[0019] In order to make the purpose, technical solution and advantages of the present invention more clear, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be noted that the embodiments of the present invention and the features therein can be combined with each other unless there is any conflict.

[0020] The following describes a perovskite cell scribing and edge cleaning device provided by some embodiments of the present invention in conjunction with the accompanying drawings.

[0021] Example:

[0022] Combine Figure 1-3As shown, the utility model provides a perovskite cell scribing and edge cleaning device, including a moving mechanism, a scribing mechanism and an edge cleaning mechanism. The moving mechanism includes a base frame 110, a lower track 120 installed in the middle of the upper surface of the base frame 110, a carrier platform 130 sliding on the lower track 120, a bracket 140 fixed on both sides of the base frame 110, a slide rail 150 installed at the front end of the bracket 140, a slide plate 160 slidably connected to the slide rail 150, and a vertical lifting motor 170 installed on the slide plate 160. A perovskite cell is placed on the carrier platform 130, and the vertical lifting motor 170 is used to control the lifting of the slide plate 160. The scribing mechanism includes a laser emitter 210 fixedly installed on the top of the bracket 140, and a beam expander 210 installed on the bracket 140 and located in front of the laser emitter 210. 20. A marking mirror 230 for reflecting the laser beam after expansion by the beam expander 220, and a marking focusing mirror 240 arranged at the end of the marking mirror 230. The marking mirrors 230 are in groups of four, and the four marking mirrors 230 are all mounted on the bracket 140. A positioning camera 250 is mounted on the side of the slide 160 close to the marking focusing mirror 240. The positioning camera 250 is used to control the lifting and lowering of the slide 160, so that the height can be adjusted as needed. The lateral movement can be achieved in conjunction with the slide rail 150, which further improves the flexibility of the device. The edge cleaning mechanism includes an edge cleaning laser 310, an edge cleaning mirror 320 for reflecting the edge cleaning laser 310, an edge cleaning galvanometer 330 mounted on the rear side of the edge cleaning mirror 320, and an edge cleaning field mirror 340 fixedly mounted on the bottom of the edge cleaning galvanometer 330.

[0023] Specifically, three lines are scribed on the perovskite cell using a scribing mechanism, which is completed using a scribing focusing mirror 240. After the scribing step is completed, the coating on the four edges of the perovskite cell needs to be removed using an edge-cleaning structure, leaving only the glass substrate. This process only requires the edge-cleaning galvanometer 330 and the edge-cleaning field mirror 340 to complete. The steps are simple and efficient, which effectively improves the practicality of the device.

[0024] The working principle and usage process of the present invention are as follows: first, the perovskite cell is placed on the wafer carrier platform 130, and then the device is started. The positioning camera 250 is used in conjunction with the wafer carrier platform 130 to locate the position of the perovskite cell, and then the laser emitter 210 is started to mark the periphery of the perovskite cell. After the marking is completed around the perovskite cell, the edge cleaning mirror 340 is started to clean the edges.

[0025] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
