[Abstract] 

The power conversion efficiency of CsPbI3 perovskite quantum dot (PQD) solar cells has increased from 10.77% to 16.2% in a short period owing to advances in material and device design for solar cells. However, the device stability of CsPbI3 PQD solar cells remained poor in ambient conditions, which requires an in-depth understanding of the degradation mechanisms of CsPbI3 PQDs solar cells in terms of both inherent material properties and device characteristics. Along with this analysis, advanced strategies to overcome poor device stability must be conceived. In this review, fundamental mechanisms that cause the degradation of CsPbI3 PQD solar cells are discussed from the material property and device viewpoints. In addition, based on detailed insights into degradation mechanisms in CsPbI3 PQD solar cells, various strategies are introduced to improve the stability of CsPbI3 PQD solar cells. Finally, future perspectives and challenges are presented to achieve highly durable CsPbI3 PQD solar cells. The investigation of the degradation mechanisms and the stability enhancement strategies can pave the way for the commercialization of CsPbI3 PQD solar cells.
