a Simulated efficiency (η) with respect to the Ap/An ratio and the working current (I) for the single-stage module (n-Sb0.7) under Thot = 543 K and Tcold = 293 K. b Measured electrical contact resistivity at the n-type/Fe and p-type/Ag junctions. The red circles and blue diamonds represent the scanning resistance across the junctions, the solid horizontal lines indicate the contact resistivity.
