(a) Represents the important steps involved in inkjet printing of triple-cation multicrystalline perovskite (TCP) thin films: (1) ink preparation, (2) inkjet printing, (3) drying and annealing: The printed TCP wet film is transferred to a vacuum chamber to accelerate the rate of removal of the solvents to induce nucleation of the perovskite thin film. (b) SEM images of cross sections of PSCs with inkjet-printed perovskite films with different resolutions. Reproduced with permission from ref. [174], Copyright 2020, Advanced Energy Materials.
