Abstract

The commercialization of perovskite solar cells (PSCs) technology is in full swing, but the ecotoxicity of the solvents involved in perovskite processing remains a barrier. Herein, a low-toxicity 1,3-dimethyl-2-imidazolidinone(dimethyl sulfoxide) solvent system, abbreviated as DMI(DMSO), has been designed to support the green fabrication of perovskite films and PSCs. Both DMI and DMSO can be proposed as less-toxic solvents. By optimizing the volume ratio of DMSO cosolvent in DMI(DMSO) solvent system, the morphologies, optical properties and photovoltaic performance of perovskite films can be well modulated. The delivered planar PSCs achieved a best power conversion efficiency of up to 20.24 %, comparable to those of devices based on the traditional solvent systems. This work provides a feasible way to produce scalable PSCs with high efficiency using an environmentally benign solvent system.

一种低毒性前驱体溶剂体系实现了高性能钙钛矿太阳能电池的绿色制造

钙钛矿太阳能电池（PSCs）技术的商业化正如火如荼地进行，但涉及钙钛矿加工的溶剂的生态毒性仍然是一个障碍。本文设计了一种低毒性的1,3-二甲基-2-咪唑烷酮（二甲亚砜）溶剂体系，简称DMI(DMSO)，以支持钙钛矿薄膜和聚氯乙烯的绿色制备。DMI和DMSO都可以作为毒性较低的溶剂。通过优化DMSO共溶剂在DMI（DMSO）溶剂体系中的体积比，可以很好地调节钙钛矿薄膜的形貌、光学性质和光伏性能。所交付的平面PSCs的最佳功率转换效率高达20.24%，与基于传统溶剂系统的器件相当。这项工作提供了一种可行的方法来生产可扩展的psc与高效使用环境友好的溶剂体系。
