Organic-inorganic nanojunctions can result in a selective scattering of charge carrier depending on their energy, which leads to a simultaneous increase in the Seebeck coefficient.. and the power factor. In this work, the nanojunction is successfully employed at the organic-inorganic semiconductor interface of polyparaphenylene (PPP) and Zn1-xAgxO nanoparticles through the sol-gel method. The presence of nanoinclusions PPP in Zn0.9Ag0.1O matrix is found to be effective in improving the figure of merit (ZT) by the dual effects of an increase in the power factor consistent with the heterojunction effect and a reduction in thermal conductivity. Zn0.9Ag0.1O/0.1 wt% PPP exhibits a maximum figure of merit, i.e., ZT=0.22.
