Abstract: This paper shows the irradiation effect on a solar cell capacitance under monochromatic illumination in dynamic frequency mode. From the continuity equation, we determine the expression of excess minority carrier density from which the capacitance and the capacitance efficiency are deduced thereafter studied according to the modulation frequency and the irradiation energy. This paper shows that the capacitance efficiencyand the thickness of the space charge region (SCR)in short-circuit decrease accordingto the irradiation energy increasing.
