The cost-reduction paths for space GaAs solar cells are narrowing simultaneously from two independent directions. 1. Push “Thinness” to the Limit and Recover What Is “Expensive” Flexible gallium arsenide (GaAs) solar cells less than 0.1 mm thick are being efficiently produced on production lines, we
