Perovskite solar cells (PSCs) have increased in power conversion efficiency in the last 10 years, from ≈3% to now over 25%. While the best perovskite photovoltaics have remarkable efficiencies, the Pb‐based absorber is likely problematic for commercialization due to environmental concerns. To address this inevitable issue, a porous metal–organic framework (MOF) polymer composite is applied, known as FeBTC/PDA that is used in “safe‐by‐design” perovskite solar panels. The material is based on a porous MOF scaffold containing a polymeric metal binding agent. Herein, the activity of this material to sequester lead from several solutions is demonstrated, including simulated perovskite solutions, solutions containing decomposed perovskite thin films, and real‐world solutions obtained from damaged solar cell devices in a range of temperatures and conditions, and contaminated water derived from damaged PSCs is brought below the drinkable standards set by the Environmental Protection Agency (EPA).

使用金属-有机骨架聚合物复合材料从钙钛矿太阳能电池中隔离铅

钙钛矿太阳能电池（PSC）的功率转换效率在过去10年中已经从大约3％提高到现在的25％以上。尽管最好的钙钛矿光伏电池具有显着的效率，但由于对环境的关注，基于铅的吸收剂可能在商业化方面存在问题。为了解决这个不可避免的问题，应用了一种多孔金属-有机骨架（MOF）聚合物复合材料，称为FeBTC / PDA，用于“按设计安全”钙钛矿太阳能电池板。该材料基于含有聚合金属粘合剂的多孔MOF支架。在此，从模拟溶液中钙钛矿溶液，包含分解的钙钛矿薄膜的溶液，
