摘要

摘要钙钛矿薄膜的质量高度影响钙钛矿太阳能电池（PSC）的性能。为了沉积均匀致密的钙钛矿膜，制造过程通常在手套箱等受控环境中进行，这限制了未来的商业发展。使用由乙酸乙酯（EA）和乙醚（DE）组成的混合抗溶剂在高湿度下制备了高质量的钙钛矿膜。研究发现，通过调节混合反溶剂中EA和DE的体积比，提高钙钛矿薄膜的晶粒尺寸，可以控制钙钛矿结晶的速度。在70%的湿度下，用最佳比例EA和DE处理的PSC的效率从11.07%提高到18.77%。我们的工作为在高湿度环境中制造高效PSC提供了一种方便的策略。

Highly efficient perovskite solar cells fabricated in high humidity using mixed antisolvent

Abstract. The quality of the perovskite film highly affects the performance of perovskite solar cells (PSCs). To deposit uniform and dense perovskite films, the fabrication processes are usually conducted in a controlled environment such as a glove box, which limits the future commercial development. High-quality perovskite films were fabricated in high humidity using mixed antisolvent consisting of ethyl acetate (EA) and diethyl ether (DE). It is found that the speed of perovskite crystallization could be controlled by adjusting the volume ratio of EA and DE in the mixed antisolvent, enhancing the grain size of perovskite films. The PSC fabricated in a humidity of 70% treated with an optimal ratio EA and DE exhibits an enhanced efficiency of 18.77% from 11.07%. Our work provides a convenient strategy for fabricating highly efficient PSCs in a high-humidity environment.
