It is described more fully the exemplary embodiment of the disclosure below with reference to accompanying drawings.Although showing this public affairs in attached drawing
The exemplary embodiment opened, it being understood, however, that may be realized in various forms the disclosure without the implementation that should be illustrated here
Example is limited.On the contrary, these embodiments are provided to facilitate a more thoroughly understanding of the present invention, and can be by the model of the disclosure
It encloses and is fully disclosed to those skilled in the art.
As shown in Figure 1, the embodiment of the invention provides a kind of solar battery mould group, which includes:
Solar battery group 102, glue film 103, the upper encapsulated layer 101 with setting curve form and at least one lower envelope
Fill backboard 104；
Wherein, the quantity of the lower packaging back board 104 is determined according to the radius of curvature of the curve form；
The solar battery group 102 is laid on the upper encapsulated layer according to the curve form by the glue film 103
Between 101 and at least one described lower packaging back board 104, and the laying area of at least one lower packaging back board 104 is little
In the surface area of the upper encapsulated layer 101.
Embodiment according to figure 1, which includes solar battery group, glue film, curve form
Upper encapsulated layer and one or more lower packaging back boards.The quantity of lower packaging back board is determined according to the radius of curvature of curve form
Out.Solar battery group is laid between upper encapsulated layer and each lower packaging back board by glue film according to curve form, and
Each lower packaging back board be laid with area no more than upper encapsulated layer surface area (surface area can in upper encapsulated layer with the sun
Can battery pack be in contact the surface area of side.Such as the surface area phase of the laying area and upper encapsulated layer of each lower packaging back board
Together, or, the surface area for being laid with area and being slightly smaller than upper encapsulated layer of each lower packaging back board).By above-mentioned it is found that lower packaging back board
Quantity be determined according to the radius of curvature of curve form, therefore when the radius of curvature of upper encapsulated layer is smaller (for example,
Minimum profile curvature radius is 600mm or 600mm or more) can also mat formation each lower packaging back board on upper encapsulated layer, so that
Solar battery mould group can mat formation in radius of curvature smaller (for example, minimum profile curvature radius is 600mm or 600mm or more)
On curved surface.Therefore, the song that solar battery mould group can be small in radius of curvature may be implemented in scheme provided in an embodiment of the present invention
It is laid on face.
In an embodiment of the invention, Fig. 1 illustrate only include two lower packaging back boards part solar battery
Mould group.
In an embodiment of the invention, the curve form of upper encapsulated layer will be with the curve form phase one of object to be laid
It causes.For example, the curve form of solar battery mould group will be with the curve form of roof when object to be laid is the roof of vehicle
It is consistent, so that solar battery mould group and the compactness of roof are higher.
In this embodiment, it is preferred that the minimum profile curvature radius of the upper encapsulated layer of curve form is greater than or equal to 600mm.
In an embodiment of the invention, the radius of curvature of the quantity of the lower packaging back board 104 and the curve form
Between meet:
The quantity of the lower packaging back board 104 is reduced with the increase of the smallest radius of curvature in the curve form.
In the present embodiment, the smallest radius of curvature more hour illustrates that curved surface is steeper in curve form.It is steeper in curved surface
When need to increase the quantity of lower packaging back board, can reduce the Curvature varying on single lower packaging back board when mating formation in this way, from
And reduce the probability that fold or undaform lines are formed on lower packaging back board.
In an embodiment of the invention, in the number according to radius of curvature the smallest in curve form packaging back board under determining
When amount, the relationship between the quantity of the lower packaging back board 104 and the radius of curvature of the curve form includes at least following two
Kind situation:
Situation one: in an embodiment of the invention, the quantity of the lower packaging back board 104 and the song of the curve form

Wherein, the N characterizes the quantity of the lower packaging back board；The RminCharacterize the smallest song in the curve form
Rate radius, unit mm.
In the present embodiment, the lesser curved surface of radius of curvature is usually the steeper curved surface of the gradient.In the steeper curved surface of the gradient
When the biggish lower packaging back board of middle laying area, lower packaging back board usually will form fold or undaform lines.And these pleats
Wrinkle or undaform lines usually easily cause bubble in solar battery mould group, and perhaps hollowing bubble or hollowing will reduce too
The reliability and safety of positive energy battery modules.
In the present embodiment, it in order to reduce the probability that fold or undaform lines occurs in lower packaging back board, needs to obtain
Each radius of curvature included by upper encapsulated layer.Then more each radius of curvature, and find out wherein the smallest radius of curvature.So
Afterwards according to the size of minimum profile curvature radius, the quantity of lower packaging back board is determined.As can be seen that equation group from equation group (1)
(1) it is suitable for the case where minimum profile curvature radius is greater than or equal to 600mm.It, can when minimum profile curvature radius is greater than or equal to 600mm
Directly to determine the quantity of lower package board according to equation group (1).
In the present embodiment, when radius of curvature is greater than or equal to 600mm, minimum profile curvature radius is bigger, lower packaging back board
Quantity it is fewer.
For example, then determining lower envelope according to equation group (1) when determining that the smallest radius of curvature is 750 in curve form
Fill the quantity 5 of backboard.
Situation two: in an embodiment of the invention, the quantity of the lower packaging back board 104 and the song of the curve form

When splice point between backboard, it can determine that the quantity of lower packaging back board is 2.It needs to reduce to greatest extent in lower packaging back board
When the probability of existing fold or undaform lines, it can determine that the quantity of lower packaging back board is 4.
It can be true according to minimum profile curvature radius when minimum profile curvature radius is greater than or equal to 600mm according to above-described embodiment
Make the quantity of lower packaging back board.Therefore when minimum profile curvature radius is greater than or equal to 600mm, mat formation and minimum profile curvature radius
The probability to form fold or undaform lines can be reduced when packaging back board under the quantity to match, to improve the sun
The reliability and safety of energy battery.
In an embodiment of the invention, the quantity of the lower packaging back board 104 is according to the smallest in the curve form
Radius of curvature and maximum radius of curvature determine.
In the present embodiment, the maximum curvature radius in curve form and when the bigger difference of minimum profile curvature radius, explanation
The slope change of curve form is bigger.It therefore can be true according to radius of curvature the smallest in curve form and maximum radius of curvature
The quantity of packaging back board is fixed, to reduce each lower corresponding Curvature varying range of packaging back board when mating formation.
In an embodiment of the invention, the radius of curvature of the quantity of the lower packaging back board 104 and the curve form
Between meet formula (1)；
