To obtain other relevant attached drawings according to these attached drawings.
Fig. 1 is according to the structural schematic diagram of the cell piece component shown in an embodiment of the present invention, and Fig. 2 is according to this reality
With the structural schematic diagram of novel another cell piece component for implementing to exemplify, Fig. 3 is according to shown in the utility model embodiment
First busbar, 31 structural schematic diagram, Fig. 4 are according to 32 structural schematic diagram of the second busbar shown in the utility model embodiment;
As shown in Figures 1 to 4, cell piece component provided by the embodiment of the utility model, including cell piece mould group 1, encapsulated layer 2 and confluence
Item 3, the light-receiving surface side and shady face side of the cell piece mould group 1 are provided with the encapsulated layer 2.
Wherein, the busbar 3 includes the connecting pin being connected and lead end, the connecting pin and the cell piece mould group
1 electrode connection, the lead end are pierced by by the encapsulated layer 2 and are located at the outer surface of the encapsulated layer 2, the lead end with
The insulation of encapsulated layer 2 is fixed.A kind of cell piece component provided by the embodiment of the utility model, by the way that the busbar 3 is arranged
With 1 electrode of cell piece mould group, and the busbar 3 is extended and is fixed on the outside of the encapsulated layer 2, therefore described
Busbar 3 only needs to realize and connect with electrode in cell piece component internal, is not required to be arranged too long, therefore is not related to busbar
3 are built in the insulation processing and Welding Problems of cell piece component internal, easy to operate, reduce working hour and cost, and avoid welding
Jointing temp is excessively high, welding strength is excessive to damage caused by cell piece.
Simple processing is fixed and guaranteed effectively to insulate, in the cell piece component that an embodiment of the present invention provides, such as
Shown in Fig. 3 to Fig. 4, the busbar 3 has the conducting surface 301 being oppositely arranged and insulation bonding plane 302, is located at the connecting pin
The conducting surface 301 and 1 Ohmic contact of cell piece mould group, positioned at the lead end the insulation bonding plane 302 with
The outer surface of the encapsulated layer 2 is adhesively fixed.The structure of busbar 3 provided by the utility model and busbar in the prior art
3 structures are all different, and 3 one side of busbar realizes that insulation is Nian Jie with the encapsulated layer 2 in the present embodiment, and another side is carried out electricity
It is transmitted to outside.Conducting surface 301 can be tin-coated copper strip or other electrically conductive materials.
Since existing cell piece is connect outside by 3 exit of busbar after the welding of cell piece component internal again with busbar 3
Portion's terminal box, steam are easy to penetrate into the cell piece mould group 1 of cell piece component internal along 3 exit of busbar, lead to cell piece group
The reduced service life of part, cell piece component are damaged since steam invades.To solve this problem, the utility model one is implemented
In the cell piece component that example provides, waterproof layer, such as Fig. 1 are provided at the position that is pierced by the encapsulated layer 2 for the busbar 3
To shown in Fig. 2, in the place setting waterproof layer that busbar 3 is pierced by, prevent external moisture from entering in cell piece component along busbar 3
Portion, to prevent damage of the steam to cell piece.Wherein, waterproof layer can be set on encapsulated layer close to the one of cell piece mould group
The outer surface of the encapsulated layer is arranged in side and/or waterproof layer.In Fig. 1 to Fig. 2 mono- preferred example, waterproof layer is also
Back-adhesive film can be specifically located at and second blocked water between film.
In the present embodiment, the waterproof layer can be butyl rubber 4, and surrounding of the busbar 3 at 2 place of being pierced by of encapsulated layer posts fourth
Base rubber 4, the width of butyl rubber 4 can take the circumstances into consideration to select, be advisable with playing resistance effect and not influencing cell piece component package simultaneously.If
Be equipped with butyl rubber 4 cell piece component it is laminated after, opening position of the busbar 3 on encapsulated layer 2 can be blocked by excessive glue mode
It sets, promotes anti-steam infiltration capacity.
When steam is want to penetrate into component internal from busbar 3, steam must be into 4 layers of butyl rubber of one fixed width and thickness excessively
After get to cell piece, the settings of the waterproof layers such as butyl rubber 4 can effective blocking water vapor performance so that steam is along busbar 3
The difficulty set into cell piece component internal greatly increases, and the degree that cell piece component is encroached on by steam reduces, cell piece component
Service life be improved.

Or shown in Fig. 4;Second busbar 32 has the second connection end 321 connecting with the cathode of the cell piece mould group 1, and
Second busbar 32 extends the second lead end 322 in the outer surface of the encapsulated layer 2, as shown in Fig. 4 or Fig. 3.It is described
First busbar 31 and second busbar 32 can bend under external force and be pasted onto the outer surface of encapsulated layer 2
On, alternatively, first busbar 31 and second busbar 32 may be configured as successively three parts connected vertically.
It wherein, is easy to process and external cabling, preferably by the output end at the first lead end 312 and described second
The output end of lead end 322 is located at the same end of the cell piece mould group 1, the in this way output end of the busbar 3 of connection positive and negative anodes
The same end of cell piece component can be located at, convenient for the terminal box of end connection herein.
In the present embodiment, the connecting pin of two busbars 3 can be connect with the electrode with spot welding, can also directly according to
Cell piece component package process is relied to connect connecting pin with electrode.
The cell piece component that an embodiment of the present invention provides, the envelope of the 1 light-receiving surface side of cell piece mould group
Dress layer 2 includes that preceding glue film and first block water film, and the encapsulated layer 2 of the 1 shady face side of cell piece mould group includes back-adhesive film
And second block water film, the cell piece mould group 1 is between the preceding glue film and the back-adhesive film, the preceding glue film and the back
Glue film is POE (the pungent dilute copolymer of ethylene -) glue film.
In above-described embodiment, the cell piece mould group 1 is in series or in parallel to form by copper indium gallium selenium solar cell piece.
Cell piece component provided by the utility model, has the following technical effect that
Busbar 3 is provided with butyl rubber 4 in 2 place of being pierced by of encapsulated layer, promotes the energy that anti-steam penetrates into cell piece component internal
Power, to promote the service life of cell piece component;
