This review focuses on the development of lead-free non-toxic perovskite materials based solar cells and other devices. To solve the lead associated toxicity problem, lead can be substituted with nontoxic and environmentally friendly metals like Ti, Sn, Sb, Ge, Bi, and Ag.
Lead-based halide perovskite solar cells have toxicity issues that hinder their large-scale commercial applications. The toxicity of these materials hinders their use. However, a variety of non- or low-toxic perovskite materials have been used for the development of environmentally friendly lead-free perovskite solar cells. Some of these materials show excellent optoelectronic properties and device performances.
Lead-free perovskite materials like Sn, Ge, Sb, Bi, their combinations, and other perovskite materials such as double perovskites are being explored for photovoltaic SC fabrication. Their advantages, stability, and technical issues are discussed in this review.
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).
