In 2020 dimethyl sulfoxide (DMSO), the ever-present solvent for tin halide perovskites, was identified as an oxidant for Sn . Nonetheless, alternatives are lacking and few efforts have been devoted to replacing it. To understand this trend it is indispensable to learn the importance of DMSO on the development of tin halide perovskites. Its unique properties have allowed processing compact thin-films to be integrated into tin perovskite solar cells. Creative approaches for controlling the perovskite crystallization or increasing its stability to oxidation have been developed relying on DMSO-based inks. However, increasingly sophisticated strategies appear to lead the field to a plateau of power conversion efficiency in the range of 10-15 %. And, while DMSO-based formulations have performed in encouraging means so far, we should also start considering their potential limitations. In this concept article, we discuss the benefits and limitations of DMSO-based tin perovskite processing.
2020年，二甲基亚砜（DMSO），这种卤化锡钙钛矿中一直存在的溶剂，被确定为锡的一种氧化剂。尽管如此，目前仍缺乏替代物，而且很少有人致力于替换它。为了理解这一趋势，了解DMSO在卤化锡钙钛矿发展中的重要性是必不可少的。其独特的性质使得能够制备致密的薄膜并将其集成到锡钙钛矿太阳能电池中。依靠基于DMSO的油墨，已经开发出了控制钙钛矿结晶或提高其抗氧化稳定性的创新方法。然而，越来越复杂的策略似乎使该领域的功率转换效率达到了10%-15%的平台期。而且，虽然基于DMSO的配方到目前为止表现令人鼓舞，但我们也应该开始考虑它们的潜在局限性。在这篇概念文章中，我们讨论了基于DMSO的锡钙钛矿加工的优点和局限性。
