MUNICH, Germany (DLR PR) — Almost all satellites are powered by solar cells – but solar cells are heavy. While conventional high-performance cells reach up to three watts of electricity per gram, perovskite and organic hybrid cells could provide up to 10 times that amount.

A research team from the Technical University of Munich (TUM) and the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) has now tested this type of cell in space for the first time.
