Multi-junction gallium arsenide (MJ-GaAs) space solar cells, with high conversion efficiency, excellent radiation resistance, and strong performance under high-temperature and high-vacuum conditions, remain the mainstream power solution for LEO/GEO satellites, deep-space probes, and similar missions
Bio-inspired robots are formed by the integration of biological and electromechanical systems at the molecular, cellular and tissue levels. They possess unique advantages such as high energy efficiency, self-growth, self-repair and biocompatibility, and represent a rapidly developing frontier field in recent years.In terms of wireless propulsion, the research team constructed an integrated propulsion architecture comprising ‘near-infrared laser – photoelectric conversion – neural electrical stimulation’. Gallium arsenide (GaAs) photovoltaic modules are integrated onto the robot’s back; by irradiating the left and right photovoltaic modules with laser light in a time-division and zone-division manner, the sequencing of bilateral muscle contractions can be independently controlled。
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, 2. Push “Large” to the Limit and Press Down “Soft Costs”
