FY19 ANNUAL REPORT

Dragon SCALEs — miniature solar cells, also known as “solar glitter.” Prototype of the small, lightweight, flexible solar cells that fit into and power devices or sensors of any shape or size.

Power Bus Grand Challenge (GC) capabilities could reduce time/cost of nuclear system upgrades. The Power Bus GC resulted in the development of key technologies to enable power distribution and conversion in extreme environments. In particular, the Power Bus team developed power

conversion circuits using custom semiconductor devices, fabricated at Sandia, that can operate at higher voltages while maintaining an intrinsic resilience to high temperature and intense radiation. The new technology was designed for power distribution in national security applications and other high consequence systems. Partnerships will continue with the Office of Naval Research on electric ship applications, DOE Vehicle Technologies Office’s Electric Drive Train Consortium on electric vehicles, the ARPA-E, and two R&D Certification and Safety projects.
