Abstract

Thermoelectric(TE) conversion devices can directly convert heat to electricity. Lead Telluride are known for fabulous thermoelectric material in 600-900K temperature range. It is suggested that power factor of this material can be enhanced by incorporating group III dopants through a distortion of the electron density of state i.e., the resonant level. Therefore, we synthesized In doped PbTe and measured its thermoelectric properties. Seebeck coefficient increase -50μ V/K(R.T) to -330 μ V/K as temperature increase. Electrical conductivity decrease 1000 S/cm(R.T) to 100 S/cm as temperature increase. Thermal conductivity decrease 2.3W/mK(R.T) to 1.2W/mK. As a result. In0.1at% PbTe has Thermoelectric figure of merit ZT-0.7 at 775K.
