Abstract

The embodiment of the invention relates to the field of solar energy, and provides a photovoltaic module and a preparation method thereof. The first packaging adhesive film and the second packaging adhesive film are stacked, and a gap is formed between the first packaging adhesive film and the second packaging adhesive film; the photovoltaic module is provided with a central area and a peripheral area surrounding the central area, the battery string is located in the central area, the first packaging adhesive film of the peripheral area is provided with a first through hole, the second packaging adhesive film of the peripheral area is provided with a second through hole, the first through hole is opposite to the second through hole, and at least one of the first through hole and the second through hole is a through hole; the first through hole and the second through hole are filled with the filling structure, and in the laminating process, the cross-linking curing speed of a material forming the filling structure is higher than that of a material forming the first packaging adhesive film, and the cross-linking curing speed of the material forming the filling structure is also higher than that of a material forming the second packaging adhesive film. The embodiment of the invention is at least beneficial to improving the yield and stability of the photovoltaic module.

Description

technical field [0001] The embodiments of the present application relate to the field of solar energy, and in particular, to a photovoltaic module and a preparation method thereof. Background technique [0002] The adhesive film for encapsulation of photovoltaic modules is an important part of solar photovoltaic modules. It is located between the glass and the cells or between the cells and the backsheet. It can seal, insulate and protect the cells and improve the long-term stability of the modules. [0003] However, the packaging structure of solar photovoltaic modules has certain defects during use. For example, it is easy to cause adhesive separation between the packaging structure and solar cells or battery strings, resulting in poor stability of solar photovoltaic modules and affecting the normal use of solar cell modules. ; In addition, currently in the process of packaging solar cells or battery strings, it is not possible to quickly locate the solar cells or battery ...
