Abstract

The objective of this study is to present and explain theoretically the influence of irradiation energy on the diffusion capacity of a bifacial CuInGaSe2 solar cell under monochromatic illumination in dynamic frequency regime. Using the equation of continuity of the minority charge carriers in the base, the density of these carriers is determined. Then the expressions of the phototension are deduced. From these quantities the expressions of the capacitance are calculated and the representations of the curve of these parameters as well as the representation of the BODE diagram are interpreted. The obtained values are proposed with the effect of the irradiation energy.
