Perovskite and organic solar cells have become a hot research topic in the last few years. The lightweight thin-film solar cells are of particular interest for space applications due to their exceptional power per mass, exceeding their inorganic counterparts by magnitudes.

Here, we present the Organic and Hybrid Solar Cells In Space experiment (OHSCIS) and the launch of perovskite and organic solar cells to space for the first time [1, 2]. The mechanical and electronic design of the experiment aims at maximizing the data collection rate and precise measurements. We show that the solar cells operate in space conditions and produce reasonable power per area of up to 14 and 7 mW cm-2, respectively. Also, during a phase being turned away from the Sun, the solar cells produce power from collecting faint Sun-light scattered from Earth. Our results highlight the potential for near-Earth applications and deep space missions of these technologies.
