Metal halide perovskite solar cells (PSCs) are of interest for high altitude and space applications due to their lightweight and versatile form factor. However, their resilience toward the particle spectrum encountered in space is still of concern. For space cells, the effect of these particles is condensed into an equivalent 1 MeV electron fluence. The effect of high doses of 1 MeV e‐beam radiation up to an accumulated fluence to 1016 e− cm−2 on methylammonium lead iodide perovskite thin films and solar cells is probed. By using substrate and encapsulation materials that are stable under the high energy e‐beam radiation, its net effect on the perovskite film and solar cells can be studied. The quartz substrate‐based PSCs are stable under the high doses of 1 MeV e‐beam irradiation. Time‐resolved microwave conductivity analysis on pristine and irradiated films indicates that there is a small reduction in the charge carrier diffusion length upon irradiation. Nevertheless, this diffusion length remains larger than the perovskite film thickness used in the solar cells, even for the highest accumulated fluence of 1016 e− cm−2. This demonstrates that PSCs are promising candidates for space applications.

钙钛矿太阳能电池：在太空条件下稳定
金属卤化物钙钛矿太阳能电池（PSC）的重量轻，用途广泛，是高海拔和太空应用的关注点。然而，它们对空间中遇到的粒子光谱的弹性仍然值得关注。对于空间电池，这些粒子的作用被浓缩为等效的1 MeV电子注量。大剂量1 MeV电子束辐射的影响，直至累积通量达到10 16 e - cm -2在甲基铵碘化铅钙钛矿薄膜和太阳能电池上进行了探测。通过使用在高能电子束辐射下稳定的基板和封装材料，可以研究其对钙钛矿薄膜和太阳能电池的净效应。基于石英衬底的PSC在高剂量1 MeV电子束辐照下是稳定的。对原始膜和辐照膜进行时间分辨的微波电导率分析表明，辐照后载流子扩散长度略有减少。然而，即使对于最高累积能量密度为10 16 e - cm -2，该扩散长度仍然大于太阳能电池中使用的钙钛矿膜的厚度。这表明PSC是有希望的航天应用候选产品。
