  As described above, the thermoelectric conversion module 1 is in the form of a film in which the film-like thermoelectric conversion elements 11 and 13 are formed on the substrate 10, and is formed thin as a whole.

  For the substrate 10, a film made of a resin such as polyethylene or polyimide is used. However, the present invention is not limited to this. For example, glass or the like can be used. However, when a resin film is used, there is an advantage that the flexibility is excellent and the application range is wide.

  The thermoelectric conversion element 11 is an n-type element, and when there is a temperature difference between both ends, a current flows from the low temperature end to the high temperature end. In the present embodiment, ITO (indium tin oxide) is used as the thermoelectric conversion element 11, but is not limited thereto. Known inorganic materials that can be used as n-type elements can be used, and examples thereof include platinum, constantan, alumel, SUS (stainless steel), invar, and indium zinc oxide.

  On the other hand, the thermoelectric conversion element 13 is a p-type element, and when there is a temperature difference between both ends, a current flows from a high temperature end to a low temperature end. In the present embodiment, copper is used as the thermoelectric conversion element 13, but is not limited thereto. Known inorganic materials that can be used as p-type elements can be used, examples of which include silver, gold, iron, and chromel.

  In this embodiment, the high temperature part H and the low temperature part L are made into a substantially rectangular area, and the two high temperature parts H and the low temperature parts L are alternately arranged in parallel at intervals on a plane on the substrate 10. It has established. However, the pattern of the high temperature part H and the low temperature part L is not restricted to this.

  The thermoelectric conversion elements 11 and 13 are arranged in two upper and lower rows, and in each row, the two ends of the plane are arranged in the high temperature portion H and the low temperature portion L, respectively.

  The thermoelectric conversion elements 13 have a stripe shape, and in each row, a plurality of thermoelectric conversion elements 13 are arranged in parallel at intervals in the longitudinal direction of the high temperature portion H (low temperature portion L).

  The thermoelectric conversion elements 11 are arranged so as to connect adjacent thermoelectric conversion elements 13 in each row. That is, the thermoelectric conversion element 11 is disposed so as to connect the end portion on the low temperature portion L side of one thermoelectric conversion element 13 and the end portion on the high temperature portion H side of the other thermoelectric conversion element 13.

  A wiring portion 15 is also provided on the substrate 10. The wiring part 15 can use various conductive materials, for example, can use copper, silver, gold | metal | money, aluminum, etc.

  In the present embodiment, one of the thermoelectric conversion elements 11 (the upper element in the figure) of the thermoelectric conversion elements 11 (the upper and lower two thermoelectric conversion elements 11 at the left end in FIG. 2A) at the end of each row.

The protective layer 17 is formed into a thin film by bonding various known resin films or applying a resin. In addition, illustration of the protective layer 17 is abbreviate | omitted in Fig.2 (a). The same applies to FIG. 6A described later.

(3. Manufacturing method of thermoelectric conversion module 1)
In the present embodiment, when the thermoelectric conversion module 1 is manufactured, the thermoelectric conversion elements 11 and 13 are formed on the base material 10 using photolithography and etching techniques.

  That is, first, as shown in FIG. 3 (a), ITO, which is a material of the thermoelectric conversion element 11, is applied on the base material 10 by sputtering or vapor deposition, and a photosensitive resin is applied thereon as shown in FIG. 3 (b). 31 (resist) is applied. In this embodiment, the photosensitive resin 31 is a positive type, and the photosensitive resin 31 in the part is softened by exposing a part other than the pattern of the thermoelectric conversion element 11.

  By performing the development, as shown in FIG. 3C, the photosensitive resin 31 at that portion is removed, and a pattern of the photosensitive resin 31 corresponding to the pattern of the thermoelectric conversion element 11 is formed. The ITO is exposed at the place where the photosensitive resin 31 is removed.

  Thereafter, when etching with an etchant is performed, the exposed portions of ITO are removed as shown in FIG. When the remaining photosensitive resin 31 is removed by chemical treatment or the like, the pattern of the thermoelectric conversion element 11 made of ITO remains as shown in FIG. The photosensitive resin 31 may be a negative type, and in this case, a portion corresponding to the pattern of the thermoelectric conversion element 11 is exposed during exposure.

