In recent years, academia and industry have shown interest in the application of inkjet printing technology in the field of perovskite solar cells. The chemical formula of lead halide perovskite is APbX3. Among them, A represents a monovalent cation, and X represents a monovalent halide anion.

[0003] An inkjet printing device is a device that changes liquid ink into fine particles through a nozzle and sprays it onto a substrate. The printhead is the most critical part of the printer. If the printhead is not properly maintained, even the best equipment cannot function normally. Ink pressing and flash spraying are common and effective maintenance methods that can effectively reduce the occurrence of printhead clogging problems.

[0004] However, the prior art has the following defects: on the one hand, the pressed ink generally needs to be discharged into a liquid receiving box, and the liquid receiving box is generally made of hard material. During equipment operation, it cannot be guaranteed that the printhead and the liquid receiving box will not collide and be damaged. On the other hand, during the flash spraying process, ink droplets (perovskite solution or organic amine salt droplets) will drift and disperse inside the inkjet printing device, causing corrosion of metal parts, and thus affecting the mechanical operation accuracy of the equipment. At the same time, existing research has shown that lead halide perovskite will react with common metals including aluminum, silver and gold in the air.

[0005] Therefore, there is a problem in the prior art that the printhead of the inkjet printer cannot be protected and ink droplets cannot be prevented from spreading when the printhead is maintained. UTILITY MODEL CONTENT
