柔性、薄膜和高效III-V太阳能电池的开发使得能够设计用于空间应用的新型柔性、轻质太阳能电池阵列。对这些太阳能电池板的要求是用柔性屏蔽层代替刚性覆盖玻璃。在这项工作中，三个候选材料的基础上，商业上可获得的聚酰亚胺和合成的聚硅氧烷这样的屏蔽层进行了比较，其易于合成，透明度。基于甲基三甲氧基硅烷（MTMS）基硅氧烷（MBS）的聚硅氧烷在合成具有足够透明度的约300 μ m所需厚度的层时显示出最佳再现性，因此被选择用于进一步分析。结果表明，在MBS材料中掺杂Ce可以提高材料的抗辐射性能。在除气试验中几乎没有挥发性可冷凝组分的损失，因此可以得出结论，MBS的性能适合于进一步的空间鉴定试验。(c)2016 Wiley Periodicals，Inc.

The development of flexible, thin-film, and high-efficiency III-V solar cells enables the design of new flexible, lightweight solar arrays for space applications. A requirement for these solar panels is the replacement of the rigid coverglasses by a flexible shielding layer. In this work, three candidate materials based on commercially available polyimides and synthesized polysiloxanes for such a shielding layer are compared with respect to their ease of synthesis, transparency. Polysiloxanes based on methyltrimethoxysilane (MTMS) based siloxane (MBS) showed the best reproducibility in synthesis of layers of the required thickness of about 300 mu m with sufficient transparency and was therefore selected for further analysis. It was demonstrated that the MBS material could be doped with Ce to increase the radiation hardness. Showing virtually no loss of volatile condensable components in outgassing tests it can be concluded that the properties MBS are found suitable for further space qualification testing.
