Abstract
The invention provides a thermoelectric conversion element and a method of manufacturing same. The thermoelectric conversion element including a thermoelectric conversion member formed of a skutterudite-type material containing an element L (indicating one or more elements selected from a group including In, Yb, Eu, Ce, La, Nd, Ga and Sr), an element M (indicating one or more elements selected from a group including Co, Rh, Ir, Fe, Ni, Pt, Pd, Ru and Os), and an element Pn (indicating one or more elements selected from a group including Sb, As, P, Te, Sn, Bi, Ge, Se and Si), an insulator covering the thermoelectric conversion member and a metal layer positioned between the thermoelectric conversion member and the insulator as well as containing the element L. The element has high reliability.
Description
technical field [0001] The present invention relates to a thermoelectric conversion element and a manufacturing method thereof. Background technique [0002] A thermoelectric conversion material and a thermoelectric conversion module using the same are used for cooling or power generation as a device for converting heat and electric power. For example, when a direct current is passed through the thermoelectric conversion material, heat transfers from one surface to the other, thereby generating a heat-absorbing surface and a heat-generating surface. This phenomenon is called the Peltier effect, and by modularizing a thermoelectric conversion material and bringing it into contact with an object whose heat-absorbing surface is to be cooled, it is possible to cool an object without installing a movable part. On the other hand, when a temperature difference is applied across the thermoelectric conversion material, an electromotive force proportional to it is generated. This ph...
