Perovskite and organic solar cells possess a revolutionary potential for space applications. The thin-film technologies enable an exceptional power per mass, exceeding herein their inorganic counterparts by magnitudes. However, research was mainly restricted to terrestrial conditions so far. We report the launch of two types of perovskite and organic solar cells on a suborbital rocket flight, possibly the first in-situ demonstration of these technologies in space conditions [1]. Both, planar and mesoscopic nip-type perovskite solar cell types exceeded an power per area of 14 mW cm-2, whereas both bulk heterojunction absorber PBDB-T:ITIC and PTB7-Th:PC71BM organic solar cell types reached more than 4 and 7 mW cm-2, respectively. Our results highlight both the suitability for near-Earth applications and the potential for deep space missions of these technologies. [1] L.
