Embodiment Construction

[0041] As can be seen from the background art, the prior art faces the problem of lowering the yield of photovoltaic modules while improving the module efficiency of photovoltaic modules.

[0042] In order to improve the module efficiency of photovoltaic modules, stitch welding technology can be used to eliminate the gap between cells, that is, in the cell string of photovoltaic modules, there is an overlapping area between adjacent cells, and in this overlapping area, there are adjacent cells. The overlapping between the cells has a welding ribbon for electrically connecting the adjacent cells. In the production process of photovoltaic modules, in the lamination stage, under the action of lamination pressure, these overlapping areas have a higher risk of cracking or chipping than other areas, thus affecting the yield of the fabricated photovoltaic modules.

[0043] In order to solve the above problem, the present invention provides an adhesive film, wherein a groove is provid...

Abstract

An embodiment of the present invention provides an adhesive film, a photovoltaic module and a manufacturing method thereof. The adhesive film is used to encapsulate battery strings in a photovoltaic module, the battery string includes a plurality of battery sheets, and adjacent battery sheets have overlapping regions , the adhesive film has a first surface facing the battery string and a second surface opposite to the first surface, characterized in that it includes: at least one concave extending from the first surface to the second surface Grooves, the position of each groove is directly opposite to the position of at least one of the overlapping regions. The embodiments of the present invention help improve the yield of the photovoltaic module while improving the module efficiency of the photovoltaic module.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of solar cells, and in particular, to an adhesive film, a photovoltaic assembly and a manufacturing method thereof. Background technique [0002] With the problems of energy shortage, rising global temperature and deteriorating environment, solar energy has received more and more attention as a green and renewable energy. A photovoltaic module is a device that converts renewable solar energy into electricity. [0003] Module efficiency is an important indicator to measure the performance of photovoltaic modules, which directly reflects the utilization efficiency of photovoltaic modules for light energy. Specifically, high module efficiency is not only conducive to reducing the cost in the production process of photovoltaic modules, but also reducing the floor space required for the operation stage of the power station; in addition, under the condition that the module power of the p...
