Abstract

The main objective of this study was to enhance the quality of slot-die-processed perovskite film layer using an additive process that could improve the performance and stability of perovskite devices. To improve slot-die-processed perovskite, 2-hydroxyethyl acrylate (HEA) additive with -OH was utilized as an effective functional group. The addition of HEA controlled the perovskite's growth, enlarged perovskite's grain size, and reduced perovskite's defects. As a result, the slot-die-processed device fabricated with HEA as additive produced a high efficiency of 16.08% and a good stability, maintaining an initial efficiency of 80% under air for 95 days.
