Fig. 2. Thermopower enhancement and polarization switching from n-type to p-type for the I−/I3− redox couple induced by MC.

Fig. 2.

(A) Recorded open-circuit voltages with the increase of the hot electrode temperature for the I−/I3− + x MC electrolytes (x = 0, 1, 2, 5, and 8 wt %). The cold electrode temperature is held at 24°C. (B) Extracted mean thermopowers of the I−/I3− + x MC electrolytes. (C) Schematics of the polarization switching from n-type (Th < TTra) to p-type (Th > TTra) induced by the gelation of MC.
