In the same figure, we provided the model base power assuming for the TE generator an internal resistance (Rint) of 1.75 U and an open-circuit voltage (Voc) of 2.65 V for comparison.The comparison between the experimental results and that of the model permits to validate the experimental procedure.The variation of the voltage (Vo) and output power (Po) characteristics for an electric load of 2 U of the TE module as a function of the temperature difference (DT) between the hot side and cold
side of the TE module is shown in
