     established thermoelectric theory enables direct calculation of the power output and conversion efficiency if the temperature difference across a module is given. however, in some applications such as those using a radioisotope or solar radiation as a heat source, the thermal input remains constant while the temperature difference varies with the geometry of the thermoelectric module. in this paper, a theoretical framework for thermoelectric module design under a given thermal input is presented. it provides a convenient approach for module geometry optimization. the usefulness of the theory is demonstrated through a design study, in which an appropriate thermoelement length for a solar thermoelectric system is determined by considering conflicting requirements for a longer length to obtain a greater temperature difference and for a shorter length to produce a larger power output.
