The present disclosure provides a package assembly, comprising: the first package plate, the second package plate and the support.

The first packaging plate and the second packaging plate are oppositely arranged, the supporting piece is arranged between the first packaging plate and the second packaging plate, the supporting piece contacts and supports the first packaging plate and the second packaging plate, a packaging area for installing the functional piece is enclosed among the supporting piece, the first packaging plate and the second packaging plate, and one side surface of the functional piece, which is close to the second packaging plate, is non-adhered to the second packaging plate. The functional element may be a solar cell.

The package assembly provided by the present disclosure includes a first package plate, a second package plate, and a support. The supporting piece is arranged between the first packaging plate and the second packaging plate, and the supporting piece contacts and supports the first packaging plate and the second packaging plate, and the supporting piece, the first packaging plate and the second packaging plate enclose a packaging area for installing the functional piece, so that the functional piece is close to one side surface of the second packaging plate and can be non-adhered to the second packaging plate.

In this application, this encapsulation subassembly is at the in-process of pressfitting, and support piece can play the cushioning effect to thereby avoid the function piece directly to bear the fracturing problem that leads to. The support can also be supported to secure the first package plate and the second package plate during actual use, thereby keeping the device structure stable.

Compared with the packaging assembly in the prior art, the packaging assembly can enable the functional piece to be far away from one side surface of the second packaging plate and the second packaging plate to be in non-adhesion arrangement, so that the functional piece is easy to separate from the second packaging plate, and the disassembling difficulty of the packaging assembly in the recycling factory returning treatment process can be effectively reduced. Further, the support piece is additionally arranged between the first packaging plate and the second packaging plate in the packaging assembly, the first packaging plate and the second packaging plate are supported through the support piece and enclose a packaging area, and structural stability of the assembly in the pressing process and subsequent use can be maintained while one side surface of the functional piece, which is close to the second packaging plate, is not adhered to the second packaging plate.

Further, the disclosure also provides a photovoltaic module, which includes the solar cell and the packaging module in the above embodiment, where the solar cell is a functional element disposed in a packaging region of the packaging module. In order to facilitate understanding of the package assembly and the photovoltaic assembly provided by the present disclosure, the description below is mainly made by the structure of the photovoltaic assembly, and it is understood that the photovoltaic assembly includes the package assembly.

Fig. 1 shows a schematic longitudinal cross-sectional structure of a photovoltaic module according to the present disclosure. Referring to fig. 1, the photovoltaic module includes a first package plate 110, a second package plate 120, a solar cell 130, and a support 140. The first package plate 110 and the second package plate 120 are disposed opposite to each other, the supporting member 140 is disposed between the first package plate 110 and the second package plate 120, and the supporting member 140 contacts and supports the first package plate 110 and the second package plate 120, the supporting member 140, the first package plate 110 and the second package plate 120 enclose a package region 131, the solar cell 130 is disposed in the package region 131, and a side surface of the solar cell 130, which is close to the second package plate 120, is non-adhered to the second package plate 120.

The solar cell 130 is arranged in the packaging area 131 of the packaging component as a functional piece, and the solar cell 130 is arranged between one side surface of the second packaging plate 120 and the second packaging plate 120 in a non-adhesive mode, so that the photovoltaic component can be separated from the solar cell 130 only by disassembling the second packaging plate 120 and the supporting piece 140 in the recycling factory returning treatment process, and the disassembling difficulty of the photovoltaic component can be effectively reduced.

It is understood that the non-adhesion of the solar cell 130 to the second package plate 120 near one side surface of the second package plate 120 means that: the solar cell 130 is not directly adhered to each other, nor is it indirectly adhered by a material having an adhesive property between a side surface of the solar cell 130 adjacent to the second package plate 120 and the second package plate 120. For example, the side surface of the solar cell 130 near the second package plate 120 has no adhesion with the interface between the contact and the second package plate 120; as another example, a side surface of the solar cell 130 adjacent to the second package plate 120 is spaced apart from the second package plate 120, and there may be no filler or filler but the filler is not adhesive. It is also understood that other areas of the solar cell 130 than the side surface may be adhered to the second package plate 120 by indirect bonding, e.g., the side surface of the solar cell 130 may be adhered to the support 140, and the support 140 may be adhered to the second package plate.

Referring to fig. 1, in some examples of this embodiment, a side surface of the solar cell 130 adjacent to the second package plate 120 is spaced apart from the second package plate 120. This enables the second package plate 120 not to directly contact the side surface of the solar cell 130 close to the second package plate 120, avoiding the problem of fracturing due to the second package plate 120 directly contacting the solar cell 130.

Referring to fig. 1, in some examples of this embodiment, the solar cell 130 is fixedly disposed with respect to the support 140, and a surface of the support 140 adjacent to the second package plate 120 protrudes from a side surface of the solar cell 130 adjacent to the second package plate 120 such that a gap 132 is provided between the side surface of the solar cell 130 adjacent to the second package plate 120 and the second package plate 120.

It can be appreciated that, since the solar cell 130 is fixedly disposed relative to the support 140, the second package board 120 is blocked by the support 140 and cannot contact the solar cell 130, such that a gap 132 is formed between a side surface of the solar cell 130 adjacent to the second package board 120 and the second package board 120. The gap 132 is formed in such a manner that it is supported by the support 140 to avoid or reduce the introduction of other filler materials, which not only simplifies the structure of the photovoltaic module, but also reduces the attenuation of light.

