Thermoelectric (TE) materials transform thermal energy into electricity, which can play an important role for global sustainability. Conducting polymers are suitable the preparation of flexible TE because their low-cost, lightweight, flexible, and easily synthesized properties. Here, we fabricate organic-inorganic hybrids by combining vanadium oxynitride nanoparticles coated with nitrogen-doped carbon (NC@VNO) poly(3,4-ethylenedioxy thiophene):poly(styrene sulfonate) (PEDOT:PSS). We find that electrical conductivity, Seebeck coefficient, power factor NC@VNO/PEDOT:PSS film be enhanced up to 4158 S/cm, 45.8 μV/K, 873 μW/mK
