Film, backboard generally select white or black macromolecule organic material.Photovoltaic module receives sunlight by solar battery sheet will
Solar energy is converted to electric energy, and solar battery sheet has its distinctive temperature characterisitic, i.e., with the raising of temperature, by solar energy
Being converted to the transfer efficiency of electric energy can decline therewith, and generated energy can also decline therewith.Photovoltaic module is surveyed under full power condition
The operating temperature of examination is referred to as nominal operating temperature, and the standard operating temperature is lower more advantageous to photovoltaic module power generation, therefore such as
The nominal operating temperature what reduces photovoltaic module is the research emphasis of this field.
Utility model content
The purpose of this utility model is to provide a kind of photovoltaic modulies of low nominal operating temperature.
The purpose of this utility model adopts the following technical scheme that realization：
A kind of photovoltaic module includes the coated glass set gradually downwards from light, transparent hot melt layer, cell piece
Layer, multiple white hot melt adhesive filler strips, black hot melt adhesive layer and black backboard, the battery lamella include multiple be arranged
Cell piece, forms gap between each cell piece, and each white hot melt adhesive filler strip is located at the gap of each cell piece.
Further, the width of the white hot melt adhesive filler strip less times greater than gap between each cell piece width,
So that the gap between each cell piece is completely covered, while the white hot melt adhesive filler strip being avoided to stop heat from institute
It states cell piece and is diffused into the black hot melt adhesive layer.
Further, the photovoltaic module further includes the terminal box that is arranged on the black backboard and be arranged described
The aluminium frame of photovoltaic module surrounding.
Further, the battery lamella further includes by the welding of each cell piece electrical connection and by welding head
The convergent belt of tail both ends electrical connection.
Compared with prior art, the beneficial effects of the utility model are：Compared with prior art, the utility model photovoltaic group
The black hot melt adhesive layer and black backboard good heat dissipation effect of part, it is advantageous to reduce the operating temperature of component, namely reduce photovoltaic group
The nominal operating temperature of part；In addition white hot melt adhesive filler strip prevents light to be mapped to black hot melt adhesive layer, and light can also be made secondary
It is reflected on cell piece, further improves the efficiency of photovoltaic module.

Specific implementation mode
In the following, in conjunction with attached drawing and specific implementation mode, the utility model is described further, it should be noted that
Under the premise of not colliding, it can be formed in any combination between various embodiments described below or between each technical characteristic new
Embodiment.
As shown in Figure 1, 2, the photovoltaic module of the utility model include the coated glass 1 set gradually downwards from light,
Transparent hot melt layer 2, battery lamella 3, white hot melt adhesive filler strip 4, black hot melt adhesive layer 5 and black backboard 6.
It is noted that battery lamella 3 includes multiple multiple cell pieces 31 being arranged, each cell piece 31 is electrically connected
The welding connect and the convergent belt for being electrically connected welding head and the tail both ends.Each cell piece 31 with welding after being connected, adjacent electricity
Gap is formed between pond piece 31.
Coated glass 1 is connect by transparent hot melt layer 2 with battery lamella 3.
Battery lamella 3 is connect by black hot melt adhesive layer 5 with black backboard 6.Under equal conditions, black object heat dissipation is than non-
Black object rapid heat dissipation, therefore select black hot melt adhesive layer 5 and black backboard 6 that can improve radiating efficiency, effectively reduce battery
The operating temperature of lamella 3.
White hot melt adhesive filler strip 4 is arranged in the gap of battery lamella 3, to prevent light from being penetrated from the gap of battery lamella 3
Onto the hot melt adhesive layer of black.Due to white hot melt adhesive can preferably reflection light, avoid light by black hot melt adhesive
Layer 5 absorbs, and advantageously reduces the operating temperature of photovoltaic module, in addition, the light reflected by white hot melt adhesive filler strip 4 can secondary counter
It penetrates and is absorbed by cell piece, also improve the power of photovoltaic module to a certain extent.
Preferably, photovoltaic module includes multiple white hot melt adhesive filler strips 4, and each white hot melt adhesive filler strip 4 is set crisscrossly
It sets.The width of each white hot melt adhesive filler strip 4 slightly larger than gap between each cell piece 31 width, to keep each cell piece 31 it
Between gap be completed covering, while white hot melt adhesive filler strip 4 being avoided to stop that heat is diffused into black hot melt adhesive from cell piece 31
Layer 5.
Preferably, photovoltaic module further includes the terminal box (not shown) being arranged on backboard 6 and is arranged in photovoltaic group
The aluminium frame 7 of part surrounding.
The photovoltaic module of the utility model can be prepared by the following method：
A, multiple cell pieces 31 are welded, coated glass 1 is placed on lamination rack；
B, transparent hot melt is laid in coated glass 1, forms transparent hot melt layer 2, it is each being welded with welding
Cell piece 31 is laid on transparent hot melt layer 2；
C, the welding at head and the tail both ends is connected using convergent belt, each cell piece 31 is made to be formed into a loop；
D, lay white hot melt adhesive filler strip 4 in the gap location of cell piece 31, then each cell piece 31 and the back side lay
Black hot melt adhesive forms black hot melt adhesive layer 5, then covers black backboard, convergent belt is pierced by from the trepanning of backboard；
E, the semi-finished product being laminated are put into be formed in laminating machine and are laminated, complete encapsulation；
F, after the completion of lamination, busbar and terminal box is connected, terminal box is fixed on backboard with silica gel；
G, with silica gel in component surrounding device aluminium frame 7.
