Modeling of a concentrating photovoltaic module

Abstract

The photovoltaic systems are characterized by low efficiency. To improve their efficiency we need to use concentrating photovoltaic systems. These CPV systems allowed the enhancing of the power which received by the cell. This high power can raise the potential of the electrons causing the heating of the cell, which minimizes the photovoltaic efficiency of the module. This work has the role to model a concentrating photovoltaic module without and with cooling system. We have established a theoretical model based on energy balances. Using MATLAB, the obtained results, allow us to compare between CPV module with and without cooling system and to know the importance of adding the cooling system. Those results indicated the improvement of CPV systems' efficiency.
