How to reduce PB leakage of perovskite solar cells?

Recently, several Pb-adsorbing materials have been reported to treat the Pb-containing solutions or reduce Pb leakage of damaged perovskite solar devices 21, 22, 23. For example, a hole transport polymer of alkoxy-polytetraethylene glycol was also reported to chelate Pb ions and thus reduce Pb leakage of perovskite solar cells.

Are perovskite solar modules leaking lead?

Nature Sustainability 4, 636–643 (2021) Cite this article Lead leakage from damaged perovskite solar modules during rainfall poses a serious threat to the environment and human health. Strategies to replace lead have seen little success to date, while the encapsulation approaches tend to compromise the low-cost advantage of perovskites.

How to prevent PB leakage?

An ideal strategy to prevent Pb leakage should be able to rapidly capture Pb ions once perovskites are decomposed by rainwater and operate long term regardless of external factors such as rain, dust or UV light.
