Embodiment 1

[0030] Such as Figure 1-3 As shown, the solar battery assembly of the present invention is composed of several solar battery sheet packaging monomers.

[0031] The solar cell packaging unit includes solar cells 3, reinforcing patches 5, reinforcing hoops 7, elastic connecting sheets 6, elastic films, packaging gases, flexible conductive soldering strips 4, external interfaces 11, and connecting plugs. Wherein the solar cells 3 are monocrystalline silicon cells, polycrystalline silicon cells or other sheet-shaped fragile solar cells. The positive and negative poles of the solar cell 3 are welded with the flexible conductive ribbon 4, and the back of the solar cell 3 is pasted with an insulating lightweight reinforcing patch 5 slightly larger than the solar cell or battery string, the reinforcing patch 5 and the reinforcing hoop 7 are connected with elastic connecting piece 6. The elastic film is distributed on the top and bottom of the sheet-like combination formed by the so...

Embodiment 2

[0043] Such as Figure 6-7 As shown, the structure of this embodiment is basically the same as that of Embodiment 1, the difference is that the structure of the reinforcing ribs has been improved. In this embodiment, the reinforcing hoop 7 is a grid with holes, and the solar cells 3 pass through the elastic connecting piece 6 Fits in the holes of the grid. The solar cells are connected in series and parallel in a preset matrix form, with reinforcement patches on the back, the reinforcement patches are connected on the same plane or plane grid through elastic connecting pieces, and the grid is surrounded by a continuous raised transparent elastic film seal. The enclosing space is filled with the encapsulating gas of the first embodiment, and there are gaps communicating between each protrusion. The positions of the protrusions of the transparent elastic film material correspond to the positions of the solar cells one by one, and the shape of the protrusions can be the shape d...

Abstract

The invention discloses a solar cell module and a packaging method. The solar cell module comprises a solar cell and a flexible conductive welding strip connected with the solar cell, wherein a reinforcing hoop is arranged outside the solar cell; a reinforcing patch is arranged on the back of the solar cell; the reinforcing patch is connected with the reinforcing hoop through a plurality of spaced elastic connectors; an elastic film is packaged on each of the upper and lower surfaces of the reinforcing hoop, wherein the elastic film positioned on the upper surface of the reinforcing hoop is a transparent film; and a packaging gas of which the pressure is 1 to 5 bar is filled between the upper and lower elastic films. Compared with the prior art, the solar cell module has the advantages that the solar cell is connected with the reinforcing hoop through the elastic connectors, so that the structure of the solar cell module is simplified; and a combination mode of the reinforcing hoop and the elastic films is adopted, and the elastic films are supported by the reinforcing hoop and can buffer probable impact of an external force on the solar cell, so that normal work of the solar cell is protected.

Description

Technical field: [0001] The invention belongs to a new type of solar cell assembly, and relates to a new structure and method for packaging solar cells into an assembly. Background technique: [0002] The existing packaging methods for crystalline silicon cells mostly focus on using hard materials as the stress-bearing parts of the components to provide the necessary mechanical strength of the components during use and to ensure that the components are not easily damaged by external forces. The force-bearing parts not only take up a large volume, but also account for most of the weight of the solar cell module, which in turn results in a large proportion of the finished product and low power density. And due to its own weight, it brings additional requirements for structural strength during installation and use. Invention content: [0003] The technical problem to be solved by the present invention is to provide a solar cell module with light weight and higher power densi...
