Thermoelectrical Characterization of Organic Materials

Organic semiconductors are prime candidates for thermoelectric applications, because one can maximize the dimensionless figure of merit ZT (by maximizing the Seebeck coefficient and electrical conductivity) while simultaneously minimizing the thermal conductivity. In this work, we explore a few mate...

Description
Summary:Organic semiconductors are prime candidates for thermoelectric applications, because one can maximize the dimensionless figure of merit ZT (by maximizing the Seebeck coefficient and electrical conductivity) while simultaneously minimizing the thermal conductivity. In this work, we explore a few materials and try to find their thermoelectric characteristics. For the n-leg of the thermogenerator, we studied a modified fullerene (PCBM) which is doped with TDAE vapor. For the p-leg, we studied PEDOT and found the TDAE dedoping level at which the figure of merit is maximized.
