Abstract

The present theoretical analysis focused on the investigation of a new design extended and tapering segmented pin configuration based thermoelectric generator (TEG) incorporating with modified bismuth and lead telluride materials. With the current design, the system can operate at two different cold junctions. Effect of thermal performance, i.e., heat transfer rate from the cold and hot side, maximum efficiency, overall efficiency, second law efficiency, entropy generation, normalized work and efficiency ratios on the variation of designed shape factor, load resistance ratio, temperature ratio, and p-n junction lower temperature difference have been considered.
