-ect of Spectrum Range Limitation (SRL) to the efficiency and performances of multijunction solar cells • 7As/GaAs/lnP/Ge was investigated using simulation approach. Simulations were done using two different first with No Spectrum Range Limitation (NSRL) and the second with SRL. In the first model each subcell I) was free to absorb AM l .5G solar radiation spectrum from 280 nm up to 2500 nm, while for the second model. rption spectrum for each subcell depends on the cut-off wavelength of its previous subcell. For each model. a tical current flow in each layer was simulated. The results have shown that SRL dropped the efficiency by a half (44.90 %) compared to simulation with NSRL. All current-producing simulations were performed using 11 ailable PC ID program.
