An analysis of chemical processes to immobilize lead from perovskite solar cells is presented, highlighting the need for a standard lead-leakage test and mathematical model to reliably evaluate the potential environmental risk of perovskite optoelectronics.
Lead-free perovskites offer a potential avenue to circumvent the issue of toxicity and environmental impact of lead in perovskites. Despite their outstanding performances, the presence of lead in perovskites is a severe concern for their future commercialisation due to these risks.
However, the actual environmental impact of lead from perovskite is unknown. Here we show that the lead from perovskite leaking into the ground can enter plants, and consequently the food cycle, ten times more effectively than other lead contaminants already present as the result of the human activities.
At the interface between the perovskite solar cell and the LIB, an electrolyte or electrolyte medium is present, allowing the migration of lithium ions. During the charging and discharging process, this lithiation alters the perovskite, as the Li + embeds itself in the interlayer spacing between the octahedrons and [PbI 6] 4−.
Because of the high toxicity associated with lead, it seems a pressing need to clean and remove toxic lead from currently available and future inorganic Perovskite solar cells. Environmental-health hazards are posed by lead-based compounds and devices available for use.
