COMPOSITION FOR FORMING THERMOELECTRIC CONVERSION LAYER, THERMOELECTRIC CONVERSION ELEMENT, AND THERMOELECTRIC POWER GENERATING COMPONENT

摘要

Provided are a composition for forming a thermoelectric conversion layer, the composition having excellent thermoelectric characteristics; a thermoelectric conversion element, in which the composition is used to form a thermoelectric conversion layer; and a thermoelectric power generating component. The composition for forming a thermoelectric conversion layer includes inorganic particles having an average particle size of 1.0 μm or less; a carrier transport material which satisfies at least one of the condition that the mobility is 0.001 cm²/Vs or more and the condition that the carrier density is 1×10¹⁰ cm⁻³ to 1×10²¹ cm⁻³ when the band gap of the inorganic particles is 1.5 eV or less; and a material for a thermal excitation source which is an organic material satisfying the condition that the band gap is 1.5 eV or less when the band gap of the inorganic particles is more than 1.5 eV.
