Study of solar simulator calibration method and round robin calibration plan of primary standard solar cell for space use

The electrical characteristics of solar cells for space use had been calibrated by European and American calibration facilities. These calibration facilities have been giving satisfactory results for a primary standard of solar cell for space and terrestrial use, and are recognized in the world. The authors have compared the short circuit current of standard solar cells calibrated by balloon flight and space shuttle methods with those calibrated by the JQA solar simulator method. The results showed almost equivalent values. Therefore, the authors believe that the JQA solar simulator method is an effective calibration method together with balloon flight, aircraft and space shuttle methods. In this paper, the authors introduce the JQA solar simulator method and the round-robin calibration plan of a primary standard solar cell for space power use.
