性能决定主流选择 成本困局待破 与卓越性能相伴的，是砷化镓电池居高不下的成本。马斯克"星链"项目采用转换效率仅20%左右的晶硅 电池片，核心原因就是成本控制。"三结砷化镓太阳能电池片的转换效率普遍超30%，但成本却是晶硅 电池的数倍。"蔡坤煌表示。 ● 本报记者杨洁 商业航天大幕持续拉开，航天器的"能量心脏"——太空能源系统成为产业链竞争的关键赛道，其中砷化 镓(GaAs)太阳能电池凭借卓越性能目前占据市场主流。砷化镓太阳能电池技术在光电转换效率、极端环 境适应性上远超传统硅基电池，但也由于材料稀缺、制造工艺复杂而成本高昂。近日，中国证券报记者 走进三安光电（600703）砷化镓太阳能电池片产线一线，探寻太空能源核心技术的现状与未来。 "砷化镓是第二代半导体的代表，最显著的优势就是电子迁移率高。"三安光电砷化镓事业部总经理、天 津三安总经理蔡坤煌向记者解释，砷化镓系列材料的禁带宽度能与太阳光谱高度匹配，且作为直接带隙 材料，光子能量可直接激发电子跃迁，能量损耗远低于传统硅基电池。更关键的是，其在高低温交替变 更、强辐射的太空极端环境中能稳定运行，效率衰减慢、使用寿命长，成为航天器能源系统的首选。 作为国内较早 ...

尽管晶硅电池在太空环境中存在耐温性差、衰减快、寿命短等短板，但马斯克通过可重复火箭技术提高 卫星发射频次，尝试弥补这一缺陷。 蔡坤煌表示，航天业界正从全产业链角度系统性考量成本优化。柔性电池技术成为重要突破方向——该 技术可大幅减少航天器太阳翼的体积与重量，进而降低发射端成本。 "砷化镓是第二代半导体的代表，最显著的优势就是电子迁移率高。"三安光电砷化镓事业部总经理、天 津三安总经理蔡坤煌向记者解释，砷化镓系列材料的禁带宽度能与太阳光谱高度匹配，且作为直接带隙 材料，光子能量可直接激发电子跃迁，能量损耗远低于传统硅基电池。更关键的是，其在高低温交替变 更、强辐射的太空极端环境中能稳定运行，效率衰减慢、使用寿命长，成为航天器能源系统的首选。 作为国内较早布局砷化镓多结太阳能电池片研发与生产的企业，三安光电的技术迭代轨迹印证了行业发 展方向。2014年，公司正式推出三结锗基刚性砷化镓太阳能电池外延片，转换效率达30%；2015年实现 批量供货；2017年转换效率提升至31.5%。"2023年、2025年我们又相继研发出四结、五结刚性电池 片，转换效率进一步突破至34.5%。"蔡坤煌坦言，尽管多结技术能持续提升效率 ...
