Using EtaOpt the detailed balance efficiency of the classic lattice matched InGaP/GaAs/Ge 3-junction cell and those of optimized band gap combinations for both monolithic and mechanical stacks are calculated under 500×AM1.5D illumination. The results are 48.7% (mono) and 59.2% (mech) for the classic and 59.6% (mono) and 60.3% (mech) for the optimized band gap structures. For these devices we calculated the (ideal) annual energy yield (AEY) under realistic spectra that represent a typical… CONTINUE READING
