太阳电池空间标定技术初探

随着各种新型空间太阳电池的发展和应用,在地面使用太阳模拟器对AMO标准太阳电池进行标定的方法在理论和实践上都遇到了严重的困难,最能反映其实际使用状态的空间标定成为解决问题的理想方案。国外太阳电池空间标定技术已十分成熟,主要航天国家如美国、欧洲、日本、巴西等都进行了各自的空间标定实验。北京东方计量测试研究所进行了太阳电池空间标定原理样机的研制工作。样机由太阳电池板、数据采集与处理模块、太阳敏感器和温度传感器组成,可同时对32路国产砷化镓多结太阳电池进行短路电流的测量,电流测试的标准不确定度小于0.5%(最佳点)。此项研究将形成标准太阳电池空间标定的完整方案,促进我国新型空间太阳电池的研究和应用。

Primary Investigation of the AMO Solar Cell Space Calibration

With the development of new solar cells for spacecraft,the calibration and test system of which is much more complicated than the single junction silicon cells,and the ground based calibration technique has met lots of difficulties,not only in theory but in practice.Space calibration,which is in the actual working state of the solar cells,becomes the best way to evaluate their performance.Beijing orient institute of measurement has taken action of development of AMO solar cell space calibration prototype.The Prototype is made up of the solar cell panel,the data acquisition module,the solar incident angle detector and the temperature measurement module.The program will form a complete scheme of the AMO solar cell space calibration,and make efforts to the development of new space solar cells of China.
