  • Abstract
    High-efficiency 1.0 eV GaInAs cells for ultimate integration into AlGaAs/GaAs/GaInAs 3-junction, 2-terminal monolithic devices are described. An n/p 1.0 eV GaInAs cell has been fabricated with a 4.7% (5.4%) solar conversion efficiency under 1-sun, 25°C, AM0 (AM1.5 G) conditions underneath a simulated GaAs cell. While this GaInAs cell had a AM0 Jsc of 14.6 mA/cm2, at least 16 mA/cm2 is needed to current match the AlGaAs and GaAs upper cells. A recent n-i-p 1.0 eV GaInAs cell achieved a Jsc of 16.0 mA/cm2. Progress toward monolithic integration with the AlGaAs/GaAs upper cells is described
