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.
