Core Viewpoint - The article discusses the emerging market of space photovoltaics, highlighting significant investments and developments by major companies in the sector, particularly focusing on the potential of solar energy in space applications [1][2][3]. Group 1: Market Developments - Elon Musk plans to deploy 100GW of solar AI satellites annually in space, with global photovoltaic installations expected to reach approximately 600GW by 2025 [1][2]. - Major players in the photovoltaic industry, such as JinkoSolar and Trina Solar, are exploring opportunities in space photovoltaics, indicating a growing interest in this market [2]. Group 2: Technical Advantages - Space photovoltaics utilize solar panels on satellites, benefiting from abundant sunlight in space, with average power generation being 7 to 10 times higher than on Earth [4]. - Satellites can achieve significant power outputs, with some reaching up to 100kW, necessitating advanced photovoltaic technologies [4]. Group 3: Current Technologies - Gallium arsenide (GaAs) is currently the primary material used in space photovoltaics, offering a conversion efficiency exceeding 30% due to its superior light absorption capabilities [5]. - The cost of space photovoltaic panels is significantly higher, potentially reaching 1000 RMB/W, compared to less than 1 RMB/W for ground-based solar power [5]. Group 4: Future Innovations - Perovskite solar cells are emerging as a next-generation technology, with theoretical efficiencies up to 45%, and their lightweight nature could reduce satellite launch costs significantly [7]. - Trina Solar has secured exclusive licensing agreements for perovskite technology, indicating a strategic move towards this innovative material [7]. Group 5: Challenges and Testing - The stability of perovskite materials remains a challenge, particularly in the harsh conditions of space, but initial tests have shown promising results with minimal efficiency loss [8]. - Future tests are planned to further validate the performance of perovskite components in extreme space environments [8].

一周时间内，两位光伏大佬相继锁定太空光伏赛道。 12月26日，晶科能源董事长李仙德发表2026年新年致辞，提出晶科能源应探索太空光伏的市场机会。 12月30日，天合光能董事长高纪凡在2026年新年致辞中提出:"新的一年，天合光能将加快推进钙钛矿量产化商业化进程，开启太空光伏星际算力新纪元"。 高纪凡亦将太空光伏列为2026年的第一个发展方向。 光因科技联合创始人、首席运营官刘伟俊向记者表示，太空光伏成为卫星供能的首选，主要有两大原因。 首先是太空光照资源丰富，近地轨道卫星可实现90分钟绕地球一圈，日照占比超过60%，地球同步轨道卫星仅在春分、秋分时节无法发电，而且外太空避免 了大气层的干扰，每平方米光照强度比地球高30%以上；其次是配套设施简便，在卫星上部署光伏组件，无需光伏玻璃、支架、冷却系统等，仅需提高光伏 组件自身的发电效率及可靠性。 李仙德在新年致辞中表示：同等组件在太空的平均发电量是地球上的7倍至10倍，是实现太空算力、深空探测等全宇宙场景唯一可行的长效能源支撑，是解 决未来地球AI电力短缺和实现"太空发电—无线传输—地面接收"的全链条新型能源方案。 当前太空光伏主要使用砷化镓产品。天合光能研发负责 ...
