  • Thermoelectric element and thermoelectric converter including at least one such element
    Patent number: 10658561
    Abstract: A thermoelectric element, particularly for a thermoelectric converter, includes an assembly of constituent layers comprising a central layer made of p- or n-type thermoelectric material, then, in an assembly direction, and on each side of said central layer, an intermediate layer forming a diffusion barrier followed by a buffer layer made of composite metal material. The buffer layers are intended to be secured to metal electrodes, characterized in that the cumulative thickness of the two buffer layers is greater than or equal to 50% of the thickness of the central layer, and preferably greater than or equal to 100% of the thickness of the central layer and very preferably greater than or equal to 200% of the thickness of the central layer, and in that the constituent material of the buffer layers is an alloy of two metals chosen from the family: TixAg1-x, VxFe1-x, VxAg1-x, TixFe1-x, where 0<x<1.