Referring to fig. 1, in some examples of this embodiment, the spacing d of the gap 132 may be controlled to be 0.1mm to 1mm, and the gap 132 provides a certain deformation margin or tolerance margin for each component, avoiding the problem of fracturing due to local deformation of the second package plate 120 or the solar cell 130, etc.

In some examples of this embodiment, gap 132 is a negative pressure gap. It is understood that a negative pressure gap refers to a pressure in the gap 132 that is below atmospheric pressure. In some examples of this embodiment, the air pressure in the negative pressure gap may be less than or equal to 1000Pa. By providing the negative pressure gap, the first package plate 110 and the second package plate 120 can be naturally combined with the support 140 more tightly under the action of the atmospheric pressure, thereby improving the stability of the device structure.

Referring to fig. 1, in some examples of this embodiment, the photovoltaic module further includes a first adhesive member 151, the first adhesive member 151 is disposed within the encapsulation region 131, and the first adhesive member 151 is adhered to an inner wall of the support 140 and a side surface of the solar cell 130. The solar cell 130 is adhered to the support 140 through the first adhesive member 151, so that the position of the solar cell 130 can be fixed in an auxiliary manner, and the structural stability of the photovoltaic module can be improved.

Fig. 2 shows a schematic cross-sectional view of the support 140 of fig. 1. Referring to fig. 2, the supporting member 140 may have a hollow cylindrical structure, and it is understood that the hollow cylindrical supporting member 140 can be separated into an inner area and an outer area, and the encapsulation area 131 is located in the inner area of the hollow cylindrical supporting member 140.

In some examples of this embodiment, the first adhesive 151 is adhered to the inner wall of the support 140.

Referring to fig. 1, in some examples of this embodiment, the photovoltaic module further includes a second adhesive 152. The second adhesive 152 is disposed in the encapsulation area 131, the second adhesive 152 is adhered to the first encapsulation plate 110, and the second adhesive 152 is located between the first encapsulation plate 110 and the solar cell 130, and the solar cell 130 is adhered to the first encapsulation plate 110 through the second adhesive 152. The second adhesive 152 can fixedly adhere the solar cell 130 to the first package board 110, and can reduce the influence caused by the change of the component structure by using the current production equipment and production method. It will be appreciated that the solar cell 130 can be separated by only removing the second package plate 120 during the removal process, so that the solar cell 130 is kept adhered to the first package plate 110 without significantly affecting the removal difficulty.

Referring to fig. 1, in some examples of this embodiment, the first adhesive member 151 is connected to the second adhesive member 152 to make the structure of the photovoltaic module more stable. Further, the first adhesive member 151 and the second adhesive member 152 may be an integrated adhesive film. The portion of the integrated adhesive film between the support 140 and the solar cell 130 may serve as a first adhesive member 151, and the portion thereof between the first package plate 120 and the solar cell 130 may serve as a second adhesive member 152.

Referring to fig. 1, in some examples of this embodiment, the photovoltaic module further includes a fixture 160. The fixing member 160 is disposed around the first package plate 110, the second package plate 120 and the supporting member 140, and the fixing member 160 is further coated onto opposite surfaces of the first package plate 110 and the second package plate 120. By providing the fixing member 160 and restricting the supporting member 140 between the first package plate 110 and the second package plate 120, the supporting member 140 is prevented from being deformed outward during the lamination process, which can keep the positions of the supporting member 140 and the solar cell 130 from being substantially shifted during the lamination process. The material of the fixing member 160 may be metal, such as iron, copper, aluminum, or an alloy thereof.

Referring to fig. 1, in some examples of this embodiment, the support 140, the first package plate 110, and the second package plate 120 cooperate such that the enclosed package area 131 is a closed space. It will be appreciated that the cooperation of the support 140, the first package plate 110 and the second package plate 120 may be: the first package plate 110 and the second package plate 120 close the support 140 from the top and bottom, respectively, such that the inner region of the support 140 is insulated from the outer region. By means of the supporting member 140 enclosing a closed space with the first package plate 110 and the second package plate 120, contaminants such as water vapor can be prevented from penetrating into the interior of the assembly, and long-term effectiveness of the assembly can be maintained.

In some examples of this embodiment, the support 140 may be adhered to the first package plate 110 and the second package plate 120.

In some examples of this embodiment, the support 140 may include a hot melt adhesive strip or a rubber strip in order to provide better adhesion and air tightness.

In this embodiment, the solar cell 130 in the photovoltaic module is a solar cell. The solar cell may include one or more battery pieces, and the plurality of battery pieces may be arranged to form a plurality of battery strings.

It can be appreciated that, in the photovoltaic module shown in fig. 1, the removal of the solar cell 130 therein forms a packaging module, and the packaging module can be applied to not only packaging of the solar cell, but also packaging of other devices, so as to reduce the difficulty of disassembling the devices.

The photovoltaic module is introduced into the supporting piece 140 and one side adhesive film in the traditional technology is removed, separation between the second packaging plate 120 and the solar cell can be avoided under the condition that the packaging reliability of the photovoltaic module is kept, the disassembly difficulty of the module in the recycling factory returning treatment process is effectively reduced, and the disassembly efficiency and the recycling benefit of the module are improved.

In addition, in some specific examples, due to the elimination of the large area of the adhesive film between the second package plate 120 and the solar cell, a certain material cost is saved, for example, for an area of about 1.96m ² The photovoltaic module of the (2) can save 15 yuan material cost approximately.

Moreover, in some specific examples, the maximum power attenuation of the photovoltaic module is also generally reduced during some testing procedures. Specific results can be seen in table 1 below.
