Abstract The environmental performance of four different device assembly procedures based on hybrid halide perovskite solar cell (PSC) were assessed from cradle to grave using life cycle assessment (LCA) methodology. In addition, a new environmental indicator was defined to measure the time evolution of an impact category, specifically in this case, human toxicity cancer payback time. PSCs procedures accounted for the probably three more used basic recipes for laboratory perovskite deposition: 1) spin coating of stoichiometric precursor solution, 2) spin coating of precursor solution using lead chloride precursor and 3) the two step deposition method. Also, the two most widely used substrate configurations (planar and mesoporous substrate)were considered. LCA included three realistic scenarios for the end of life: 1) residual landfill, 2) reuse and residual landfill and 3) reuse and recycling. The remaining variable parameters to assemble the device were fixed in common for all four devices, which were the major responsible of the whole PSC impact. Lead of PSCs had no significant contribution in environmental impacts. Beyond shared procedure steps, impacts generated by the two-step method and the use of mesostructured type substrate were higher. End of life scenario with reuse and recycling improved the toxicity impact categories.

基于生命周期评估的甲基铵三碘化铅钙钛矿太阳能电池的相对影响

摘要 使用生命周期评估 (LCA) 方法从摇篮到坟墓评估了基于混合卤化物钙钛矿太阳能电池 (PSC) 的四种不同设备组装程序的环境性能。此外，还定义了一个新的环境指标来衡量影响类别的时间演变，特别是在这种情况下，人类毒性癌症的回报时间。PSC 程序可能占实验室钙钛矿沉积的三个更常用的基本配方：1) 化学计量前体溶液的旋涂，2) 使用氯化铅前体旋涂前体溶液和 3) 两步沉积方法。此外，还考虑了两种最广泛使用的基材配置（平面和介孔基材）。LCA 包括寿命结束的三个现实场景：1) 剩余垃圾填埋场，2) 再利用和剩余垃圾填埋场以及 3) 再利用和回收利用。组装设备的其余可变参数对于所有四个设备都是固定的，它们是整个 PSC 影响的主要负责人。PSCs的铅对环境影响没有显着贡献。除了共享程序步骤之外，两步法和使用介孔结构型基板产生的影响更大。再利用和回收利用的报废情景改善了毒性影响类别。两步法和使用介孔结构型基板产生的影响更大。再利用和回收利用的报废情景改善了毒性影响类别。两步法和使用介孔结构型基板产生的影响更大。再利用和回收利用的报废情景改善了毒性影响类别。
