When the solar cell panels especially perovskite solar cells are damaged, lead would possibly leak into the surrounding environment, causing air, soil and groundwater contamination.
At very serious condition where the simulated heavy rain lasted for 72 h, lead in perovskite films entirely leached out with the leaking amounts of 0.54 g/m 2 for the damaged PSCs both without encapsulation and with only the bottom glass encapsulation (Jiang et al., 2019).
In addition to the physical fail-safe encapsulation to prevent lead leakage, there are some chemical approaches by designing hole transport layer (HTL), electron transport layer (ETL) and electrodes with lead-absorbing ability, or introducing additional lead-sequestrating materials into the PSC device structure.
In general, lead in PSCs would leach from damaged encapsulation at three stages throughout their entire lifetime: (1) panel production, (2) panel use in midlife, and (3) end-of-life disposal of PSCs. Among three stages, the lead leakage mechanism and solutions in midlife and end-of-life stages will be the focus on our discussion.
Herein, we succeed in mitigating Pb leakage of PSCs, for the first time, via implanting in situ polymerized networks into perovskites. We strategically transform the dormant monomer additives into chelating polymer networks within perovskite layers, which not only passivate the defects of perovskite but also protect Pb 2+ from water dissolution.
We are deeply committed to excellence in all our endeavors.
Since we maintain control over our products, our customers can be assured of nothing but the best quality at all times.
