Hybrid Perovskite (HP) semiconductors have been skyrocketing the field of new generation photovoltaics and expanding into advanced optoelectronics. Perovskite photovoltaics (PV) can give a tremendous push to the green energy transition, which calls for efficient, low cost, but also environmentally friendly solutions. Halide perovskites present a serious drawback related to the presence of toxic materials, i.e., lead, with its associated health and environment concerns. These concerns severely hamper their commercialization. So far, only a few viable alternatives to Pb have been found, which lag behind in terms of power conversion efficiency. Here, a forward‐looking perspective is developed presenting different potential strategies to overcome the environmental and health issues related to the use and release of lead for operative HP solar cells. The possible lead‐leakage paths and related “remediation” tools are reviewed, and possible strategies are collated with a view to beginning a new era of lead containing HP devices. Finally, through a comparison with existing lead‐based technology, a comparative study is presented to provide the tools that are essential for a real evaluation of the impact of lead content on HP commercialization.

与混合钙钛矿中的铅打交道：为解决这项技术的光明未来而面临的挑战？
混合钙钛矿（HP）半导体一直在推动新一代光伏技术的发展，并向先进的光电技术发展。钙钛矿光伏（PV）可以极大地推动绿色能源转型，这需要高效，低成本且环保的解决方案。卤化钙钛矿存在严重的缺陷，与有毒物质（即铅）的存在有关，并伴随着对健康和环境的关注。这些担忧严重阻碍了它们的商业化。迄今为止，仅发现了一些可行的替代Pb的方法，在功率转换效率方面落后。在这里，提出了一种前瞻性的观点，提出了各种潜在的策略来克服与可操作的HP太阳能电池使用和释放铅有关的环境和健康问题。审查了可能的铅泄漏途径和相关的“补救”工具，并整理了可能的策略，以期开始一个新的含铅惠普设备时代。最后，通过与现有基于铅的技术进行比较，进行了一项比较研究，以提供对于真正评估铅含量对惠普商业化的影响至关重要的工具。
