In order to achieve the large-area,uniform,and high-quality electronic devices,improve the printing quality and stability,the inkjet printing parameters control should be investigated.In this study,with the perovskite ink,the inkjet printing parameters such as ink droplet spacing and nozzle voltage were controlled to research the effect of the ink jetting spray state on the morphology of the result layer and printing effects.The results indicated that the appropriate range of ink droplet spacing was related to the spreading radius of ink droplets.Under the conditions of this experiment,when the nozzle voltage was 12V and the distance between ink droplets was 16-22μm,the inkjet state and ink layer printing effect were better.This study can provide a reference for the preparation of new functional material devices by inkjet printing.
