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 BACKGROUND ART
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.
