This work, based on the junction recombination velocity (Sf_u) concept, is used to study the solar cell’s electric power at any real operating point. Using Sf_u and the back side recombination velocity (Sb_u) in a 3D modelling study, the continuity equation is resolved. We determined the photocurrent density, the photovoltage and the solar cell’s electric power which is a calibrated function of the junction recombination velocity (Sf_u). Plots of solar cell’s electric power with the junction recombination velocity give the maximum solar cell’s electric power, P_m. Influence of various parameters such as grain size (g), grain boundaries recombination velocity (Sgb), wavelength (λ) and for different illumination modes on the solar cell’s electric power is studied.
