Abstract

We demonstrate dual junction (Al)GaInP/GaAs solar cells that are designed to operate at 400 degrees C and 1000X concentration. The cells have stable front metallization and anti-reflection coatings at 400 degrees C. The choice of bandgaps was first estimated using ideal solar cell characteristics and then refined based on empirical data. We show power conversion efficiency of ~15 +/- 1% for AR-coated cells at 400 degrees C and high concentration, with pathways to improved performance.