  In this embodiment, the pattern of the thermoelectric conversion element 11 is thus formed on the substrate 10 as shown in FIG. Similarly, a pattern of the wiring portion 15 is also formed by photolithography and etching as shown in FIG.

  The thermoelectric conversion element 13 is similarly subjected to photolithography and etching to form a pattern of the thermoelectric conversion element 13 as shown in FIG. FIG. 5B shows a cross section similar to FIG. 2B at this time. Thereafter, when the protective layer 17 is formed by adhesion or application, the thermoelectric conversion module 1 described in FIG. 2 is obtained.

  As described above, according to the present embodiment, the thermoelectric conversion module 1 in which the low temperature part L and the high temperature part H are set on the plane is used, the high temperature part H is disposed in the heat source 100, and the low temperature part L is separated from the heat source 100. By providing the thermoelectric conversion module 1 in the heat source 100 so as to be spaced apart, the thermoelectric conversion module 1 can function as a battery that generates an electromotive force due to a temperature difference. Such an arrangement of the thermoelectric conversion module 1 facilitates the mounting, can take various mounting forms, and has a wider application range than the conventional thermoelectric conversion module described above.

  Moreover, in this embodiment, the low temperature part L can be easily separated from the heat source 100 by making the base material 10 bend.

  Furthermore, the thermoelectric conversion module 1 according to the present embodiment is formed by alternately and repeatedly forming a portion disposed on the heat source 100 and a portion disposed away from the heat source 100 as shown in FIG. The high temperature part H is located in the former, and the low temperature part L is located in the latter. By providing the thermoelectric conversion module 1 in the heat source 100 in this way, it is possible to increase the number of peaks and valleys where the high temperature part H and the low temperature part L are located, and increase the electromotive force. However, the mounting structure 200 of the thermoelectric conversion module 1 is not limited to this.

  In the present embodiment, the high temperature portion H of the thermoelectric conversion module 1 is arranged as a heat source. However, the heat source is not limited to this, and the low temperature of the thermoelectric conversion module 1 is used as a cold heat source such as various cooling facilities. It is also possible to arrange the part L. In this case, by disposing the high temperature portion H away from the cold heat source, the thermoelectric conversion module 1 can function as a battery that generates an electromotive force due to a temperature difference, and the same effect as described above can be obtained.

  Further, the thermoelectric conversion module is not limited to the above. For example, as another example of the thermoelectric conversion module, a thermoelectric conversion module 1 ′ as shown in FIG. 6A can be manufactured by using photolithography and etching techniques as described above. In the thermoelectric conversion module 1 ′, the base material 10 is circular, and concentric high-temperature portions H and low-temperature portions L are defined at the center portion and the outer peripheral portion.

  A plurality of thermoelectric conversion elements 11 and 13 are arranged radially from the center of the substrate 10 toward the outer periphery, and both end portions are located in the high temperature portion H and the low temperature portion L. The thermoelectric conversion elements 11 and 13 are alternately arranged in the circumferential direction of the base material 10 at intervals, and the ends of the adjacent thermoelectric conversion elements 11 and 13 on the high temperature part H side or the low temperature part L side are connected by the wiring part 15. By connecting, a series circuit is formed.

  The thermoelectric conversion module 1 ′ has an electromotive force generated by mounting the high temperature portion H on the bottom surface of the heat source 100 and disposing the low temperature portion L away from the heat source 100 as shown in a mounting structure 200 ′ in FIG. It functions as a battery that generates

  In addition, a series circuit can be formed using only p-type or n-type thermoelectric conversion elements without using the n-type and p-type thermoelectric conversion elements 11 and 13. For example, by arranging the wiring portion 15 instead of the thermoelectric conversion element 11 in FIG. 2A, a series circuit using only the p-type thermoelectric conversion element 13 can be formed.

  Furthermore, n-type and / or p-type thermoelectric conversion elements can be formed by a photolithography technique using a conductive polymer material (organic material) as a material.

  For example, a conductive polymer material such as PEDOT: PSS (polystyrenedioxythiophene (PEDOT) added with polystyrene sulfonic acid (PSS)) is used as a material for a p-type thermoelectric conversion element, and this is a negative type material that is dispersed and contained. After applying the photosensitive resin on the base material, the part corresponding to the pattern of the thermoelectric conversion element is cured by exposure, and the other part is removed by development to make the pattern of the thermoelectric conversion element as the pattern of the photosensitive resin Can be formed.
