Abstract

Process for manufacturing thermoelectric devices that may indistinctively work under the seebeck or peltier regime, having an electric interconnection in series and a thermal distribution in series or parallel, as well as devices of flat circular geometry and/or angular geometry and/or squared geometry, or flat rectangular geometry and/or angular geometry which are useful for substantially improving the electrons flow by alternating similar metals and using the different electronic properties thereof, in order to manufacture cold and hot electrodes, for instance: cooper and silver, so as to eliminate the dipolar coat formed by using the same metal in both electrodes. Said coat causes a great percentage of the current generated by the thermoelectric device to be annulled, thereby producing a great efficiency in the performance of the thermoelectric device. The fact of selecting different metals, due to the electronic properties thereof, for manufacturing hot and cold electrodes provide s said electrodes with a novel electronic function upon removing the dipolar coat and aiding to the electrons flow, which differs from their traditional function of electric and thermal conduction. The said process allows the thermoelectric devices to have more electronic and thermal efficiency and capacity. Moreover, the side of said thermoelectric element that generates the higher performance is easily detected provided that the thermoelectric device is between the electrodes of different metals; and an additional and substantial increase in the performance of the element is obtained upon positioning in a correct manner the electrodes. The abovesaid effect is not detected using electrodes manufactured with the same metal, for instance cooper, due to the losses generated in the dipolar coat that is formed.
