Beschreibung
Zusammenfassung:The invention relates to the field of batteries, and provides an ionic liquid and a preparation method thereof, a perovskite solar cell and a preparation method thereof, and a photovoltaic module, the ionic liquid comprises # imgabs0 #, R1 comprises an alkyl chain; r2 comprises at least one of-COOH,-B (OH) 2,-PO (OH) 2,-CF3,-NH2 and-SO3H; ar comprises heteroaromatic rings containing substituent groups. Therefore, the ionic liquid is added into the perovskite layer, so that the long-term stability of the perovskite layer can be improved, and the photoelectric conversion efficiency of the perovskite solar cell is improved. 本申请涉及电池领域，提出了离子液体及制备方法、钙钛矿太阳能电池及制备方法、光伏组件，所述离子液体包括#imgabs0#，其中，R1包括烷基链；R2包括-COOH、-B(OH)2、-PO(OH)2、-CF3、-NH2、-SO3H中的至少一种；Ar包括含有取代基的芳杂环。由此，在钙钛矿层中加入所述离子液体，可以提高钙钛矿层的长期稳定性，提高钙钛矿太阳能电池的光电转换效率。
