Abstract
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.
