Abstract

As the world leader in volume production of large-area epitaxial lift-off (ELO) III-V inverted metamorphic multi-junction (IMM) solar cells, MicroLink proposes to develop phosphide-based ELO-IMM four-junction (4J) and five-junction (5J) solar cells that will enhance the performance and capabilities of solar photovoltaic arrays for a variety of future NASA missions. Relative to state-of-the-art incumbent (Al)GaInP/GaInAs/Ge wafer-based 3J space solar cells, the proposed 4J and 5J solar cells have superior radiation tolerance, higher beginning-of-life (BOL) and end-of-life (EOL) efficiencies (η), lower areal mass density, higher specific power, higher operating voltage, lower cost, and inherent flexibility.
