Abstract
A module having a plurality of thermoelectric elements electrically connected in series, each being made of at least one n-layer and at least one p-layer made of thermoelectric material with a pn-transition implemented along a boundary layer. A temperature gradient parallel to the boundary layer between a hot and a cold side of each thermoelectric element can be applied or detected. Resistances of the electrical contacts of the individual thermoelectric elements are reduced and the thermal connection to a heat sink or heat source is improved for generating a temperature gradient along the boundary layer. The substrate and the thermoelectric elements are produced in separate processes, and the thermoelectric elements are adhered to previously structured, thermally and electrically conductive regions of the substrate using different adhesives for the cold and hot side of each thermoelectric element.
