A comparison of quantum dot (QD) triple-junction solar cells (TJSCs) with the QD superlattice under tensile strain are compared with those under compressive strain and baseline devices to examine the effects of strain induced by the InAs QD layers in

InAs quantum dots (QDs) have been incorporated to bandgap engineer the (In)GaAs junction of (In)GaAs/Ge double-junction solar cells and InGaP/(In)GaAs/Ge triple-junction solar cells on 4-in. wafers. One sun AM0 current–voltage measurement shows con

Predicting the output of the Solar Probe Plus (SPP) solar array presents unique challenges as the array operates at very high temperatures and irradiances, and has a water-cooled substrate. A further complication arises because, close to perihelion,

NASA's Solar Probe Plus (SPP) will travel closer to the Sun than any previous spacecraft. During its 7-year, 24-orbit mission, SPP will make scientific measurements of the solar corona, reaching minimum perihelion at ~9.5 solar radii (Rs) from the ce

Lattice matched, triple-junction solar cells with strain-compensated quantum dots (QDs) in the GaAs middle cell were grown by Metal-Organic Chemical Vapor Deposition (MOCVD). Devices with different numbers of QD layers are compared to baseline device

A comparison of quantum dot (QD) triple junction solar cells (TJSCs) under tensile strain are compared to those under compressive strain and baseline devices to examine the effects of strain induced by the QD layers. It is found that tensile strain l

Intermediate band solar cells using quantum dots (QDs) have been proposed as an approach to increasing solar cell efficiency [1]. This paper presents results of attempts to grow QDs in the GaAs middle cell of lattice matched triple junction solar cel

The Solar Probe Plus (SPP) spacecraft will fly further into the Sun's corona than any previous mission, reaching a minimum perihelion at 9.5 solar radii from the center of the Sun. The solar arrays powering the spacecraft will operate under unusually

Radiation tolerance of quantum dot (QD) enhanced solar cells has been measured and modeled. GaAs solar cells enhanced with 10, 20, 40, 60, and 100X layers of strain compensated QDs are compared to baseline devices without QDs. Radiation resistance of
