AbstractLarge-structured, high-performance spacecraft for scientific observation in space have recently been operated, so that large amount of primary power with solar cells is required to achieve their mission objectives. To resolve such a requirement, the asteroid sample return mission spacecraft, MUSES-C, which carried multijunction solar cells with a high efficiency of 26 percent and was launched at Kagoshima Space Center (KSC) in May, 2003, has paved the way for the application of the multijunction solar cells. Their widespread spectral response to the extraterrestrial sunlight, the so-called air mass zero (AM0) sunlight, can range from ultraviolet to infrared rays. In general, solar cells under development are required to withstand the AM0 sunlight during a long duration in order to be qualified as space solar cells. That's what is called aging. At their practical stage, power generation capability of solar cell panels must be evaluated by means of the AM0 sunlight after the installation of the solar cells in the panels. However, there is not a solar simulator with three kinds of lamp and the AM0 spectral characteristic for the multijunction solar cells in the world yet. It is thought that such a simulator is essential to the evaluation of future multijunction solar cells. Thus, first of all, it is described how to design a new multi-solar simulator with the three kinds of lamp: Hg lamps with high brightness in the UV region, Xe lamps in the visible region, and halogen lamps in the IR region. In its performance, it is possible to achieve an illumination intensity of 1.4 kW/sq m a projection area of 2.5 x 2.5 sq m, and a uniformity of +/- 15 percent. In addition, a spectrometer of 250 to 1,850 nm in wavelength is required to maintain a precise simulator performance specified for more than hundreds of hours.
