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 S and the power factor.In this work,the nanojunction is successfully employed at the organic-inorganic semiconductor interface of polyparaphenylene(PPP)and Zn_(1-x)Ag_xO nanoparticles through the sol-gel method.The presence of nanoinclusions PPP in Zn_(0.9)Ag_(0.1)O 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.Zn_(0.9)Ag_(0.1)O/0.1 wt%PPP exhibits a maximum figure of merit,i.e.,ZT=0.22.
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 S and the power factor. In this work, the nanojunction is successfully employed at the organic-inorganic semiconductor interface of polyparaphenylene (PPP) and Zn_ (1-x) Ag_xO nanoparticles through the sol-gel method. The presence of nanoinclusions PPP in Zn_ (0.9) Ag_ (0.1) O matrix was found to be effective in improving the figure of merit ) by the dual effects of an increase in the power factor consistent with the heterojunction effect and a reduction in thermal conductivity. Zn_ (0.9) Ag_ (0.1) O / 0.1 wt% PPP exhibits a maximum figure of merit, ie, ZT = 0.22 .
