AbstractDeployable Space Systems (DSS), in partnership with ATK Space and EMCORE, is focusing on the design development and optimization of the most promising advanced space photovoltaic subsystem now available: EMCORE's ultra-thin 33% BOL-efficient Inverted Metamorphic Multijunction (IMM) solar cell that is interconnected into module form and integrated onto an advanced flexible blanket (gore); specifically for implementation on the lightest solar array structural system currently in use, ATK's UltraFlex. The innovative and synergistic solutions conceptually developed during the Phase 1 effort produced a near-term, low-risk solar array system that provides breakthrough performance in terms of highest specific power (>380 W/kg BOL), light weight, scalability to large (>15 kW) wing sizes, high deployed stiffness, high deployed strength, compact stowage volume (>40 kW/m3 BOL), high voltage operation capability, reliability, affordability, and rapid commercial readiness. The Phase 2 study will successfully further increase the design fidelity (TRL) of the most promising IMM-integrated onto UltraFlex-specific triangular gore blanket solutions configured to meet key high-voltage SEP / deep space science mission requirements. The development, as performed on the cost-effective Phase 2 SBIR plan structured in detail, will allow for an expedient and low-risk commercial infusion of the ultra-lightweight integrated IMM PV UltraFlex solar array technology via continued hardware-based and test-validated development, and enables future missions, including near-to-medium term NASA Outer Planets and Solar Electric Propulsion (SEP) science missions.
