The electrical resistance of Thermoelectric generator

I have built a simple thermoelectric generator(TEG) with one P leg and one N leg connecting to a external load resistance through the "Electrical circuit". After setting material type, the hot and cold side temperature, I did a parameter sweep on external load resistance Re to get the maximum output power of the TEG. Theorectically, the external load resistance Re corresponding to the maximum output power should be equal to the internal electrical resistance of the TEG. However, the Re corresponding to the maximum output power from the simulation is always larger than the internal electrical resistance of the calculation results( which is the sum of electrical resistances of copper electrodes and TE legs), see the attached picture. Could someone explain why this happens? Many thanks~
