In recent years, remarkable progress has been made in the field of metal halide perovskite solar cells, resulting in power conversion efficiencies (PCE) that surpass 27%. As the vast majority of research efforts are dedicated to their processing from solution, the use of the highly toxic, yet ubiquitously used, dimethylformamide (DMF) for the processing of perovskite represents a major hurdle for their adaptation in industrial applications on the large-scale. In the first part of this talk, I will propose a strategy for selecting green solvent alternatives to DMF that enable a more sustainable processing of perovskite based solar cells. To validate the proposed selection strategy, I will demonstrate the ability of multiple green solvents to be used to fabricate efficient perovskite solar cells. In the second part of the talk, I will introduce novel strategies for a solvent-free fabrication of perovskites by vapor deposition, focusing on addressing the current challenges of this deposition method.
