Thin-film perovskite and organic solar cells exhibit an exceptional power per mass that makes them particularly interesting for space applications. Recently, we launched perovskite and organic solar cells into space on a suborbital rocket flight for the first time [1, 2]. The rocket experiment enables post-flight characterization of the space-probed solar cells, based on Grazing-Incidence Small-Angle and Wide-Angle X-ray Scattering (GISAXS/GIWAXS) to investigate morphological and structural changes in the active layers. The morphology is altered slightly by the space flight and environmental conditions before and after the rocket launch; interestingly, the sole solar cell transport in nitrogen environment modified their active layers compared to the reference solar cells. The crystalline phase, however, does not reveal changes in any solar cell type. [1] L. Reb et al., Joule 4,1880-1892 (2020), doi.org/10.1016/j.joule.2020.07.004. [2] L. Reb et al., Rev. Sci.
