Title:
METHOD FOR MANUFACTURING THERMOELECTRIC CONVERSION MODULE, THERMOELECTRIC CONVERSION MODULE, AND BINDER FOR THERMOELECTRIC CONVERSION MODULE
Document Type and Number:
WIPO Patent Application WO/2019/082932
Kind Code:
A1
Abstract:
The present invention provides a method for manufacturing a thermoelectric conversion module having: a thermoelectric semiconductor portion in which a plurality of p-type semiconductors and n-type semiconductors are alternately arranged; a high-temperature-side electrode bonded to high-temperature heat source-side bonding surfaces of the p-type semiconductors and the n-type semiconductors; and a low-temperature-side electrode bonded to low-temperature heat source-side bonding surfaces of the p-type semiconductors and the n-type semiconductors, wherein the high-temperature-side electrode and the low-temperature-side electrode electrically connect in series the p-type semiconductors and the n-type semiconductors that are adjacent to each other. The method comprises a bonding step for bonding at least one among the high-temperature-side electrode and the low-temperature-side electrode with the p type semiconductors and the n type semiconductors by sintering a bonding layer which is disposed therebetween and contains metal particles, wherein the bonding layer is formed by a binder containing copper particles as the metal particles.
