Enhancing Perovskite Solar Cell Durability: innovative waterproofing using PTFE and PVDE polymer materials simultaneously

Mehran Hosseinzadeh Dizaj1

Abstract :
Weather can have detrimental effects on perovskite materials, primarily through moisture infiltration, leading to degradation of the perovskite structure and reduced device performance. Humidity can induce the formation of hydrates or perovskite decomposition products, causing irreversible damage to the material. Additionally, exposure to ultraviolet (UV) radiation and temperature fluctuations can accelerate degradation processes, compromising the stability and efficiency of perovskite-based devices. The penetration of moisture can significantly reduce the efficiency and stability of perovskite solar cells. Research suggests that even a small amount of moisture ingress can lead to a considerable decrease in efficiency, with reductions ranging from 10% to 90%, depending on the severity of the moisture exposure. Additionally, moisture-induced degradation can substantially compromise the stability of perovskite materials, leading to accelerated aging and structural deterioration, which can further exacerbate efficiency losses over time. Polytetrafluoroethylene (PTFE) and polyvinylidene fluoride (PVDF) are both fluorinated polymers known for their excellent chemical and thermal stability, as well as their hydrophobic properties. When used as encapsulation materials for perovskite solar cells, PTFE and PVDF can effectively increase the lifespan of perovskite materials by providing a protective barrier against environmental factors such as moisture, oxygen, and UV radiation[1], [2], [3].
