Title:
熱電変換材料、およびそれを用いた熱電変換素子、熱電発電モジュール及びペルチェ冷却器
Document Type and Number:
Japanese Patent JP7366393
Kind Code:
B2
Abstract:
To provide a thermoelectric conversion material of no tellurium (Te) content or a decreased tellurium (Te) content and a decreased selenium (Se) content, having a stable and high dimensionless thermoelectric performance index at 373K or lower, and to provide a thermoelectric conversion element, a thermoelectric power generation module, and a Peltier cooler including the same.SOLUTION: A thermoelectric conversion material has a base material containing Ag2Se and at least one element (M) selected from a group consisting of sulfur (S) and tellurium (Te) added to the base material. A ratio x of the number of atoms of M to the number of atoms of selenium (Se) in the base material is more than 0 and 0.06 or less.SELECTED DRAWING: Figure 8
