Year: 2010

Type: article

Abstract: The paper deals with a coating CuO thin film coating on the surface of semiconductor thermoelements (Bi2Te3). In addition, the recycled external exhaust heat is used to generate electric power, further enhancing the thermoelectric conversion efficiency of the thermoelectric generator (TEG). By using electrophoresis deposition, a CuO nanofluid with high suspension stability and good dispersion is deposited on an aluminum foil at a thickness of 0.1mm. This film is conjugated with the top and base of a semiconductor thermoelements (Bi2Te3), and a thermoelectric generator is assembled in parallel with the modified thermoelectric material. Experimental results show that the CuO nanofilm coating on the surface of semiconductor thermoelements can enhance the overall heat conduction and thermoelectric conversion efficiency of thermoelectric generators by as much as 30%.
