Description

A kind of solar cell module
Technical field
The utility model is related to technical field of solar batteries more particularly to a kind of solar cell modules.
Background technology
With concern of the mankind to environmental protection, solar energy is received more and more attention and used as a kind of green energy resource, It has been increasingly becoming one of main energy.Solar cell module is also solar panel, is that a kind of utilization opto-electronic conversion is imitated The device of electric energy should be converted the solar into, is the core in solar power system.
The solar cell of mainstream has crystal silicon solar batteries and thin-film solar cells (non-crystalline silicon), the crystal silicon sun at present The advantage of energy battery is high conversion efficiency, sturdy and durable, but production technology is more complicated, and cost of manufacture is very big, and dim light is poor.And The advantages of thin-film solar cells is simple production process, and silicon materials consumption is seldom, and dim light is good, but photoelectric conversion efficiency is inclined Low, same size takes up an area big.
Therefore for the research and development of current solar cell, high transformation efficiency how not only can guarantee, but also can reduce cost, It is this field urgent problem to be solved.
Utility model content
The purpose of this utility model is to provide a kind of solar cell module, with reference to above-mentioned crystal silicon, non-crystal silicon solar energy The quality of battery, learns from other's strong points to offset one's weaknesses, and on the basis of current solar cell, improves electricity conversion, reduces manufacture cost.
For this purpose, the utility model uses following technical scheme:
A kind of solar cell module, including backsheet layer, the encapsulation glue-line and photic zone stacked gradually from bottom to top, In, it encapsulates and composite battery group is provided in glue-line, composite battery group includes battery installing plate, and battery installing plate includes several intervals The groove and boss of arrangement, groove are in outside diffusion type, and the bottom of each groove is provided with crystal-silicon battery slice, is set on each boss It is equipped with hull cell piece.Crystal-silicon battery slice and hull cell piece are applied in combination, you can embody crystal-silicon battery slice high-conversion rate Feature by the strong advantage of hull cell piece dim light, can also improve the performance of integral battery door component.
Wherein, it is provided with reflector on the oblique side wall of each groove.Effective reflecting condensation is in crystal-silicon battery slice.
Wherein, the angle that two of groove oblique side walls are formed is less than 90 degree.More reasonably optically focused.
Wherein, encapsulate glue-line and photic zone is additionally provided with filter layer.
The beneficial effects of the utility model are, compared with prior art, the solar cell module is by crystal-silicon battery slice It is intervally arranged with hull cell piece by concavo-convex, by the way of groove optically focused, further improves the photoelectricity of crystal-silicon battery slice The defects of conversion ratio, the hull cell piece of this outer lug is compensated on crystal-silicon battery slice dim light, while simplify to a certain extent 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 The defects of pond piece is compensated on crystal-silicon battery slice dim light, while battery manufacturing process is simplified to a certain extent, reduce silicon Consumption.
Above example is to elaborate the basic principle and characteristic of the utility model, and the utility model is from above-mentioned example Limitation, on the premise of not departing from the spirit and scope of the utility model, the utility model also has various changes, these changes Change and change and both fall in claimed the scope of the utility model.The utility model requires protection scope will by appended right Ask book and its equivalent thereof.
