Global GaAs Space Market Data

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. In 2026, the global multi-junction GaAs space photovoltaic market is expected to reach approximately US$979.6 million, up 15% year over year; the average selling price of space-grade triple-junction (3J) GaAs cells is about US$307 per watt, corresponding to an annual cell capacity of roughly 48 MW. For the space GaAs segment specifically, the market is projected to grow from US$645.5 million in 2025 to US$1.16 million by 2032, implying a CAGR of 8.8%. The broader multi-junction arsenide market is expected to expand from US$851.7 million in 2025 to US$2.01 million in 2032, at a CAGR of 13.0%.
