Figure 5. (A) Schematic of TGCs containing only I-/I3- (n-type) and pNIPAm/(I-/I3-) (p-type). (B) The phase change of pNIPAm nanogels and the redox reaction of I-/I3-. (C) Concentration change ratio of I- and I3- at different temperatures. (D) Voc as a function of temperature difference with and without pNIPAm nanogels in the I-/I3- electrolyte. (E) I-V curves and corresponding power at
