Abstract

Metal halide perovskite solar cells (PSCs) have exhibited colossal potential for future photovoltaic applications due to their favorable properties. Instability towards moisture has been their primary concern, which reduces their lifetime during prolonged periods. Herein, we demonstrate an ambient hermetic encapsulation process to eradicate the moisture penetration into the PSCs based on the profound understanding of the degradation. The encapsulation of the PSCs was performed on a glass slide with a hermetic seal using ultraviolet (UV) curable glue. The devices were kept outside with ISOS D1 protocol showed excellent behavior with degradation 10 when compared to unencapsulated devices, which were prone to more than 60 degradation. Besides, the solar cells were immersed in water to observe the penetration of water molecules. The PSCs encapsulated showed no change for 48 hours, whereas the unencapsulated devices changed their color within 2 minutes, showing a pathway for an efficient encapsulation process for scalable and robust perovskite solar cells. © 2021 IEEE.
