|Title||THERMOELECTRIC POWER GENERATION ELEMENT, THERMOELECTRIC POWER GENERATION MODULE INCLUDING SAME, AND THERMOELECTRIC POWER GENERATION METHOD USING SAME|
|Abstract||The objective of the present invention is to provide a thermoelectric power generation element which does not require a temperature gradient, and a thermoelectric power generation system in which said thermoelectric power generation element is used. The present invention can solve the above problem by means of a thermoelectric power generation element characterized in that: a first layer comprising a thermoelectric power conversion material that generates thermally excited electrons and holes, and a second layer comprising an electrolyte solution or a solid electrolyte in which a pair of charge transport ions can move are laminated; the valence band potential of the thermoelectric power conversion material which generates thermally excited electrons and holes inside the first layer is more positive than the oxidation-reduction potential of the pair of charge transport ions inside the second layer; and the more easily oxidized among the ions undergoes an oxidation reaction at the boundary of the first layer and the second layer.|
|Outline of related art and contending technology||
Conventional, such as a factory or geothermal heat as heat using a thermoelectric generation, thermoelectric power generation using the Seebeck effect has been known (Patent Documents 1 and 2, as well as non-patent document 1) in order to effectively use the thermal energy, which is expected. By the Seebeck effect thermoelectric generator, a temperature gradient in a metal or a semiconductor by use of the voltage when the power generation principle. More specifically, p-type semiconductor and n-type semiconductor is coupled to the thermoelectric conversion element, by applying a temperature gradient, converts thermal energy into electrical energy in the thermoelectric power generation system.
The thermoelectric power generation systems, such as a thermal power plant greenhouse gas is not generated. Also, often in a region of a volcano, can be utilized as heat energy from geothermal, promising power generation method are considered.
