Abstract

The one-step antisolvent method is an important approach for preparing high-quality perovskite films and high-performance perovskite solar cells (PSCs). However, the main solvents N,N-dimethylformamide (DMF) and antisolvent chlorobenzene (CB) commonly used in this process are highly volatile toxic, which pose a serious threat to environmental safety and human health, and are not conducive to the commercialization of PSCs. Therefore, we have developed a new perovskite precursor solution system to prepare high-quality FA_0.9Cs_0.1PbI₃ perovskite films. We used a less toxic N-methylpyrrolidone (NMP) as the solvent and a green ethyl methyl carbonate (EMC) as the antisolvent. The morphology of perovskite films prepared with EMC antisolvent and the typical green antisolvent ethyl acetate (EA) and the performance of the corresponding PSCs were compared. It's found that EMC-processed perovskite films have better crystallinity with fewer defects. Also, with better energy level alignment, the EMC-processed PSCs achieved a photoelectric conversion efficiency (PCE) of 19.68%, much higher than that of EA-processed PSCs (17.98%).

绿色抗溶剂碳酸甲酯乙酯制备的高性能钙钛矿太阳能电池

一步反溶剂法是制备高质量钙钛矿薄膜和高性能钙钛矿太阳能电池（PSCs）的重要途径。但该工艺中常用的主要溶剂N，N-二甲基甲酰胺（DMF）和抗溶剂氯苯（CB）具有高挥发性毒性，对环境安全和人体健康构成严重威胁，不利于PSCs的商业化。因此，我们开发了一种新的钙钛矿前驱体溶液体系来制备高质量的FA0.9Cs0.1PbI3钙钛矿薄膜。我们使用毒性较小的n -甲基吡咯烷酮（NMP）作为溶剂，绿色的甲基碳酸乙酯（EMC）作为抗溶剂。比较了用EMC反溶剂和典型的绿色反溶剂乙酸乙酯（EA）制备的钙钛矿膜的形貌和相应的聚丙烯酸甲酯的性能。研究发现，emc法制备的钙钛矿薄膜结晶度好，缺陷少。此外，在更好的能级对准下，emc处理的PSCs的光电转换效率（PCE）达到19.68%，远高于ea处理的PSCs（17.98%）。
