Furthermore, the instability of perovskite materials can cause problems like hysteresis, or variations in the solar cell's output voltage, and lower PCE . In this section, we will review the several factors that affect the stability of PSCs. Moisture intrusion is a significant challenge that can lead to the degradation of PSCs.
The temperature of the working environment has a strong influence on the stability and performance of the perovskite layer. For example, the band gap, surface tension, charge diffusion, and recombination process will adjust with the temperature change .
Chemical nature The chemical stability of a perovskite structure under different environmental conditions plays vital role in determining the durability and sustainability to the perovskite-based devices (Niu et al., 2015, Poorkazem and Kelly, 2017, Kundu and Kelly, 2018, Niu et al., 2014, Letcher and Fthenakis, 2018).
Despite being a persistent problem in perovskite PV, stability has improved by orders of magnitude in the first decade of mainstream perovskite PV research. With the introduction of various stability-enhancing methods, the operational stability of PSCs is maturing beyond practically achievable testing lifetimes.
Moreover, perovskites can be a potential material for the electrolytes to improve the stability of batteries. Additionally, with an aim towards a sustainable future, lead-free perovskites have also emerged as an important material for battery applications as seen above.
