Abstract
Thin gallium-arsenide (GaAs) solar cells manufactured through epitaxial liftoff can offer high-efficiency, reduced costs and high power to weight ratios perfect for UAV applications. Alta Devices, in particular, is one thin-film GaAs manufacturer which holds world records for terrestrial solar cell conversion efficiency of single and dual junction cells. As a result, this solar technology is capable of increasing UAV endurance indefinitely in some instances. Ultimately, solar cell price and performance will be key to the UAV industry’s ability to grow (especially for high-altitude long endurance or beyond visual line of sight applications) by providing increased endurance through a renewable energy source. This presentation will provide an overview of applicable solar performance metric for UAVs, the different solar technologies available, show the advantage of thin-film GaAs , and present applicable case studies.
