摘      要：Perovskite solar cells(PSCs)have reached a recorded power conversion efficiency(PCE)of 25.7%just over a decade.1 Due to the solution processability,various deposition methods have been developed to prepare PSCs,including spin coating,blade coating,spray coating,slot-die printing,and ink-jet printing.2,3 Among them,screen printing has received great attention due to the unique advantages of customized pattern design,high throughput,and low-cost production.Thus this technology holds a great promise for industrialization of perovskite solar cells.4 Till now,screen printing has been successfully applied to prepare buffer layers and electrodes of PSCs,but attempts in perovskite-layer fabrication have failed.The key problem is that the commonly used organic solvents with a low viscosity are not fit for screen printing,which limits the application of this deposition technology for perovskite-film manufacturing.
