Description

Technical Field

[0001] The utility model belongs to the technical field of solar cells, and specifically relates to a perovskite solar cell packaging structure. Background Art

[0002] Perovskite solar cells are solar cells that use perovskite-type organic metal halide semiconductors as light-absorbing materials. During the production process of perovskite solar cells, in order to extend the service life of the battery body, it is often necessary to use a packaging structure to encapsulate and protect the battery body.

[0003] The Chinese patent with application number CN202221307116.6 discloses a perovskite solar cell packaging structure, including a sealing tank body, a battery body is placed inside the sealing tank body, a sealing plate is attached to the top of the battery body, a sealing ring is fixedly connected to the sealing plate around the four sides, one side of the sealing ring is attached to the inner wall of the sealing tank body, a connection box is fixedly connected to the top of the sealing plate, a plurality of connection holes are opened on one side of the connection box, an electrode plate is fixedly arranged at the bottom of the connection hole, and a connection assembly is arranged in the connection hole. By setting up the installation assembly, the clamping ring drives the clamping block to move through the triangular plate, and when the clamping ring completely enters the groove, the second spring drives the clamping block to be clamped into the clamping ring through the limit plate to achieve the limit fixation of the clamping ring, thereby realizing the quick disassembly and assembly between the mounting plate and the sealing tank body, reducing the steps of battery body packaging, improving the installation efficiency, and facilitating the replacement and maintenance at a later stage. However, when the above device is actually used, the connection hole on one side of the connection box is not protected. When wiring, it is necessary to frequently turn the adjustment screw to connect the wires, which is cumbersome to operate. When removing the mounting plate, it is necessary to pull multiple second sliding rods to release the fixation of the mounting plate. When installing the mounting plate, it is also necessary to insert the retaining ring into the corresponding retaining groove, which is troublesome to use.

[0004] In view of this, the present utility model is proposed. Utility Model Content
