摘要

我们研究了辐照束条件对空间用硅和三结太阳能电池性能退化的影响。电子束和质子束的注量率是不同的。降解不取决于两个细胞的质子注量率。较高的电子注量率导致硅电池的更大退化,但这种依赖性是由于辐照过程中温度的升高。针对不同能量(50 keV–10 MeV)的质子辐照,研究了散焦和扫描两种光束面积扩展方法。在比较散焦和扫描质子束辐照的输出退化时,没有发现任何质子能量的退化有显著差异。我们计划将这些发现反映到空间太阳能电池辐照测试方法的ISO标准中。

Effects of Beam Conditions in Ground Irradiation Tests on Degradation of Photovoltaic Characteristics of Space Solar Cells
We investigated the effects of irradiation beam conditions on the performance degradation of silicon and triple-junction solar cells for use in space. The fluence rates of electron and proton beams were varied. Degradation did not depend on the fluence rate of protons for both cells. A higher fluence rate of electrons caused greater degradation of the Si cell, but the dependence was due to the temperature increase during irradiation. Two beam-area expansion methods, defocusing and scanning, were examined for proton irradiation of various energies (50 keV–10 MeV). In comparing the output degradation from irradiation with defocused and scanned proton beams, no significant difference in degradation was found for any proton energy. We plan to reflect these findings into ISO standard of irradiation test method of space solar cells.
