By analysing lead-based perovskite solar cells with different architectures in a cradle-to-gate LCA approach, different groups 13–15 came to the same conclusion: lead is not the main concern in terms of toxicity or environmental impact.
Despite notable advantages and power conversion efficiency achieved by perovskite solar cells (PSCs), they could not hit the market commercially as perovskite solar cells are bottlenecked by the toxicity issue caused by the metal lead. Lead has proven toxicity issues that can harm human beings and the ecological system to a significant extent.
Lead-based perovskite materials have drawn the attention of researchers around the globe. These cells have the potential to improve the efficiency of solar energy conversion, and they are being developed as a replacement for traditional solar cells (SCs).
On-device lead sequestration for perovskite solar cells. Nature 578, 555–558 (2020). In this study, lead-absorbing materials with suitable transparency and lead-chelating activity at various temperatures were applied at both the front and back sides of the device stack to prevent lead leakage in a wide range of temperature conditions.
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.
