Thermoelectric energy conversion that converts waste heat into electricity has attracted much attention as a potential clean energy technology. The performance of thermoelectric materials is determined by the dimensionless figure of merit (ZT), which is equal to σS2T/κ where the κ is the thermal conductivity, the S is the Seebeck coefficient and the σ is the electrical conductivity. The σS² stands the power factor. Even though a low k and a high-PF are needed to reach high ZT values, the conflicting relationship between the S and the σ limits the further modulation of ZT of thermoelectric materials. Conducting polymers are promising to be the next generation of thermoelectric materials. They have intrinsical... view more»
