Thermoelectric (TE) Materials and Devices

We are focusing on the material synthesis, both in bulk and thin film forms. Our main contributions have been the discovery of suitable dopants for thermoelectric compounds alternative to Bi2Te3 based materials. 

 

Currently, we are developing new ink formulation processes to print hybrid organic-inorganic materials. 

 

We are actively contributing to the European Project called Thermocool, to test newly developed  materials in real environment.

 
Figure. The printed TEG stack and module based on TiS2/HA films. A) Sketch of a TEG stack made of eight TiS2/HA legs connected in series. B) Power output generated by the TEG stack at different temperature gradients. The cold side is at 302K for the three temperature gradients and the hot side is at 322K, 332K and 342K for the gradients of 20K, 30K and 40K, respectively. C) Picture of a TEG module with 3 serial stacks. D) The voltage generated by a TEG module as a function of the number of stacks.
