谁是太空算力的“天选之子”？丨每日研选

Core Insights - The commercial aerospace sector is becoming a focal point in the A-share market, driven by the transition of "space computing" from science fiction to commercial deployment [1] - The demand for space photovoltaics is experiencing a historic opportunity due to revolutionary breakthroughs in downstream application scenarios, particularly in the on-orbit data center market, projected to reach $39.09 billion by 2035 with a compound annual growth rate of 67.4% [1] - The unique requirements of computing satellites are reshaping the technology route for space photovoltaics, moving towards low-cost, lightweight, and high-efficiency silicon-based technologies [1] Group 1: Technology and Market Trends - Heterojunction (HJT) batteries are expected to lead in the short to medium term due to their low-temperature processing, compatibility with ultra-thin silicon wafers, and flexible characteristics [2] - P-type ultra-thin HJT batteries can significantly reduce launch payloads and costs while adapting to the new "foldable" solar wing structures, which are the mainstream direction for low Earth orbit satellites [2] - The next-generation technology represented by perovskite is seen as a long-term game-changer, although it requires more time to mature [2] Group 2: Investment Opportunities - Investment strategies should focus on three main lines: 1. Core suppliers of the current dominant technology, gallium arsenide, such as Qianzhao Optoelectronics and Sanan Optoelectronics [2] 2. Companies actively developing P-type HJT and next-generation perovskite technologies, including Dongfang Risheng, GCL-Poly, and Junda Co., along with leading equipment manufacturers like Maiwei and Jiejia Weichuang [2] 3. Opportunities across the entire supply chain benefiting from the expansion of space scenarios, including special functional materials and high-end components [3]
