Original Paper


This work, based on the grain size concept, is used to study a 3D Modeling of silicon solar cell’s capacitance efficiency on the extension space charge region with garin size. The effect of grain size, incidence angle and depth z (cm) in the base have been discussed. Using incidence angle in a 3D modeling study, the continuity equation was determined. We resolute the photocurrent density, the photovoltage, also we solved the diffusion equation of the minority carriers in the base, the transmitter is not taken in account and we drawed the analytical expression of the density. Plots of silicon solar cell’s capacitance efficiency with the grain size give the maximum solar cell’s capacitance efficiency. Capacitance efficiency affects various parameters of a grain size (g).
