Abstract: Traditionally only symmetrical leg configurations were employed to evaluate the performance of the thermoelectric generator. With modern manufacturing technology, the complex shape of a thermoelectric leg can be made cost effectively. The current study proposes a novel design of a thermoelectric generator with asymmetric and segmented leg configurations with materials of modified lead telluride (material-1) and modified bismuth telluride (material-2). The p-type leg of traditional flat plate geometry and n-type leg of exponential variation area with geometric parameter ‘a’ is considered. The effect of efficiency, work output, work ratio and output current on the geometric parameter with temperature ratios and load ratios of the designed thermoelectric generator were investigated.
