How can lead capture materials reduce lead leakage of PSCs?

In summary, integrating lead capture materials into the perovskite layer, using post-synthesis treatments, and incorporating these materials at charge transport interfaces are effective strategies for reducing lead leakage of PSCs.

How can a PSC prevent lead leakage?

Controlling lead leakage in PSCs directly mitigates lead-related health risks and environmental damage. Yet, as the perovskite photovoltaic industry expands, lead will inevitably disperse into the environment over time. Consequently, establishing robust recycling protocols throughout the lifecycle of perovskite devices becomes crucial.

Can a perovskite solar cell prevent lead leakage?

On-device lead sequestration for perovskite solar cells. Nature 578, 555–558 (2020). In this study, lead-absorbing materials with suitable transparency and lead-chelating activity at various temperatures were applied at both the front and back sides of the device stack to prevent lead leakage in a wide range of temperature conditions.

How to prevent lead leakage?

Second, the strategies of preventing lead leakages such as physical encapsulation, chemical absorption, eco-friendly perovskite materials, and recycling, are systematically analyzed.

Can superhydrophobic surfaces reduce lead leakage in perovskite solar cells?

Adv. Funct. Mater. 32, 2202408 (2022). Zhang, H. et al. Design of superhydrophobic surfaces for stable perovskite solar cells with reducing lead leakage. Adv. Energy Mater. 11, 2102281 (2021). This work reported a strategy to suppress lead leakage from PSCs by depositing superhydrophobic molecules on top of a perovskite layer.

What causes lead leakage in perovskite photovoltaic devices?

In the practical application of perovskite photovoltaic devices, lead leakage is not only caused by intrinsic material degradation but more critically from mechanical damage under extreme environmental stressors.
