由于其低成本和高功率转换效率，Percent太阳能电池引起了极大的关注。然而，在钙钛矿染料中使用铅等有毒金属以及钙钛矿太阳能电池的处理方法引起了对其环境影响的严重关注。已经开发了无机和无铅钙钛矿太阳能电池以克服铅基有机钙钛矿太阳能电池的缺点，这一发展涉及不同的材料和制造工艺来制造不同的钙钛矿太阳能电池。为了了解和开发环境友好的钙钛矿太阳能电池技术，本研究采用归因生命周期评估（LCA）方法对五种典型的钙钛矿太阳能电池进行了全面的环境影响评估。结果表明，MAPbI3和FAPbI3钙钛矿太阳能电池比MASnI3−xBrx，CsPbBr3和MAPbI2Cl钙钛矿太阳能电池具有相对较大的环境影响，基于1 cm2有效面积太阳能电池系统，这一结果可以通过器件制造中使用的有机溶剂量不同来解释。此外，金生产对钙钛矿太阳能电池系统的环境影响贡献最大，用银或铝替代金可以显著降低总的环境影响分数。就处置方法而言，发现具有能量回收的焚烧优于填埋。
Perovskite solar cells have attracted enormous attention due to their low cost and high power conversion efficiency. However, the use of toxic metals such as lead in the perovskite dye and the disposal methods of perovskite solar cells cause grave concerns about their environmental impacts. Inorganic and lead-free perovskite solar cells have been developed to overcome the disadvantages of lead-based organic perovskite solar cells, a development that involves different materials and manufacturing processes to fabricate different perovskite solar cells. In order to understand and develop an environmentally friendly perovskite solar cell technology, comprehensive environmental impact assessments have been conducted in this study on five typical perovskite solar cells, using an attributional life cycle assessment (LCA) approach. The results indicate that MAPbI3and FAPbI3perovskite solar cells have relatively larger environmental impacts than MASnI3−xBrx, CsPbBr3, and MAPbI2Cl perovskite solar cells based on a 1 cm2active area solar cell system, and this result can be explained by the different amounts of organic solvents used in the device fabrication. In addition, gold production makes the largest environmental impact contribution to perovskite solar cell systems, and the substitution of silver or aluminum for gold can significantly reduce the total environmental impact scores. For disposal methods, incineration with energy recovery is found better than landfill.
