Description

Technical Field

[0001] This utility model relates to the field of coating and adsorption platform technology, and in particular to a CIGS large-area perovskite multilayer coating and adsorption platform. Background Technology

[0002] Currently available coating platform devices are difficult to apply to CIGS perovskite multilayer coating, and the adsorption substrates are all large in size. CIGS substrates are long strips, and after being cut by machine, the edges are curved downwards and curled up. This results in a concave center and high sides on conventional adsorption platforms. During coating, the perovskite solution will converge in the center, resulting in uneven solution distribution and poor film quality. Utility Model Content

[0003] In view of this, the purpose of this utility model is to propose a CIGS large-area perovskite multilayer coating adsorption platform to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides an adsorption platform for large-area CIGS perovskite multilayer coating, comprising an adsorption platform body, a vacuum interface and a compressed air interface connected to one side of the adsorption platform body, a plurality of first micro-adsorption holes on the top of the adsorption platform body, a plurality of anti-warping areas on the top of the adsorption platform body, a first gap between each anti-warping area, each anti-warping area being composed of two grooves, a second gap between the two grooves in each anti-warping area being larger than the first gap, and a plurality of second micro-adsorption holes between the two grooves in each anti-warping area.

[0005] Preferably, the distance of the first gap is 4-5 mm.

[0006] Preferably, the distance of the second gap is 40-50mm.

[0007] Preferably, the length of each groove is 150-160 mm.

[0008] Preferably, the gap between the two first micro-adsorption pores is three times the gap between the two second micro-adsorption pores.

[0009] The beneficial effects of this utility model are as follows: by adding grooves, the warped part of the CIGS film is placed in the grooves, which solves the problem of the middle depression and the two sides being high caused by the warped edge. At the same time, a certain number of second micro-adsorption holes are added to increase the adsorption area of ​​the film, so that the film is adsorbed and the flatness of the adsorption is improved.
