The increasing efficiency of perovskite solar cells (PSCs), driven by their low cost, low carbon footprint and easy processability, offers real opportunities for new markets in innovative photovoltaic (PV) technology. A crucial challenge in this transition is device instability. Carbon-based perovskite solar cells offer a promising alternative with the advantages of more abundant materials and stable performance. This review provides a comprehensive and critical analysis of recent advancements in carbon-based PSCs (C-PSCs) technology, focusing on the applications of carbon electrodes and their critical role as interfacial electrodes, as well as discussing the advantage of this configuration in terms of deposition methods for large-area modules. Furthermore, techno-economic aspects will be considered to provide an assessment of the suitability of C-PSCs for applications ranging from large-area PVs to indoor applications and flexible electronics.
