Stability of perovskite active layers induced by caffeine: A mini review

20241 citationOpen accessUniversity of South Africa

Abstract

Perovskite materials because of its advantageous qualities, offers significant deals of potential for increasing the efficiency of perovskite solar cells (PSCs). Notwithstanding these characteristics, perovskite solar cells' efficiency is still constrained by the instability problem, which is currently up for debate. The variables influencing the stability of perovskite materials are covered in this review. The primary goal is to provide some insight into caffeine's role as an enhancer of perovskites solar cells' performance and thermal stability. Using such layers of caffeine has been shown to increase the efficiency of PSCs, since it enhances stability, crystallinity, and overall efficiency. Nonetheless, it is crucial to take into account the caffeine material's affordability, processing strategy, stability, and deposition approach scalability. However, there are a lot of gaps in the caffeine layer that is frequently employed in PSCs with higher conversion efficiency. Consequently, the primary goal is to learn about the characteristics of caffeine on its own before combining it with perovskites. Additionally, employing various perovskites materials, guarantee the long-term stability and dependability of perovskite solar cells with caffeine layer under actual operational situations, such as exposure to moisture, temperature fluctuations, and UV radiation.
