Title:
THERMOELECTRIC CONVERSION ELEMENT, THERMOELECTRIC CONVERSION MODULE, AND METHOD FOR PRODUCING THERMOELECTRIC CONVERSION ELEMENT
Document Type and Number:
WIPO Patent Application WO/2023/276266
Kind Code:
A1
Abstract:
The thermoelectric conversion element comprises: a first electrode; a photoelectric conversion material part that converts heat to electricity; an intermediate layer disposed on the thermoelectric conversion material part; an electroconductive bonding material that is disposed between the intermediate layer and the first electrode and that bonds the first electrode to the intermediate layer; and a second electrode that connects to the thermoelectric conversion material part. The intermediate layer comprises: a dopant-containing first layer disposed on the thermoelectric conversion material part; and a second layer that is disposed on the first layer and inhibits element diffusion. The interfacial resistivity of the intermediate layer is 0.0001 mΩcm2 to 0.5 mΩcm2.
