On-device lead sequestration for perovskite solar cells
Perovskite solar cells (PSCs) face obstacles on their way towards commercialization. Potential issues with lead toxicity and leaching from devices remain relatively unexplored. It is desirable to develop strategies that avoid potential Pb leakage to the environment, although enhanced physical encapsulation can lessen Pb leakage from devices when subjected to mild environmental damage. We present a new chemical approach for on-device sequestration (>96%) of lead leakage caused by severe device damage without sacrificing the efficiency and stability of PSCs under normal operation.
