Abstract:
A thermoelectric power module capable of suppressing diffusion of not only a material of a solder layer but also a material of a solder joint layer into a thermoelectric element, or suppressing oxidation of the thermoelectric element. The thermoelectric power module includes in sequence: a thermoelectric element consisting essentially of a thermoelectric material containing at least two kinds of elements of bismuth (Bi), tellurium (Te), antimony (Sb), and selenium (Se) as principal components; a first diffusion prevention layer consisting essentially of at least one of molybdenum (Mo) and tungsten (W); a second diffusion prevention layer consisting essentially of at least one of cobalt (Co), titanium (Ti), and an alloy or compound containing them as principal components; and a solder joint layer consisting essentially of at least one of nickel (Ni), tin (Sn), and an alloy or compound containing them as principal components.

Claim (Index 6):
A thermoelectric power module comprising:\n a thermoelectric element consisting essentially of a thermoelectric material containing at least two kinds of elements of bismuth (Bi), tellurium (Te), antimony (Sb), and selenium (Se) as principal components; a first diffusion prevention layer directly deposited on a surface of said thermoelectric element and having a thickness within a range from 2.7 \u03bcm to 8.7 \u03bcm, said first diffusion prevention layer containing, as a principal component, molybdenum (Mo) having columnar structure and including a crystal of a body-centered cubic lattice such that {110} plane of said crystal is orientated substantially orthogonal to the surface of said thermoelectric element, said columnar structure mitigating film stress generated due to a difference between linear expansion coefficients of said first diffusion prevention layer and said thermoelectric element; a second diffusion prevention layer directly deposited on at least one surface of said first diffusion prevention layer opposite to said thermoelectric element side and consisting essentially of at least one of cobalt (Co), titanium (Ti), and an alloy or compound containing cobalt (Co) and titanium (Ti) as principal components; and a solder joint layer directly deposited on at least one surface of said second diffusion prevention layer opposite to said first diffusion prevention layer side and consisting essentially of at least one of nickel (Ni), tin (Sn), and an alloy or compound containing nickel (Ni) and tin (Sn) as principal components.
