In recent years, remarkable progress has been made in the field of metal halide perovskite solar cells, resulting in power conversion efficiencies (PCE) surpassing 26%. These advances are made possible by compositional and additive engineering of the perovskite active layer and the development of more efficient charge extraction layers. Most research efforts are dedicated to processing perovskites from solution, often from highly toxic solvents such as dimethylformamide (DMF). While this is manageable for lab-scale fabrication, using such solvents raises considerable safety and environmental concerns about fabricating perovskite devices on a mass scale. To solve this challenge, green solvents suitable for perovskite processing must be identified, and perovskite deposition processes must be adapted to the properties of the new solvents. Alternatively, solvent-free deposition methods must be developed that are compatible with industry processing on a large scale. In this talk, I will present promising green solvent alternatives to DMF and highlight recent developments in vapor-based deposition methods of metal halide perovskites.
