MicroLink Devices' multi-junction ELO solar cells are well-suited for future very large solar arrays to support solar electric propulsion (SEP) missions. Conventional solar-powered satellites can also benefit from lower-cost alternatives to existing Ge-based multi-junction solar cells. The cells are useable in solar-powered unmanned aerial vehicles (UAVs). MicroLink Devices' multi-junction ELO solar cells are a potential replacement for conventional solar cells for military and civilian applications. The combination of high efficiency and low weight also make the cells ideal for powering unmanned aerial vehicles (UAVs). There are also emerging military and commercial applications for high-efficiency, flexible solar sheets for terrestrial power generation.
