Abstract: The traditional standard solar cell calibration methods are divided into high-altitude calibration and ground calibration,and the ground calibration method has been included in the ISO.Ground calibration is widely used nowadays because it is easy to operate and the calibration results are relatively accurate.Whether the results of solar cell calibration are accurate or not is of great significance to the design of the spacecraft power system attitude sensitive period and ground environment simulation.The ground calibration method of solar cells is discussed in this paper,a portable and high accuracy ground calibration test equipment is developed,based on the theories of ground calibration method in the national standard,including collimation holes,solar cell tray,solar tracker,and other calibration devices,to simplify the ground calibration process,which is of great significance to the ground calibration of aerospace solar cells.

Key words: Solar cell calibration technology, Ground calibration method, Short-circuit current, Value transfer
