Abstract

Thermoelectric (TE) is the direct conversion of temperature difference between the junctions of two dissimilar materials to provide electrical output. This effect was discovered by Thomas Seebeck in 1821. Later, in 1851, Peltier showed the converse is also true. The Seebeck effect could be utilized to generate electricity and the Peltier effect could be utilized as a heat pump for the cooling of semiconductors like LEDs. This paper reports on the performance of TE modules. Thermal characteristics such as the Seebeck coefficient (αte), thermal conductance (Kte), internal resistance (Rte), power load (PL) and Coefficient of Performance (COPc), were determined in this study. Experiments were conducted using TE in both power generating (TEG) and in cooling (TEC) modes. The Seebeck coefficient and thermal conductancewere found to be quite constant but the internal resistance increased as the temperature increased. The coefficient of performance was found to decrease with power supplied to the TE. Recommendations for future studies were suggested to improve the present study.
