Front‐Edge Research Progress of Photo‐Rechargeable Perovskite Solar Cell‐Zinc‐Ion Batteries

Abstract

Abstract With the rapid development of the new generation of self‐powered pocket electronic devices, the demand for sustainable and self‐sufficient power sources has become increasingly critical. Photo‐rechargeable batteries, as an efficient energy‐saving alternative to traditional energy sources, offer substantial societal benefits in modern life. Rechargeable zinc‐ion batteries integrated with perovskite solar cells (PSC‐ZIBs), characterized by both high outdoor and indoor efficiencies, light‐weight, and non‐flammability properties, hold great promise for applications in wearable devices, indoor photovoltaics, energy recycling, and other fields. This review comprehensively summarizes the development of PSC‐ZIBs. A meticulous discussion is presented regarding its mechanism and front‐edge development, such as the structural optimization and performance improvement of PSC‐ZIBs hybrid systems. Special emphasis is placed on the application prospects of Internet of Things (IoT) devices and indoor photovoltaic scenarios, which benefit from the PSC and ZIB units. Finally, perspectives, critical insight, and recommendations for future research are provided, aiming to facilitate the development of high‐performance PSC‐ZIBs devices and promote their practical implementation.
