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

Figure 6

Maximum achievable efficiencies for various values of redirection capability, as a function of finger periodicity. It is shown that significant efficiency gains can be obtained by increasing the amount of redirection and moving to lower periodicities. The dashed yellow curve indicates the result presented in [22]. Note that the maximum efficiencies occur at higher concentrations when going to lower periodicities and higher redirecting capabilities (see Figure 7).
