Abstract
Abstract Flexible perovskite solar cells (F‐PSCs) have attracted extensive research attention due to their high power‐to‐weight ratios, low cost, and scalable production, as well as their potential applications in self‐powered wearable devices, space photovoltaics, and the Internet of Things. The power conversion efficiency (PCE) of F‐PSCs has increased remarkably to 25.44%, and their mechanical and environmental stability have also been substantially enhanced through advancements in the development of novel materials for each functional layer and interface, as well as the refinement of fabrication techniques. This review provides a systematic overview of recent progress in novel materials for obtaining high‐quality functional layers and effective strategies for optimizing the interface between the charge‐transport layer and the perovskite. The fabrication techniques from the laboratory to industrial production, as well as the potential applications of F‐PSCs, are also discussed. Finally, the future prospects for the further development of F‐PSCs are outlined, including the development of novel materials, the advancement of fabrication techniques, and the realization of commercial applications.
