ABSTRACT
The performance of a semiconductor thermoelectric generator system based on the Lower Convective Zone of a salt gradient solar pond and ambient has been studied numerically and experimentally. According to the numerically solar pond temperature development results, the temperature differential range of the thermoelectric generator system ranges from 14 to 36°C. The numerically results show that, with a load resistance of 2Ω for each thermoelectric generator unit, among the four days selected, the temperature difference power generation system had the highest output power and conversion efficiency of 4.66W and 2.95%, respectively, on October 1st. Based on the numerical results of the temperature developments salt gradient solar pond, thermoelectric power generation experimental setup which operates under adjustable hot and cold reservoirs has been constructed. The experimental device runs under the conditions that the cold side temperatures of thermoelectric generator are 10°C, 24°C, and 38°C, and the load resistance is 10Ω. The maximum current is 0.149 A, 0.159 A and 0.124 A, the maximum voltage is 1.49 V, 1.59 V and 1.24 V, respectively. The average deviations between the theoretical results and the experimental results of the current and voltage generated by the power generation system are 0.026 A, 0.023 A, 0.012 A and 0.26 V, 0.23 V, 0.12 V, respectively.
