WIPO Patent Application WO/2023/053962
Kind Code:
A1
Abstract:
Provided are a thermoelectric power generation device, as well as a thermoelectric power generation device component and a manufacturing method therefor, with which it is possible to improve power generation efficiency. A thin film thermoelectric power generation device 10 comprises: a flexible substrate 13 that has a strip-shaped first strip-shaped section 11 and a strip-shaped second strip-shaped section 12, both ends thereof being respectively connected in the width direction to both ends of the first strip-shaped section 11, and is deformed in a direction in which a center section in the direction of extension of one of the first strip-shaped section 11 and the second strip-shaped section 12 is separated away from a heat source Hs, and such that one surface of the other is in contact with the heat source Hs; and a thermoelectric element section 19 that has a thin film-shaped p-type first thermoelectric element 17 splitting from one end region 17a, which is on the surface on the opposite side from the heat source Hs and on the side of one end where the first strip-shaped section 11 and the second strip-shaped section 12 are connected, and extending toward the respective centers of the first strip-shaped section 11 and the second strip-shaped section 12, and a thin film-shaped n-type second thermoelectric element 18 splitting from another end region 18a, which is on the surface on the opposite side from the heat source Hs and on the side of the other end where the first strip-shaped section 11 and the second strip-shaped section 12 are connected, and extending toward the respective centers of the first strip-shaped section 11 and the second strip-shaped section 12, one end of the first thermoelectric element 17 and one end of the second thermoelectric element 18 being connected, and said ends being on the surface of the second strip-shaped section 12.
