Addressing the stability issue of perovskite solar cells for commercial applications |
| 초록 |
Despite high power conversion efficiency, poor operational stability of perovskite solar cells (PSCs) remains as a critical hurdle toward commercialization. The operational instability of PSCs mainly stems from high density of charged defects and its migration under potential gradient. Here, I will introduce our approaches to mitigate detrimental effects of the defects. I will first report methodologies for controlling crystal growth of perovskite thin films to suppress formation of the defects. Correlations between molecular interactions and crystal growth kinetics will be discussed. Secondly, the mechanism and possible side effects of commonly used defect passivation strategy will be elucidated. We identified that surplus passivation agents can induce unintended defects, which seriously degrade performance and stability of the PSCs. Finally, we propose a possible solution for minimizing the side effects to maximize attainable performance and stability. |
