Abstract
A semiconductor element for a thermoelectric module has opposite ends and is made of an n-doped or p-doped semiconductor material and at least one foreign material. The foreign material is mixed with the semiconductor material and forms a fraction of 25 to 75 vol % of the semiconductor element. A method for producing a tubular thermoelectric module includes providing an inner tube having an axis, an inner circumferential surface and a first outer circumferential surface, alternately placing n-doped and p-doped semiconductor elements in direction of the axis, placing second electrical conducting elements radially outwardly of the semiconductor elements so that pairs of adjacent semiconductor elements are electrically conductively connected to each other at the outside to then form a second outer circumferential surface, and compressing the thermoelectric module. A motor vehicle having a thermoelectric module is also provided.
