Embodiment
The present invention provides a kind of solar components to solve the above problems.Fig. 1 is the vertical view of the solar components of the present invention
Figure；Fig. 2 is the phantom of the solar components of the present invention.Referring to Fig. 1 and Fig. 2, emphasis of the invention exists
In：It is installed on by by terminal box 5 in front glass panel 1, the risk that terminal box 5 comes off in use can be reduced.Separately
Outside, because front and rear glass size is inconsistent (back of the body glass plate 4 be more than front glass panel 1), to the shadow of front glass panel 1 during installation
Sound is smaller.
Specifically, the present invention provides a kind of solar components, and it includes：One front glass panel 1；One back of the body glass plate 4；
One solar battery sheet 3, it is between front glass panel 1 and back of the body glass plate 4；One the first encapsulating material layer of printing opacity 2, its
Between front glass panel 1 and solar battery sheet 3；And a terminal box 5, it is installed in front glass panel 1, wherein before
Glass plate 1 forms through a hole knockout or all crescent mode Precision Machinings, in order to which terminal box 5 is installed on into preceding glass
In glass plate 1.Terminal box 5 is mountable to the periphery or centre position of front glass panel 1, and solar battery sheet is arrived without covering
3, its particular location can be depending on the outlet position of the actual typesetting of solar battery sheet 3.
The side of front glass panel 1 is incidence surface, and sunshine injects solar battery sheet inside from the incidence surface of front glass panel 1
3.Solar battery sheet 3 can be any existing solar battery sheet；For example, solar battery sheet 3 can include more
Individual electrode layer or photoelectric conversion layer, to receive luminous energy and change luminous energy as electric energy, it will not be repeated here.
In the present embodiment, front glass panel 1 is 0.5mm to 4mm safety glass, and back of the body glass plate 4 is 0.5mm to 6mm
Safety glass or more than 6mm simple glass, and carry on the back glass plate 4 size be more than front glass panel 1 size, have more
The width come is depending on the size of installation tool, but width have to be larger than 5mm, in order to install solar components and right
The influence of front glass panel 1 is smaller.
In another embodiment, front glass panel and/or the material for carrying on the back glass plate can be simple glass, safety glass or saturating
Ming tree fat.On the selection of material, light transmittance energy that the light transmittance of 2mm common float glass is about 90%, 1.2mm
Reach 91%, pattern glass can improve about 1% light transmittance.If coating antireflective film again, light transmittance can be further added by 2%,
So patterned coated glass can increase by 3% light transmittance than common float glass.So in order to improve solar components
Generating efficiency, in another embodiment, front glass panel 1 can use embossing plated film safety glass.
In another embodiment, one second encapsulating material layer 2' can be included between back of the body glass plate 4 and solar battery sheet 3.
Encapsulating material layer 2,2' at least one can include (but being not limited to) polyvinyl butyral (PVB), ethene vinegar
The material such as vinyl acetate (EVA) or transparent polymer insulation glue material.
If front glass panel 1 forms dry hole 7 through perforate, the diameter in hole 7 is 10mm to 16mm, the center of holes 7
Away from least 20mm.In addition, front glass panel 1 can form a circular arc through cutting crescent mode in the periphery of front glass panel 1
(not shown), the depth bounds of circular arc is 30mm to 35mm (being preferably 35mm), and the width range of circular arc is
155mm to 165mm (preferably 162mm).In order to which terminal box 5 to be installed on to the front of solar components, busbar
6 (being electrically connected with solar battery sheet 3) are drawn from the hole 7 of front glass panel 1 or circular arc and are connected to terminal box 5.
Front glass panel 1 and back of the body glass plate 4 can be handled through glass tempering processing method so that front glass panel 1 and back of the body glass plate 4
Surface stress be higher than 40MPa.Specifically, glass tempering processing method includes physical toughened and chemical tempering.Physics
Tempering is to form tensile stress by heat-treating methods glass surface, strength of glass is improved, after physical toughened
Glass surface stress can reach 40-180MPa；Chemical tempering is then to change glass surface component by chemical method, together
Sample is to increase surface stress, and the glass surface stress after chemical tempering can reach 200-750MPa.
In another embodiment, back of the body glass plate 4 can plate colorful colorant film on its surface, such as white,
Black or blueness etc., the effect of enabling solar components to increase color diversity.In this embodiment, the second encapsulation
Material layer 2' also must printing opacity.
The present invention has unexpected effect：In existing component, terminal box is mounted to module backside (back of the body glass
Glass plate), this structure causes terminal box to have the risk to come off.The present invention by terminal box 5 by being installed on solar components
Front (in front glass panel 1) to avoid terminal box 5 from coming off the problem of；Simultaneously the surface of glass plate 4 is carried on the back to plate with color
Colorant film, solar components is increased color diversity.
The specific embodiment explanation of the present invention is as above.However, can still there are other modifications.Therefore, people in the art
Member under the premise of without departing from the spirit of the present invention, can also make various modifications and retouching to it, any modification and
Retouching still belongs to the protection domain that the present invention is defined.
