The majority of solar panels for spacecraft and satellites are based on rigid GaAs or III-V multijunction InGaP/GaAs/Ge solar cells. These contribute significant weight to the payload system and require extensive supports made of metal alloys and bulky spring-loaded hinges for deployment [1]. For small satellites, it is not practical to increase the area of the solar panels to generate more power due to a combination of weight and size limitations. The development of a light weight, compact stowage, rollable, and self-deployable solar power generation system has the potential to increase the power output of satellites without increasing weight or launch cost. Metal halide perovskite solar cells (PSCs), an emerging technology with a power conversion efficiency (PCE) of above 25%, are anticipated to surpass current state-of-the-art photovoltaic technologies not only for terrestrial, but also for cosmic, applications. This can be attributed to their outstanding PCE, high specific power (i.e., power to weight ratio, which to a large extent determines payload weight and thus launch cost), compatibility with flexible substrates, short lead times, customisable shape, and excellent radiation resistance with self-healing ability [2-3]. These features make them appealing candidates for future space applications. CSIRO has developed high-throughput roll-to-roll printing/coating processes to produce thin, flexible, light-weight perovskite solar films based on printable ‘solar inks’. The integration of perovskite solar film with a thin rollable shape memory alloy foil that uses thermally-activated actuation for self-deployment, without hinges or a tension-loaded or motorised actuator, will be presented.
