SpaceX, a US-based aerospace and satellite technology company, has engaged seven Chinese HJT enterprises in early 2026. The engagement has focused on sourcing lightweight and radiation-resistant space PV modules for its orbital data center satellite program. Traditional space PV systems rely on gallium arsenide materials costing 200000 to 300000 RMB per square meter. This cost structure has limited large-scale satellite energy deployment. HJT cells with thickness below 50 microns and high radiation resistance are being evaluated as alternatives. Adoption of HJT technology has the potential to reduce component costs by over 60%. Maiwei Corporation has received a 7 GW trial production line order from SpaceX. Dongfang Risheng has confirmed monthly supply exceeding 100000 p-type ultra-thin HJT cells from 2026. Junda Corporation expects its HJT production capacity to exceed 60 GW by 2026.
