摘要：
Among flexible photovoltaic technologies， flexible perovskite solar cells have emerged as the most attractive and promising technology because of their flexibility， low weight， low cost， and high power conversion efficiency. However， flexible perovskite solar cells have limited mechanical robustness. This issue is related to the use of rigid electrode and perovskite thin films and the large difference in the coefficient of thermal expansion between different layers. The mechanical stability of flexible perovskite solar cells must be further improved to promote the commercialization of these batteries. This paper reviewed recently published studies focusing on improving the flexibility of substrates， electrode， perovskite thin films， and interfaces. Accordingly， the main effective strategies to improve the mechanical robustness of flexible perovskite solar cells was summarized. Finally， we have briefly outlined potential development directions for highly efficient and flexible perovskite solar cells. © 2022 Chinese Academy of Sciences. All rights reserved.
