Several strategies are proposed and implemented to improve the stability of perovskite solar cells (PSCs). The authors separate strategies toward stable PSCs according to the long‐term, hundreds of hours, and short‐term, minutes to hours, stability issue encountered in the operation of PSCs under standard working condition—light and load. To enhance the long‐term stability, the authors can rely on technological solutions such as encapsulation of the full device, application of hydrophobic hole selective materials, insertion of a polymer layer on top of perovskite film and enhancement of the intrinsic stability of perovskite material itself via tuning the composition. For the short‐term stability, which is mainly linked to formation and migration of ionic defects within the perovskite, bulk and interface passivation of perovskite film are demonstrated to be critically important. This article summarizes and analyzes the most recent updated strategies that are progressing PSCs toward commercialization.
