Abstract

In this study, we fabricated a thermoelectric module made of nanoparticles (NPs) and glass fibers investigated its thermoelectric characteristics. P-type HgTe and n-type HgSe NPs synthesized by colloidal method were used as thermoelectric materials and glass fibers were used as spacers between the hot and cold electrodes of the thermoelectric module. In the module, the average Seebeck coefficients of the HgTe and HgSe NPs were 1260 and $-628{\mu}V/K$, respectively. The p-n module generated about a voltage of 11.9 mV and showed a power density of $1.6{\times}10^{-5}{\mu}W/cm^2$ at a temperature difference of 7.5 K.
