Composites made of semiconducting carbon nanotubes and p‐type polymers, when adequately doped with molecular dopants, can exhibit highly delocalized charge carrier transport, showing high thermoelectric performances. The efficient charge delocalization is enabled by the reduced coulombic binding energy at high carrier concentration and the small ...

The study demonstrates that dip coating at lower speeds significantly enhances the thermoelectric performance of P3HT by improving electrical conductivity. Contrary to expectations, this improvement is seemingly not due to polymer alignment but rather to better structural order achieved during slower solvent evaporation at lower dip coating speeds ...

A novel n‐dopant, phosphazenium tetrafluoroborate (P2BF4), is introduced for efficient n‐doping in N2200, P(PzDPP‐CT2) and other organic semiconductors (OSCs). P2BF4‐doped OSC films exhibit exceptional thermal stability, maintaining electrical conductivity after heating at > 150 °C for 24 h. This stability allows organic thermoelectric devices based on

Proton‐coupled electron transfer doping with benzoquinone is applied to p‐dope dense films of semiconducting single‐walled carbon nanotubes. The doping efficiency depends on the pH of the doping solution and the bandgap of the nanotubes. The highest conductivities and power factors are achieved for small‐bandgap nanotubes, remaining stable for over 120

Combining high polymer orientation of n‐type copolymers by temperature rubbing and sequential doping with N‐DMBI results in a strong improvement of electrical conductivity and thermoelectric power factors reaching up to 9.8 ± 1.6 S cm−1 and 8 ± 3 µW m−1.K2, respectively.

Modification of polymer backbone via halogenation and comonomer selection leads to conjugated backbones of different stereoelectronic properties, thin film morphologies, and electrical characteristics. The interplay of conformational isomerism, coplanarity, backbone curvature, backbone orientation, and ordering in thin films, electrical conductivity ...

Effect of Regiochemistry on Doping and Thermoelectric Properties of n‐Doped Fullerene Derivatives
Three fullerene derivatives doubly substituted with diethylene glycol chains (PDEG‐2) is presented. The different regiochemistry significantly affects the crystallinity and consequently the dielectric properties, electronic transport, and doping efficiency. By striking a balance between compatibility with the molecular dopant N‐DMBI and crystallinity a
