Abstract:
Perovskite solar cells (PSCs) have surpassed 27% power conversion efficiency, yet long-term stability and scalable manufacturing remain key barriers to commercialization. Carbon nanotubes (CNTs), graphene, and their derivatives offer promising solutions owing to their excellent electrical, optical, and mechanical properties. This review highlights their applications in PSC electrodes, charge-transport layers, and interfaces, focusing on charge extraction, interface engineering, and device stability. Key challenges, including film uniformity, reproducibility, and large-area fabrication, are also discussed, along with strategies for developing efficient, durable, and scalable carbon-based PSCs.
