Improved thermoelectric assemblies are disclosed, wherein layers of heterostructure thermoelectric materials or thin layers of thermoelectric material form thermoelectric elements. The layers are bound together with agents that improve structural strengths, allow electrical current to pass in a preferred direction, and minimize or reduce adverse affects, such a shear stresses, that might occur to the thermoelectric properties and materials of the assembly by their inclusion.
