The performance improvement of a concentrated photovoltaic-thermoelectric system by exploiting thermoelements with altered cross-sections is presented. The regular rectangular cross-sectional area adopted in thermoelectric devices is replaced with circular cross-sectional area and the accuracy of the numerical results are established by comparisons with experimental data. The numerical model is setup in ANSYS software and thermoelectric material temperature dependency is considered. The optimized parameters of the system include the solar concentration ratio, convective cooling, ambient temperature, and the wind speed while the performance parameters are the solar cell temperature, system power, energy efficiency, and thermoelectric generator temperature difference. It was found that the proposed system with circular legs improved the power and energy efficiency of the conventional system with rectangular legs by 226% and 68% at a concentration ratio of 45, respectively. The optimum design conditions necessary for fabricating the proposed device using additive manufacturing technology are also provided.
