耀看光伏第12期——太空光伏四问四答

Investment Rating - The report maintains a "Positive" investment rating for the industry [10] Core Insights - Space photovoltaic technology plays an irreplaceable role in large low-orbit satellite constellations, space computing, and space power transmission, making it a core technology for major countries' space strategies. The mainstream technology currently is gallium arsenide multi-junction batteries, with potential for silicon batteries to regain prominence due to cost reductions and efficiency improvements. Perovskite technology is also expected to emerge as a strong contender [2][6][41]. Summary by Sections Why Develop the Space Photovoltaic Industry? - Space has become a new battleground for major powers, with countries actively planning space development and enhancing their capabilities. Space photovoltaic technology is the preferred energy source for spacecraft, providing reliable energy during missions. The demand for photovoltaic batteries is expected to grow rapidly due to the construction of large low-orbit satellite constellations driven by military, communication, political, and commercial needs [5][15][17]. What Technology Routes are Chosen for Space Photovoltaics? - The energy generation part of spacecraft power systems includes photovoltaic, chemical batteries, and nuclear reactors. For long-duration missions, photovoltaic systems are the preferred choice. Current mainstream technology is gallium arsenide multi-junction batteries, which have an in-orbit efficiency exceeding 30%. Silicon batteries may regain prominence due to cost and efficiency improvements, while perovskite technology meets the demands for high efficiency, lightweight, low cost, and flexibility [6][33][35][41]. What is the Market Space for Space Photovoltaics? - The global gallium arsenide battery market is expected to reach approximately 3 billion in 2023, driven by the deployment of large low-orbit constellations. By 2030, the space photovoltaic market corresponding to low-orbit satellites is projected to be around 29.5 billion, approximately ten times the current market size. The space computing sector will further expand market opportunities, with optimistic, neutral, and pessimistic scenarios predicting market sizes of 2.38 trillion, 1.33 trillion, and 280 billion, respectively [7][56][59]. Which Companies are Engaging in the Space Photovoltaic Field? - Companies focusing on space perovskite technology are recommended for short-term investment, while those with established ground perovskite technology making inroads into space applications should be monitored for long-term potential. Strategic partnerships, such as that between Junda Co. and Shangyi Optoelectronics, aim to establish leadership in space photovoltaic technology. Companies with HJT technology that have product samples and production capacity in the U.S. are also of interest [8][67][72].
