Embodiment 1

[0036] Such as figure 1 As shown, the solar cell double-glass module 10 of the embodiment of the present invention includes a front glass 1 and a back glass 2 . Wherein, a solar cell 3 is encapsulated between the front glass 1 and the back glass 2 , and the solar cell 3 is located on the back glass 2 . The back glass 2 is provided with a conductive bus bar 4 connected to the solar cell 3 , and the conductive bus bar 4 passes through the back glass 2 and is connected to the junction box 5 . The junction box 5 is provided with a connection terminal 51 connected to the conductive bus bar 4 , and the connection terminal 51 and the conductive bus bar 4 are connected by filling with a curable conductive fluid. The junction box 5 is used for connecting with an external cable 6 .

[0037] According to the solar cell double-glass module of the embodiment of the present invention, the connection terminal is fully connected to the conductive bus bar by filling it with a curable conduct...

Embodiment 2

[0042] Such as figure 1As shown, the method for assembling the solar cell double-glass module 10 according to the embodiment of the present invention includes the following steps: S01, after drilling the back glass 2 provided with the solar cell and laying the conductive bus bar 4, the conductive bus bar 4 It is connected with the solar cell 3 and leads out the backplane glass 2 through the drilled hole. S02 , introducing the conductive bus bar 4 into the groove structure 511 in the connection terminal 51 of the junction box 5 . S03. Fill the groove structure 511 of the connection terminal 51 with a curable conductive fluid. S04, curing the conductive fluid.

Abstract

The invention provides a solar cell double-glass assembly and an assembling method thereof. The solar cell double-glass assembly comprises front plate glass and back plate glass. A solar cell is packaged between the front plate glass and the back plate glass, and the solar cell is located on the back plate glass. The back plate glass is provided with a conductive bus bar connected with the solar cell, and the conductive bus bar passes through the back plate glass and is connected with a junction box. A wiring terminal connected with the conductive bus bar is arranged in the junction box, and the wiring terminal and the conductive bus bar are connected in a curable conductive fluid filling mode. According to the solar cell double-glass assembly and the assembling method thereof, the problems that the service life of the solar cell double-glass assembly is shortened even a fire disaster is caused and the efficiency of the solar cell is reduced due to overlarge series resistance in an existing bus bar connecting mode can be solved.

Description

technical field [0001] The invention relates to the technical field of solar cells, in particular to a solar cell double-glass component and an assembly method thereof. Background technique [0002] At present, the connection process between the bus bar and the junction box of the solar cell double-glass module is mostly connected by copper strips and the internal terminals of the junction box by welding or clamping. This connection method may have the problem of poor welding or unreliable fixing of the fixture. On the one hand, it increases the series resistance of the module and reduces the efficiency of the battery. Even cause a fire. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art, provide a solar cell double-glass module and its assembly method, and use a curable conductive fluid filling method to connect the internal conductive bus bar and wiring of the solar cell double-...
