- W2510991300 abstract "The open circuit voltage V{sub oc} and reference voltage V{sub ref}, defined as a measure of the dark current quality, have been studied for a large number of quantum well (QW) solar cells and homogeneous control cells.Samples were grown in the Al{sub x}Ga{sub 1{minus}x}As/GaAs and GaAs/In{sub y}Ga{sub 1{minus}y}As material systems. For both combinations, QW solar cells show a better voltage performance in V{sub oc} and V{sub ref} than one would expect from a single bandgap solar cell with the same effective absorption bandgap E{sub a}. For the AlGaAs/GaAs cells, V{sub oc} is related to structural parameters of the QW cells such as the well width L{sub W} and the Al fraction x. For the strained GaAs/InGaAs cells a relationship is found between V{sub ref} and the barrier width L{sub B}, which is a dominant parameter in determining strain relaxation and defect formation at a fixed In fraction." @default.
