Environmental lead exposure from halide perovskites in solar cells

Lead (Pb) is one of the most toxic elements in existence and has been used by humans for thousands of years. With only a few exceptions, each widespread application of lead has been banned systematically due to dramatic environmental and health consequences. However, we are now at the dawn of the perovskite era, potentially requiring yet again the widespread application of lead.

Automated summary

Lead, known as one of the most toxic elements, has been prohibited due to its severe environmental and health impacts. However, as we enter the perovskite era, the widespread application of lead may be necessary once again.
