Low Energy Thermoelectric Generators

Abstract

The paper describes the possibilities of energy harvesting using thermoelectric generators. It is shown that organic semiconductors enable a large variability of properties and some of their properties may be better than by inorganic semiconductor materials. Nevertheless they suffer from poor electrical conductivity. Because the voltage of one junction is quite low even in case of large temperature difference thermoelectric generators need integration of large number of individual thermo-junctions. Printing technologies enhance effective production of integrated thermo-generators with individual junctions connected in series.
