    摘要： A thermoelectric module including at least a first and a second thermoelectric element comprising a thermoelectric semiconductor; an electrode connecting the first and second thermoelectric elements; and at least a first and a second joining layer, the first joining layer positioned between the first thermoelectric element and the electrode, and the second joining layer positioned between the second thermoelectric element and the electrode; and at least a first and a second barrier layer including an alloy including Cu, Mo and Ti, the first barrier layer positioned between the first thermoelectric element and the first joining layer, and the second barrier layer positioned between the second thermoelectric element and the second joining layer. The module prevents heat diffusion of the material of the joining layer, preventing the oxidation and deformation of the thermoelectric element under high temperature environment, and exhibiting improved operational stability due to excellent adhesion to a thermoelectric element.
