Sizing the height and cross sectional area of the pellets within thermoelectric modules (TEMs) used to cool, heat and generate power is necessary to optimize their efficiency and/or performance. Here the heat flux that a TEM can accommodate, its coefficient of performance, and its operating current and voltage in refrigeration mode are provided as a function of pellet geometry. This enables designers to, for example, size pellets to refrigerate a load such that the total power consumption of a TEM and a power supply (that converts available voltage to that required by the TEM) is minimized. In generation mode, power output, conversion efficiency and operating voltage and current are provided as a function of pellet geometry and the electrical resistance of a load connected to a TEM. Finally, the effects of electrical contact resistance at the pellet interconnects on the aforementioned parameters are addressed.
