Summary form only given. The highest solar cell conversion efficiencies are achieved with Four-junction devices under concentrated sunlight illumination. Different cell architectures are under development, all targeting an ideal bandgap combination close to 1.9 eV, 1.4 eV, 1.0 eV and 0.7 eV. Wafer bonding is used in this work to combine materials with a significant lattice-mismatch. Three cell architectures are presented using the same two top junctions of GaInP/GaAs but different infrared…
