Abstract Over the last decade, perovskite solar cells (PSCs) have drawn extensive attention owing to their high power conversion efficiency (single junction: 26.1%, perovskite/silicon tandem: 33.9%) and low fabrication cost. However, short lifespan of PSCs with initial still blocks practical applications. This operational instability may originate from intrinsic extrinsic degradation materials or devices. Although lifetime has been prolonged through component, crystal, defect, interface, encapsulation engineering, so on, systematic analysis failure regularity for perspective devices against multiple operating stressors is indispensable. In this review, we start elaboration predominant pathways mechanism under working stressors. Then strategies improving long‐term durability respect fundamental materials, interface designs, device summarized. Meanwhile, key results discussed understand limitation assessing stability, potential applications in indoor photovoltaics wearable electronics are demonstrated.
