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.

Technology-comparison

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.
