Detailed Description
Hereinafter, embodiments of the present invention will be described in detail.
In the invention, the inner side of the back plate refers to the side of the back plate facing the battery piece after the back plate is installed in the solar battery module; it is understood that the side of the back plate away from the battery piece is the outer side of the back plate.
Fig. 1 illustrates a structure of a back sheet for a solar cell module according to the present invention, and as shown in fig. 1, the back sheet includes a substrate, and a pattern layer 31 containing an ultraviolet absorber having a predetermined pattern disposed on an inner surface of the substrate.
According to the back plate of the solar cell module, the pattern layer containing the ultraviolet absorbent is arranged on the inner side surface of the substrate, namely the ultraviolet-resistant functional material layer is arranged on the local area of the inner side surface of the substrate, so that the ultraviolet absorbent absorbs ultraviolet light, the damage of the ultraviolet light to other parts of the back plate is reduced, the ultraviolet-resistant performance of the inner side of the back plate is enhanced, and the power of the module is improved.

It can be understood that due to the shielding of the battery piece 10, the ultraviolet light does not irradiate the area of the back plate shielded by the battery piece 10.
As shown in fig. 5, the pattern of the pattern layer 31 containing the uv absorber is in a grid shape, and the back sheet is suitable for a solar cell module in which cells are connected by solder ribbons and a certain gap is formed between the cells.
As shown in fig. 6, the pattern of the pattern layer 31 containing the uv absorber is a stripe shape, and the back sheet is suitable for a laminated assembly, that is, adjacent cells in a cell string of the same string are connected in a laminated manner, there is no gap between adjacent cells in the cell string of the same string, and there is a gap between two adjacent strings.
Of course, in the present invention, the pattern of the pattern layer 31 containing the ultraviolet absorber is not limited to a grid or a strip, and may be set according to the type of the module, and the pattern may correspond to an area of the battery piece layer that is not blocked by the battery piece.

The ultraviolet absorber-containing coating may be a heat-curable ultraviolet absorber-containing coating, preferably a low-temperature-curable (curing temperature 60 ℃ or lower) ultraviolet absorber-containing coating. When preparing the pattern layer 31 containing the ultraviolet absorber, a coating material containing the ultraviolet absorber is disposed on the inner surface of the substrate according to the pattern of the pattern layer 31 containing the ultraviolet absorber (for example, the region 11 of the battery sheet 10 that is not covered by the battery sheet), and the coating material containing the ultraviolet absorber is cured to form the pattern layer 31 containing the ultraviolet absorber.
The uv absorber-containing coating may be applied to the inside surface of the substrate by cross-hatch coating, spraying, coating, printing, and the like.
