The Effect of Temperature Mismatch on Interconnected Thermoelectric Module for Power Generation

摘要

This study focus on the different effect of temperature mismatch of the thermoelectric generator with the different thermoelectric module. The demand for renewable energy sources as an alternative energy has been increasing with the development of technology. Generating electricity using thermoelectric modules is one of the innovative method that will be discussed in this paper. This study includes analyzing the electrical characteristics of the thermoelectric modules under temperature mismatch conditions. Thermoelectric generators are used for direct conversion of heat energy to electrical energy when there is a temperature difference using the working principle of Seebeck effect and Peltier effect. The thermoelectric module that will be used were coded as TEC1-12703 and TEC1-12706. The hot side of the thermoelectric module will be heated using the heat energy from the sun and heat sink will be used to remove the heat for the cold side of the thermoelectric generators. The thermoelectric generator will be tested and the data acquired will be focused on the voltage output produced, ampere output and power output. In TEG system, usually individual thermoelectric module are subjected to temperature mismatch because of operating conditions. The temperature mismatch condition influences the decrease in power output produced due to different electrical operating point in the TEG array.
