At present, the used cell piece of common solar energy crystal silicon and amorphous silicon cell component all is that single face is subjected to light generating battery sheet, and its corresponding packaged type also is the single face transparent enclosure.In order to reduce solar module to the needs of erection space, improve the generating efficiency of solar cell, the double-sided solar battery assembly has appearred.
In order to utilize two-sided light, assembly will be designed to the both sides transparent configuration, mainly contains at present glass+transparent back panel, and two kinds of structures of glass+glass.From alleviating the weight of assembly, the assembly weight of the first structure is lighter, and its application space is also more extensive.But in the existing technique, in order to prevent the xanthochromia of transparent back panel, the encapsulating material on its two sides all adopts the encapsulating material of ultraviolet cut-on.Along with the progress of cell piece technology, increased its generating capacity at ultraviolet band, in order to give full play to the generating capacity of battery, prevent again the xanthochromia of backboard simultaneously, be necessary to design a kind of novel solar battery assembly that rationally utilizes ultraviolet light.
In addition, existing technique, its terminal box are directly installed on the backboard of assembly mostly, and the cell backside that not only weakens its covering place is subjected to luminous energy power, also can produce the hot spot phenomenon simultaneously, has reduced the actual life of assembly.
Summary of the invention
The utility model purpose provides a kind of double-sided solar battery assembly.
For achieving the above object, the technical solution adopted in the utility model is: a kind of double-sided solar battery assembly, comprise successively from top to bottom glass, upper strata glued membrane, cell piece group, lower floor's glued membrane and transparent back panel, also comprise frame and terminal box, described upper strata glued membrane is the high thoroughly packaging adhesive film of ultraviolet light, and described lower floor glued membrane is ultraviolet light cut-off glued membrane; Described terminal box is located at the side of frame.
Above, the high thoroughly packaging adhesive film of described ultraviolet light can adopt existing commercial goods, such as the F406 glued membrane of Hangzhou Foster photovoltaic material limited company production; Described ultraviolet light cut-off glued membrane can adopt existing commercial goods, such as the F806 glued membrane of Hangzhou Foster photovoltaic material limited company production.Preferably, described up and down glued membrane is the combination of ultraviolet light high transmission EVA and ultraviolet light cut-off EVA.
Cell piece in the described cell piece group can adopt generating electricity on two sides single crystal battery or generating electricity on two sides polycrystalline battery, can use between the cell piece to be pressed in advance the curved welding of Z-type and to connect.
Described transparent back panel can adopt the structures such as transparent TPT, transparent TPE, transparent KPK, transparent KPE, transparent PET.Preferably, described backboard is transparent TPE structure.
In the technique scheme, described frame is the composite material frame.
Preferably, described frame is the polyurethane frame.
In the technique scheme, a side of described frame is provided with through hole, and the convergent belt of cell piece group is electrically connected with terminal box by through hole.I.e. perforate on one of them short frame of frame, above-mentioned cell piece assembly welding is connected to convergent belt, by perforate on the frame, convergent belt is linked to each other with terminal box, and terminal box is installed on the assembly one side short frame.
Because technique scheme is used, the advantage that the utility model compared with prior art has is:
1, the utility model design has obtained a kind of new double-sided solar battery assembly, used ultraviolet light can see through packaging adhesive film in the assembly front, increased the ultraviolet light of front illuminated to the battery, the power output of front assembly has promoted more than 1.5%, and then has relatively reduced the installing space in same power power station.
2, the utility model has used the composite material frame, such as the polyurethane frame, because the polyurethane frame has good salt spray resistance, chemical-resistance, improved the reliability of assembly, avoided simultaneously use aluminium matter frame and caused abroad to the antiduping threat of China's metallic article; And reduced production cost, alleviated the weight of assembly, reduced the requirement to system's mounting bracket.
3, the utility model is located at terminal box the side of frame, not only is conducive to the heat radiation of terminal box, and greatly reduce the blocking of assembly back side light, avoided the generation of hot spot phenomenon, increased the actual life of assembly.
4, the utility model is simple in structure, is convenient to preparation, and has good operability, practicality, is suitable for applying.
