm3are used as n-type thermoelectric conversion elements. It is desirable that a clathrate compound whose Hall mobility is 100 to 2,000cm2/Vs, and a clathrate compound whose Hall concentration is 1.0×1020to 1.0×1022/cm3is used as p-type thermoelectric conversion elements.
