Impact of the dopant location in the semi-crystalline structure of alternated donor–acceptor copolymers on the polarity switching p → n mechanism

Abstract

The location of dopants in the crystalline and/or amorphous domains of D–A polymers determines the polarity switching of the Seebeck coefficient.

Influence of the electronic structures of diketopyrrolopyrrole-based donor–acceptor conjugated polymers on thermoelectric performance

“…These spectral changes indicate that the CN series films were heavily p-doped, resulting in the formation of polaron states. 37–39 In Fig. 3a, the UV-vis-NIR absorption spectra of the 5 mM FeCl 3 -doped CN series films were normalized to the neutral polymer peaks to compare the polaron peak intensities of the P1 and P2 bands.…”
