Battery manufacturing process, reduces the consumption of silicon.
Description of the drawings
Fig. 1 is the structure diagram for the solar cell module that specific embodiment of the present invention provides；
Fig. 2 is the structural representation of the composite battery group for the solar cell module that specific embodiment of the present invention provides
Figure.
Specific embodiment
Further illustrate the technical solution of the utility model below with reference to the accompanying drawings and specific embodiments.
Please refer to Fig.1 with shown in 2, the present embodiment provides a kind of solar cell module, including stacking gradually from bottom to top
Backsheet layer 1, encapsulation glue-line 2 and photic zone 3, wherein, encapsulate in glue-line 2 and be provided with composite battery group 4, composite battery group 4 is wrapped
Battery installing plate 5 is included, battery installing plate 5 includes several grooves and boss being intervally arranged, and groove is in outside diffusion type, each recessed
The bottom of slot is provided with crystal-silicon battery slice 6, and hull cell piece 7 is provided on each boss.By crystal-silicon battery slice 6 and hull cell
Piece 7 is applied in combination, you can the characteristics of embodying 6 high-conversion rate of crystal-silicon battery slice, it also can be excellent by force by 7 dim light of hull cell piece
Gesture improves the performance of integral battery door component.
In the present embodiment, the angle that two oblique side walls of groove are formed is 80 degree, is provided on the oblique side wall of each groove
Reflector 8, effective reflecting condensation is in crystal-silicon battery slice 6.
Backsheet layer 1 generally using ageing-resistant materials such as TPT, TPE, plays sealing, insulation, waterproof action.
Photic zone 3 is generally using ultrawhite tempered glass of the light transmittance more than 90%, to protect composite battery group 4.
Encapsulation glue-line 2 generally using EVA come tempered glass, composite battery group 4 and backboard is adhesively fixed, it is necessary to pay attention to
It is that the quality of transparent EVA material directly influences the service life of component, if EVA gumminesses are not up to standard, EVA and tempered glass, backboard
Adhesive strength is inadequate, can all EVA be caused to do sth. in advance aging, influence assembly life-span.
Filter layer 9 is generally additionally provided between encapsulation glue-line 2 and photic zone 3 so that the opto-electronic conversion effect of composite battery group 4
Rate is not easily susceptible to the influence of temperature change, contributes to the promotion of the operational stability and service life of solar battery apparatus.
Finally, after 4 wiring of composite battery group, with aluminum alloy frame fixation kit, gap location uses silica gel sealing.
In conclusion the solar cell module in the present embodiment crystal-silicon battery slice and hull cell piece are passed through it is concavo-convex
It is intervally arranged, by the way of groove optically focused, further improves the optoelectronic transformation efficiency of crystal-silicon battery slice, the thin-film electro of this outer lug
