Problems solved by technology

However, in addition to the heat and humidity test, solar modules also undergo a number of other inspections, such as: appearance defects, electrical connections, and whether there are bubbles in the packaging material. Solar modules that are judged to be of poor quality are usually reworked
In the rework process, the solar module needs to be heated and the back sheet is torn off for component replacement, but often the back sheet and the solar module are too tightly bonded to each other, causing damage to the solar cells during tearing. Thus, the rework cannot be successfully completed
However, solar modules using polyolefin as the encapsulant material will cause more serious damage to the solar cells when the backsheet is torn off than solar modules using EVA as the encapsulant material, and the rework yield rate is lower

Embodiment Construction

[0042] Detailed descriptions of embodiments of the present invention are set forth below, however, the present invention can be practiced broadly in other embodiments than these detailed descriptions. That is to say, the scope of the present invention is not limited by the proposed embodiments, but should be based on the patent scope of the present invention.

[0043] see image 3 , is an embodiment of the present invention. image 3 and figure 2 The same is the cross-sectional view of the solar module, but there are differences in the laminated structure. The solar module 31 of the present invention has a layer of substrate 32 and a layer of back sheet 34, and there is a layer between the substrate 32 and the back sheet 34. A plurality of solar cells 33, in order to make the above elements can be combined smoothly, so a layer of first packaging material 35 is filled between the substrate 32 and the plurality of solar cells 33, and correspondingly, the plurality of solar ce...

Abstract

The invention discloses a solar energy module which increases reliability of wet-thermal test and improves rework yield. The solar energy module comprises a substrate, a first package material layer, at least one solar cells, a second package material layer, a buffer material and a back board. When the module is reworked, damage due to external force on the solar cells is effectively reduced, thus improving rework yield.

Description

technical field [0001] The invention relates to a solar module, in particular to a package structure of the solar module, and a manufacturing method and a rework method of the module structure. current technology [0002] see figure 1 , figure 1 It is a top view of an existing solar module 11. Generally speaking, the front of the solar module 11 is a light-receiving surface for receiving sunlight during the day, so the uppermost layer of the front of the solar module 11 is usually made of transparent The glass substrate 12 is combined, and through the glass substrate 12 we can clearly see the array composed of a plurality of solar cells 13 located under the glass substrate 12; in addition, to meet customer and product requirements, in the solar module 11 It is also possible to configure only one solar cell. The plurality of solar cells 13 are electrically connected to each other and neatly arranged in several strings, and each string of solar cells of the plurality of sol...
