Its the same effect as the heat temperature driven potentials derived
in a thermocouple only in reverse. A current passed through dissimilar
materials will pump heat from one side of the junction to the other.
A physics text book should give a good explanation of the Peltier
effect - much better than any handwaving I could do.
