A Computationally Efficient Multidiode Model for Optimizing the Front Grid of Multijunction Solar Cells under Concentration

Figure 5

(a) Open circuit voltage, (b) fill factor, and (c) short circuit current density as a function of periodicity for 0%, 50%, and 100% redirection. The graph shown is simulated under 300x concentration. The decrease in current and voltage at low periodicities is strongly reduced with increasing redirection.
