Abstract
Multi-junction solar cell devices which incorporate dilute nitrides to include a sub-cell in the 1 eV range in a conventional design for a solar cell. Sub-cells may be inserted within the intrinsic region of a conventional GaAs p-i-n solar cell either as a 3rd junction (1 eV) in a (Al)InGaP (1.9 eV)/GaAs(1.42 eV)/MQW(1 eV)/Ge(0.66 eV) quadruple junction device or as a triple junction configuration with a 1.1 eV MQW between GaInP (1.8 eV) and Ge(0.66 eV).
