Description

Technical Field

[0001] The utility model belongs to the technical field of spinning and winding, and in particular relates to a mixing agitator for 3D printing perovskite solution. Background Art

[0002] Organic-inorganic hybrid perovskite materials have gradually gained a place in the optoelectronic field due to their excellent semiconductor properties and low cost, and have become a material comparable to silicon. It is well known that semiconductor materials often need to meet the requirements of controllable shape and crystallinity in the application of optoelectronic devices. In the work that has been reported, the regulation of perovskite morphology has been successfully achieved, but these works are currently still at the level of regulation inside the film or with a small aspect ratio. Obviously, there is still a big gap between this and the controllability requirements of materials in modern optoelectronic processes. At present, the method of nanotube-guided crystallization is used to obtain three-dimensional direction-controllable perovskite nanomaterials, achieving a zero breakthrough in perovskite nanostructures in 3D printing technology. The preparation method is to use nanotubes to accurately locate and guide the perovskite solution to crystallize in a specific direction.

[0003] Before introducing the perovskite solution into the nanotubes, it needs to be stirred. Since the nanotubes are thin, the outlet of the cheap nanotube stirrer is also thin, and it is difficult to set a switch on it. To solve the above problem, a mixing stirrer for 3D printing perovskite solution is provided.
