Commercial concentrator systems yield to non-uniform illumination profiles. This is a source of degradation for the performances of solar cells and further worsen by the consequent non-uniform temperature distribution. The modelling of these effects can be effectively performed only if three-dimensional effects due to the lateral flow of the current into the emitter are taken into account. In this paper, a three-dimensional model allowing to evaluate the behaviour of solar cells under arbitrary non-uniform illumination profile is presented. Numerical simulations were performed in order to evaluate the effectiveness of the model.
