Title:
COMPOSITE THERMOELECTRIC CONVERSION MATERIAL, THERMOELECTRIC CONVERSION MATERIAL PASTE USING SAME, AND THEMOELECTRIC CONVERSION MODULE USING SAME
Document Type and Number:
WIPO Patent Application WO/2013/061739
Kind Code:
A1
Abstract:
　Provided are: a composite thermoelectric conversion material with which it is possible to produce high-performance thermoelectric conversion elements using a low-cost process; a thermoelectric conversion material paste using the composite thermoelectric conversion material; and a low-cost, high-efficiency thermoelectric conversion module.　The composite thermoelectric conversion material according to the present invention is obtained by forming a composite of a semiconductor thermoelectric conversion material and a binder, and is characterized in that the binder is a semiconductor glass having the same polarity as the semiconductor thermoelectric conversion material, and in that the semiconductor glass is a lead-free glass which has a softening point of 480°C or lower and includes vanadium oxide when the components are expressed as oxides.
