This review paper explores the properties of graphene-based transparent electrodes for space solar cell applications. The space environment is extreme due to high-energy radiation, high vacuum and alternating temperature, which are responsible for damaging the atomic structure of materials, and so it influences the performance of a device. In this context, using a physical description of graphene, we analyze its electrical and optical properties, like transmittance and sheet resistance, in order to obtain innovative transparent electrodes that can perform in extreme conditions. In this sense, graphene can be a good candidate for this kind of application.
