Nanofiber-based thermoelectric generator module, method for manufacturing the same, and electrospinning apparatus for manufacturing nanofibers therefore

A nanofiber-based thermoelectric generator module comprising:

• a plurality of module unit bodies stackingly formed on each other in a stacking direction and longitudinally disposed between a hot source and a cold source, the hot source and the cold source being two different heat sources from each other,
• wherein each respective module unit body of the module unit bodies comprises:
• a first nanofiber mesh including a first nanofiber including an n-type semiconductor or a p-type semiconductor;
• a second nanofiber mesh including a second nanofiber including a semiconductor of a type that is the n-type or the p-type, and different from the type, that is the n-type or the p-type, of the semiconductor forming the first nanofiber;
• an insulator layer interposed between the first nanofiber mesh and the second nanofiber mesh;
• a first electrode configured to interconnect ends of the first nanofiber mesh and the second nanofiber mesh;
• and
• a second electrode connected at one end thereof to the second nanofiber mesh and connected at another end thereof to the first nanofiber mesh of another adjoining one of the stacked module unit bodies,
• wherein
• a mesh overlap region is formed, where, taken from a plan view in the stacking direction, the first nanofiber mesh of the respective module unit body overlaps with the second nanofiber mesh,
• a mesh non-overlap region is formed, where, taken from a plan view in the stacking direction, the first nanofiber mesh of the respective module unit body is placed without overlapping with the second nanofiber mesh or the second nanofiber mesh of the respective module unit body is placed without overlapping with the first nanofiber mesh of said another adjoining one of the stacked module unit bodies, and
• at least one of
• the first electrode is disposed at the mesh non-overlap region to be directly connected to and to be stacked in the stacking direction directly on a portion of the first nanofiber mesh that is disposed in the mesh non-overlap region, and
• the second electrode is disposed at the mesh non-overlap region to be directly connected to and to be stacked in the stacking direction directly on a portion of the second nanofiber mesh that is disposed in the mesh non-overlap region.
