Abstract: A material descriptor generation method includes: acquiring a composition formula of a material; generating, from the composition formula, a formula expressing a base material and a dopant list including one or more formulas expressing one or more dopants used to dope the base material; computing descriptors needed to predict a predetermined property value of the material, the descriptors corresponding to the dopant list and the formula expressing the base material; and outputting a material descriptor consolidating the descriptors. The material descriptor is input into a predictive model that predicts the predetermined property value of the material.

Abstract: A thermoelectric conversion material of the present disclosure is a p-type thermoelectric conversion material which includes an alloy containing Mg and Bi as a main phase and which contains carbon. The thermoelectric conversion material includes, for example, a Mg3(Sb,Bi)2-based alloy as the main phase. An atomic percentage of Bi included in the main phase is greater than or equal to an atomic percentage of Sb included in the main phase. The thermoelectric conversion material satisfies, for example, 0.01 at %≤CC≤1.2 at %, where CC represents a content ratio of carbon in the thermoelectric conversion material.

Abstract: A thermoelectric conversion device includes a reflecting member that has an opening portion through which radiant heat from a heat source passes, and a concave reflecting surface that reflects the radiant heat that has passed through the opening portion; a thermoelectric conversion member that converts heat into electric power; and a heat collector that is disposed between the reflecting member and the thermoelectric conversion member, and that is disposed such that at least a part of the heat collector faces the reflecting surface of the reflecting member. The heat collector includes a heat-collecting region that absorbs the radiant heat reflected by the reflecting surface of the reflecting member, and a heat transfer region that transfers the radiant heat absorbed by the heat-collecting region to the thermoelectric conversion member.

Abstract: A thermoelectric conversion unit includes: a first fluid passage that has a first main surface and a second main surface and through which a first fluid flows; a second fluid passage through which a second fluid having a higher temperature than the first fluid flows; a pair of thermoelectric modules including a first thermoelectric module and a second thermoelectric module; and a pair of magnetic body portions disposed inside of or on a surface of the first fluid passage along a predetermined direction from the first main surface toward the second main surface. Each of the first and second thermoelectric modules generates an electromotive force based on a temperature difference between the first fluid and the second fluid. Magnetic bodies of the pair of magnetic body portions are disposed so that the same magnetic poles thereof face each other, and generate magnetic forces that repel each other.
