摘要： The object of the present invention is to provide a thermal power generation battery with excellent battery characteristics.
The above problem can be solved by a thermal power generation element that does not require a temperature gradient, wherein a first part comprising a semiconductor which produce thermally excited electron and hole, a second part comprising an electrolyte in which an charge transport ion pair can be moved therein, and a third part comprising a substance that is an electrode, are in contact with each other in this order, and wherein a valance band potential of the semiconductor of the first part is positive with respect to a redox potential of a charge transport ion pair; and an ion which is more susceptible to oxidation among the two ions is oxidized at an interface between the first part and the second part; and an ion which is more susceptible to reduction among the two ions is reduced at an interface between the third part and the second part; and wherein the thermal power generation element satisfies the following formula (I): L / IDT = 1 − 20 wherein L is a "shortest distance between the first part and the third part", and IDT is "ion diffusion thickness."
