摘要
目前,钙钛矿太阳能电池的发展非常迅速,但其稳定性差的问题仍有待解决.稳定的前驱体溶液对于大规模制备高质量的钙钛矿薄膜至关重要.本文通过使用多功能离子液体1-n-丁基-3-甲基咪唑啉,二-n-丁基磷酸盐(BMIMBP)作为抗老化添加剂,成功地开发了一种提高前驱体溶液的长期稳定性和电池性能的策略.BP-可以通过多种化学键抑制I-和FA+的反应性,从而提高前驱体溶液的稳定性.此外,带有胺基的BMIM+可以在内部形成二维钙钛矿,增强了器件的稳定性.本文为稳定钙钛矿太阳电池的商业化应用提供了一类行之有效的方法.
Abstract
At present,the development of perovskite solar cells(PSCs)is progressing rapidly,but the issue of poor sta-bility remains a significant challenge.Achieving a stable pre-cursor solution is crucial for the large-scale production of high-quality PSC films.In this study,we successfully devel-oped a strategy to improve the long-term stability of the pre-cursor solution and improve device performance by employing 1-n-butyl-3-methylimidazolium di-n-butyl phosphate(BMIMBP)as an anti-aging additive.The BP-component inhibits the reactivity of I-and formamidinium ion through multiple chemical bonds,thereby stabilizing the precursor solution.In addition,the BMIM+component,which contains an amino group,can form two-dimensional perovskite in-ternally,further enhancing the device stability.This strategy provides valuable guidance for achieving long-term stability in solar cells.
