Kang-Snyder model applied to various P3HT-inorganic composites. a The electrical conductivity vs Seebeck coefficient data of F4TCNQ doped P3HT (closed circles)31, Fe((CF3SO2)2N)3 doped P3HT (open squares)32, highly aligned P3HT with trichlorobenzene (closed squares)33, P3HT:MWCNT (closed triangles)35,36, P3HT:SWCNT (open star)37,38 and P3HT:Bi2Te3 (closed stars)34 hybrid systems. It is seen that experimental data lies on s = 3 curve, again consistently identical for the hybrid and the pure polymeric systems. b Comparison of power factor of PEDOT (s = 1) and P3HT (s = 3) based hybrids. Targeting higher \({\mathrm{\sigma }}_{{\mathrm{E}}_0}\sim 10\,{\mathrm{S/cm}}\) in a s = 3 polymer can push power factors of hybrid materials towards values comparable to inorganic thermoelectric materials
