Abstract
III-V InGaP/InGaAs/Ge triple junction solar cells have been developed which incorporate quantum wells into the InGaAs and InGaP junctions. Characterization of such devices shows an absolute efficiency gain of up to 2% with Voc exceeding that of non-QW devices. Cells grown on 6â² wafers with quantum wells in the InGaAs junction are now commercially available with median efficiencies above 41%.
