From: Performance assessment of multijunction solar cells incorporating GaInNAsSb

  Jsc(GaInP) + Jsc(GaAs)(mA/cm2) Jsc(GaInNAsSb) + Jsc(Ge)(mA/cm2) Difference (mA/cm2) Jsc-current matched 3J(mA/cm2) Jsc-current matched 4J(mA/cm2)
AM1.5G 31.9 25.0 −6.9 14.52 12.94
AM1.5D 30.3 28.4 −1.9 13.79 13.35
AM0 39.0 36.1 −2.9 17.75 17.09
  1. Jsc values shared by GaInP/GaAs and GaInNAsSb/Ge junctions for different spectra at 300 K [12] and the current matching Jsc values with EQEav = 0.91 for GaInP/GaAs/GaInNAsSb and GaInP/GaAs/GaInNAsSb/Ge. The Jsc differences between the two top junctions and the two bottom junctions are also given.
