在过去的几年中，由于其低成本和高功率转换效率，永久光伏（PV）电池引起了极大的兴趣。虽然钙钛矿光伏电池仍在开发中，但我们分析了钙钛矿光伏电池的替代可持续寿命终止管理的成本;这允许重复使用具有经济价值的材料并防止环境污染。在这里，我们研究了从废钙钛矿PV中回收铅、铝、金、镍和银等金属以及玻璃等其他有价值材料的生命周期成本评估。我们还开发了一种回收方案，以优化材料回收，并确定经济可行的方法来逐层分离细胞。我们评估了钙钛矿PV回收工艺的成本和净成本。我们发现，最可行的回收技术的成本是10.70美元，其净成本是每平方米模块-2.95美元。这些价值可以通过优化和重复使用过程中涉及的化学品进一步提高。这些结果表明，钙钛矿PV回收的成本在经济上是可行的，并且有可能从钙钛矿PV的可持续寿命终了管理中获益。图形摘要
Perovskite photovoltaic (PV) cells have created a significant interest over the last few years due to their low-cost and high-power conversion efficiencies. While perovskite PVs are still under development, we analyze cost of alternative sustainable end-of-life management for perovskite PV cells; this allows to reuse economically valuable materials and prevent environmental contamination. Here, we studied the life cycle cost assessment of recovering metals such as lead, aluminum, gold, nickel, and silver and other valuable materials such as glass from waste perovskite PVs. We also developed a recycling scheme to optimize the material recovery and determine the economically feasible ways to separate the cells layer-by-layer. We assessed the cost and the net cost of the perovskite PV recycling processes. We found that the most feasible recycling technique’ cost is $10.70 and its net cost is $− 2.95 per 1 m^2 module. These values could be further improved by optimizing and reusing chemicals involved in process. These results indicate that the cost of perovskite PV recycling is economically feasible and there is potentional to gain benefit from sustainable end-of-life management of perovskite PVs.
