Lead – An Obstacle for Installing Perovskite Devices?

As the commercialization of perovskite solar cells is approaching, environmental issues, such as the environmental burden of Pb, have gained attentions. The first thing to be considered is the leakage of Pb-contained substances once the perovskite solar cell device is damaged due to natural disasters or unforeseeable accidents. Therefore, according to the existing survey data and life cycle assessment, an objective analysis of the environmental hazards caused by Pb leakage is carried out. Although the results show that the benefits do outweigh the risks, we still believe that it is necessary to make breakthroughs in appropriate perovskite materials, advanced encapsulation technologies, and complete disposal solutions.
