The lack of theoretical studies about the structure and storage properties of different perovskite materials are also the limitations for understanding the charge storage mechanisms. So, there is still a lot more to do to enhance the electrochemical performance of the perovskite materials for the future applications.

If the selective contact follows the Fermi level of the perovskite and is influenced by the perovskite layer, they should not be treated as a mere series of connected systems but as parallel interrelated layers, a fact that could influence, for example, future impedance models of the device. Further research and experiments will be needed to
Perovskite solar cells (PSCs) have a higher power conversion efficiency compared with established PVs. Nevertheless, the most efficient PSCs are made from lead halide salts (PbI2 and PbBr 2) and, thus, are potentially toxic. Consider the potential extensive application of PSCs over the next 20–30 years.
Lead-based perovskites are emerging as a new material for the next generation of solar cells for large-scale energy production. Here, we provide our perspective on commercializing solar cells based on perovskites containing lead.
In addition, Pb-based perovskite solar cells have poor stability and easily deteriorate in the air. According to the research by Wang and co-workers, the moisture stability of Pb-based PSCs is about 2000 h (humidity = 45%). (3) Therefore, many wasted PSCs were discarded as waste after invalidation.
The team's work clearly demonstrates that lead recovered from old batteries is just as good for the production of perovskite solar cells as freshly produced metal. Some companies are already gearing up for commercial production of perovskite photovoltaic panels, which could otherwise require new sources of lead.
The Authors, published from 2020 Springer Nature. Therefore, lead-based perovskites pose significant risks to animal and human health as well as ecosystem. These toxic effects of perovskites are mainly caused by the released Pb 2+ ions with toxicity proved to be higher than their individual degradation products PbI 2 and PbO.
