Correlation between growth parameters and thermoelectric efficiency of PEDOT-Tos thin films for energy harvesting applications

Résumé

For years, materials are competing for the best thermoelectric properties through the enhancement of the figure of merit ZT. After metals and semiconductors, oxides and polymers are today in the front. In the same time, the way to evaluate the ZT property is often a problem because of the plural techniques and systems of measurement. The last development in the laboratory consists in a complete setup for the simultaneous evaluation of the Seebeck coefficient, electrical and thermal properties of the thermoelectric material, that we call ZT-meter. With this microscale device, we performed a deeply analysis of the thermoelectric behaviour of concerned materials. Evolving in a national project called Tours2015, we are actually studying different sputtered PEDOT-Tos polymer thin films deposited on silicon, in order to correlate the growth parameters with the thermoelectric properties. With ZT values expected above 0.2, these materials could be serious candidates to be used later on as a new micro-source of energy.
