3.4.3. Single Stage Segmented Arrangement

The maximum efficiency of the single stage segmented arrangement of the thermoelectric module with two leg geometries and combination of SiGe+Bi2Te<sup>3</sup> material increased with the temperature difference. The maximum efficiency variation with the temperature difference is shown in Figure 8c. Like maximum power, the leg geometries had no effect on the maximum efficiency of the single stage segmented arrangement of the thermoelectric module with two leg geometries and combination of the SiGe+Bi2Te<sup>3</sup> material [1,6,10]. At a temperature difference of 730 ◦C, the square prism and cylindrical legs showed maximum efficiency of 13.2%.
