Embodiment 1

[0046] like figure 1 As shown, the embodiment of the present invention provides a solar cell packaging process, and the solar cell packaging process includes:

[0047] Step 1, opening grooves on the curved backplane 3; the curved backplane 3 is generally a civil backplane, and its material can be a material with poor high temperature resistance;

[0048] Step 2, laminating the flexible photovoltaic module 1 without a backsheet.

[0049] like figure 2 Shown is a schematic diagram of the lamination process of the flexible photovoltaic module 1, the specific lamination process includes, the transparent flexible front plate film 11, the first encapsulation film 12, the flexible chip 13, the second encapsulation film 14, the isolation protection layer 15 ( The isolation protection layer 15 can be a structure such as a high-temperature cloth) stacked in sequence, and laminated (you can choose to laminate by a flat laminator); after lamination, the isolation protection layer 15 is...

Embodiment 2

[0066] In the embodiment of the present invention, the specific packaging steps are as follows:

[0067] like figure 1 and figure 2 As shown, the flexible photovoltaic module 1 without a backsheet, that is, the composite structure without a backsheet is to stack a transparent flexible front sheet film 11, an encapsulation film, a flexible chip 13, an encapsulation film, and a Teflon high-temperature cloth into a flat plate in sequence. Machine lamination; Teflon high-temperature cloth can be easily separated from the composite structure without backboard due to its high temperature resistance, smooth surface, and difficult bonding with the packaging film, so that the non-backboard composite structure can be completed. Composite structure fabrication process. The function of the Teflon high-temperature cloth is to prevent the bottom packaging film from overflowing and polluting the lamination equipment during the lamination process, resulting in irreversible damage to the eq...

Abstract

The invention discloses a solar cell packaging technology. The solar cell packaging technology firstly laminates a flexible photovoltaic module without a back sheet, and then packages a curved back sheet, thus avoiding the problem that the back sheet is cracked because non-uniform pressure during the lamination process so as to improve the production yield as the flexible photovoltaic module during the lamination process has no back sheet. Moreover, the flexible photovoltaic module removes the original composite back sheet, and is directly packaged into a groove of the curved back sheet, so that the load of the entire solar cell can be reduced, and the packaging cost can be greatly reduced at the same time.

Description

technical field [0001] The invention relates to the field of solar cell processing, in particular to a solar cell packaging process. Background technique [0002] As non-renewable energy sources are decreasing, the application of photovoltaic products is becoming more and more important. The current photovoltaic products usually have a curved surface shape. The conventional curved surface packaging process uses curved glass packaging materials as the base material, and the curved surface is laminated by using an autoclave. [0003] This kind of packaging method is easy to cause fragments in the lamination process due to uneven pressure, and the production yield is not high; the other method is to fit the complete flexible component including the composite backplane to the curved surface of the product, and attach it as an external structure. On the product; this method not only increases the load of the product but also limits the bending degree of the component due to the ...
