SAM Thermoelectric Technologies

SAM Thermoelectric Technologies owns a patented concept to convert heat efficiently into electricity.

SAM has licensed its technology to O-Flexx Technologies GmbH.

Technological overview

This thermoelectric process involves large area pn-junctions quite similar to solar cells, which can be made from almost all semiconducting materials and production processes.
Using pn-junctions makes it possible to produce more electric current than with conventional thermocouples, even at lower temperatures. The efficiency of the conversion process is improved considerably as shown below.


Depending on the properties of the used material a wide range of temperatures can be used to produce electricity, from body heat to extremly high temperatures of more than 1000°C. The technology of SAM is especially useful to re-use waste heat of industrial processes and the exhaust heat of internal combustion engines.
