In this study, SnO2 nanoparticle in different wt% ranging from 2, 4, 6 and 8 were uniformly composite in Bi2Te3 matrix. SnO2 nanoparticle was synthesized using sol-gel method. The SnO2/Bi2Te3 nanocomposite was consolidated by solid state method. The thermoelectric properties of the bulk samples were investigated in the temperature range from 300 to 500 K. The value of electrical resistivity increased with the addition of concentration of SnO2 nanoparticle. On the other hand, the Seebeck coefficient decreased with the increment of SnO2 nanoparticle. Although, in the sample of 4% SnO2/Bi2Te3 reach the highest value of absolute Seebeck coefficient. The maximum value of power factor has been achieved at temperature of 325 K about 4.0×10^(−3)Wm^(−1)K^(−1) in the sample of SnO2/Bi2Te3 nanocomposite with 4% SnO2 nanoparticle. This results demonstrating that the thermoelectric properties of Bi2Te3 can be effectively improved by incorporation of SnO2 nanoparticle.
