摘要：

We provide a review of current understandings of mechanical properties and fracture behaviors of perovskites that are essential for flexible and stretchable solar cell (SC) applications. We first review the mechanical failure modes in perovskites. We further discuss the underlying mechanisms of mechanical failure and its impact on device degradation in flexible perovskite solar cells (PSCs). Then, we examine the strategies to mitigate these mechanical issues in flexible PSCs. Lastly, we assess the elevated challenges and present recommendations for future research directions to advance the technology towards a fully stretchable and wearable energy source.
