国盛证券：低轨星座竞赛与太空算力革命 引爆太空光伏需求新周期

Group 1 - The rapid increase in satellite deployment and the planning of space AI computing power are driving exponential growth in demand for space photovoltaic systems, which are transitioning from supporting components to strategic infrastructure [1] - China plans to submit applications for 203,000 satellites by the end of December 2025, while the US has launched over 10,000 satellites under the SpaceX Starlink program, intensifying the global space race [1] - The emergence of "space-based data centers" is driven by the limitations of ground data centers, with space offering continuous sunlight and near-zero cost cooling due to the cold cosmic background [1] Group 2 - New technological pathways are emerging, including P-type HJT batteries and silicon/perovskite tandem cells, which offer lower costs and improved performance compared to traditional gallium arsenide batteries [2] - P-type HJT batteries benefit from lower costs due to their manufacturing process and established supply chains, while silicon/perovskite tandem cells have demonstrated laboratory efficiencies of around 35% [2] - Perovskite materials are seen as the ultimate solution for space photovoltaics due to their high defect tolerance and radiation resistance, making them suitable for the harsh conditions of space [2] Group 3 - The global manufacturing landscape is misaligned, presenting historic opportunities for Chinese equipment and battery manufacturers as the US lacks capabilities in HJT and perovskite production lines [3] - The demand for photovoltaic equipment is expected to surge as SpaceX and Tesla plan to build a total of 200 GW of photovoltaic capacity in the US over the next three years [3] - Chinese photovoltaic companies, equipped with aerospace certification and large-scale delivery capabilities, are transitioning from ground support to core space applications, positioning themselves to benefit from the growing demand for space photovoltaics [3] Group 4 - Investment recommendations include photovoltaic equipment suppliers such as Maiwei Co., and potential players like Laplace, Liancheng CNC, Jiejia Weichuang, Aotwei, Gaocai Co., Dier Laser, and Jingsheng Mechanical & Electrical [4] - Material suppliers recommended include Junda Co., Dongfang Risheng, Mingyang Smart Energy, Shanghai Port, Qianzhao Optoelectronics, Trina Solar, and Shuangliang Energy [4]
