Embodiment 1

[0053] (Structure of thermoelectric conversion element)

[0054] Below, refer to figure 1 The structure of the thermoelectric conversion element of Example 1 of the present invention will be described. figure 1 It is a cross-sectional view schematically showing the thermoelectric conversion element of Example 1. FIG. in addition, figure 1 is a cross-sectional view along the extending direction of the thermoelectric conversion member constituting the thermoelectric conversion element.

[0055] Such as figure 1As shown, the thermoelectric conversion element 1 of Example 1 has a first thermoelectric conversion component 2 made of N-type semiconductor material, a second thermoelectric conversion component 3 made of N-type semiconductor material, and the first thermoelectric conversion component 2 and the second thermoelectric Electrodes 4a, 4b joined to both ends of the conversion member 3 . In this embodiment, the first thermoelectric conversion component 2 and the secon...

Embodiment 2

[0076] In the first embodiment described above, the second end portion 2b of the first thermoelectric conversion element 2 and the second end portion 3b of the second thermoelectric conversion element 3 are brought into contact with the bottom surface of the holding part 11 of the manufacturing apparatus 10, whereby , align the second ends 2b, 3b on the same plane, but it is also possible to use Figure 7 The method shown aligns the second ends 2b, 3b on the same plane. Figure 7 With figure 1 A schematic cross-sectional view in the manufacturing process of the thermoelectric conversion element 1 is shown similarly. In addition, except for the process of holding the first thermoelectric conversion member 2 and the second thermoelectric conversion member 3 by the manufacturing apparatus, it is the same as the above-mentioned Example 1, and therefore descriptions other than the holding process are omitted.

[0077] Such as Figure 7 As shown, the holding part 21 of the manuf...

Embodiment 3

[0083] The thermoelectric conversion element of the present invention is not limited to the thermoelectric conversion element 1 of Embodiment 1 and Embodiment 2 described above, and may be formed by covering the ends of the thermoelectric conversion member with all the electrodes positioned at both ends of the thermoelectric conversion member. That is, all the electrodes may be formed of metal powder. Hereinafter, the thermoelectric conversion element 101 having such a structure will be referred to as Embodiment 3, referring to Figure 8 ~ Figure 14 Its structure and manufacturing method will be described.

Abstract

A method for manufacturing a thermoelectric conversion element includes: a holding step of holding at least one thermoelectric conversion member (2, 3) while at least one end of the thermoelectric conversion member is exposed; a coating step of coating the exposed end of the thermoelectric conversion member with metal powder (13); and an electrode forming step of forming an electrode (4a) at the end of the thermoelectric conversion member by sintering the metal powder.

Description

technical field [0001] The present invention relates to a method for manufacturing a thermoelectric conversion element and a thermoelectric conversion element manufactured by the manufacturing method, and particularly relates to a thermoelectric conversion element with stable thermoelectric characteristics and a method for manufacturing the same. Background technique [0002] The thermoelectric conversion module converts thermal energy into electrical energy through the Seebeck effect. By utilizing such energy conversion properties, it is possible to convert waste heat discharged from industries, domestic processes, and mobile bodies into effective electric power. Therefore, this thermoelectric conversion element has attracted attention as an energy-saving technology that takes environmental issues into consideration. [0003] Such a thermoelectric conversion element is generally constituted by joining a plurality of thermoelectric conversion elements (p-type semiconductor a...
