Abstract: This study deals with the modelling of segmented thermoelements for Radioisotopic Thermoelectric Generator. One of the more important quantities for a thermoelement as well as for any device is its efficiency. As far as a thermoelement with segmented legs is concerned, it is not an easy task to evaluate its efficiency. In a first step, approximations are made and the values of the thermophysical and thermoelectrical parameters are assumed to be constant (mean values are used to perform calculi). Then a more complete modelling is proposed: the thermo dependence of the parameters is taken into account. The compatibility of the thermoelectric materials is checked and an optimization is be made in order to determine the value of the relative current density that allows to maximize the efficiency of the thermoelement.
