Group 1: Satellite Launch and Development - By the end of 2025, China plans to submit approximately 203,000 satellites to the ITU, covering 14 satellite constellations, with the Radio Innovation Institute applying for two constellations, each with 96,714 satellites, totaling nearly 193,000 satellites [7][8]. - Major operators and commercial satellite companies are also advancing medium-scale constellations, with China Mobile applying for 2,520 satellites, Yuxin Satellite for 1,296, and Guodian Gaoke for 1,132 [8][10]. - As of December 2025, the overall launch completion rate for major domestic constellations remains low, indicating they are in the early stages of network formation [13]. Group 2: Starlink Program and Launch Trends - The Starlink program exhibits a clear generational rhythm, with cumulative launches reaching approximately 11,034 satellites and applications totaling about 41,943 as of January 2026 [2][16]. - The annual launch volume has increased significantly, with projections for 2025 reaching around 3,200 satellites, reflecting a trend of accelerating deployment [15][20]. - Starlink's V1 to V3 satellites utilize crystalline silicon technology to prioritize supply chain scalability and system-level cost reduction, while V4 may adopt P-type silicon HJT or P-type silicon HJT-perovskite tandem structures [3][4]. Group 3: Photovoltaic Technology in Space - The current mainstream technology for space photovoltaic applications in China is multi-junction gallium arsenide (GaAs), although there is ongoing testing and validation of perovskite systems by various companies [4][26]. - The high unit price of GaAs photovoltaic cells is becoming a significant factor limiting system economics, prompting the industry to explore lower-cost alternatives such as silicon-based and perovskite technologies [21][34]. - The article highlights the unique requirements for photovoltaic cells in space, including radiation resistance, thermal stability, and long-term reliability under extreme conditions [22][25]. Group 4: Industry Outlook and Recommendations - The acceleration of satellite launches and the continuous validation of new photovoltaic technologies indicate a rising industry outlook and long-term growth potential for the space photovoltaic sector [5][6]. - The article recommends a "buy" rating for the space photovoltaic industry, citing key companies such as Maiwei Co., Aotewi, and others as relevant investment targets [5][6].
