A solar cell packaging frame

Abstract

The invention discloses a solar cell encapsulation frame, belonging to the technical field of solar cells, comprising a frame body, a sealing mechanism is arranged inside the frame body, a laminate is arranged in the frame body through the sealing mechanism, and a junction box is arranged at one end of the laminate. One end of the frame main body is provided with a sealing plate through the sealing mechanism, the sealing plate is fixedly connected with the frame main body through the connecting component, the frame main body, the laminated plate and the sealing plate form a sealing cavity through the sealing mechanism, and the sealing cavity is filled with sealing liquid. Compared with the prior art, the beneficial effect of the present invention is that the structure of the present invention is simple, and the installation is convenient, and the problem that the sealability of the sealing chamber cannot be detected after the seal failure is solved by using the sealing liquid in the sealing frame, and the laminated board is sealed by the sealing liquid It plays a certain role of sealing and protection. At the same time, the integral frame body is used to ensure the strength of the solar cell. The installation process is relatively simple, and the technical requirements for installation are relatively low.

Description

technical field [0001] The invention relates to the technical field of solar cells, in particular to a solar cell packaging frame. Background technique [0002] A solar cell is an energy conversion device that directly uses sunlight to generate electricity. It can convert light energy into electrical energy. It only needs to place the solar cell under a certain illuminance of sunlight to directly output voltage, which can be output to the connected circuit. current. [0003] Existing solar cells generally include tempered glass, EVA, cells, backplane, aluminum alloy frame and junction box, as well as silicone for sealing. , the laminate is assembled with the junction box and the aluminum alloy frame to form a solar cell. Silicone is generally used to seal the gap between the aluminum alloy frame and the junction box. The effect of the glue seal is to ensure that the laminate can be closely attached to the aluminum alloy frame. Together, it has a certain waterproof effect, ...

Problems solved by technology

[0004] After the solar cell laminate is irradiated by the sun, the temperature will rise, and the size will change to a certain extent. There will be a certain displacement between the laminate and the aluminum alloy frame. The degree of expansion of the smaller laminate is limited. The silicone rubber has a certain degree of elasticity, which will not affect its sealing effect. However, when the size of the laminate is larger, the degree of thermal expansion increases. The silicone on the aluminum alloy frame expands and contracts repeatedly through the laminate, and the silicone and layer If the pressure plate or the aluminum alloy frame is degummed, once the degumming occurs, it is impossible to tell whether the airtightness of the outer tube is good
