Abstract
The utility model discloses a kind of film assembly being laminated for photovoltaic solar cell, including the upper strata PVB film positioned at cell piece top and the bottom PVB film positioned at cell piece bottom, it is provided with the bottom PVB film between battery settling groove, the mounting groove and is provided with busbar installation groove.The utility model reduces the deflection of film in lamination process due to groove film, and the incidence of cell piece breakage rate and filling badness is greatly reduced, and can increase substantially the yield rate of solar double-glass assemblies.Being capable of effectively self-contained battery piece and busbar using such a groove film, reduction cell piece shifts pressure-bearing and breakage ftractures, prevents the generation of the quality problems such as busbar sealing-off, component package yield rate is improved, the thickness of film can also be further thinned, lightweight packages are reduced.
Description
Technical field
The utility model belongs to PVB films production and processing technical field, and in particular to one kind is used for photovoltaic solar cell layer
The film assembly of pressure.
Background technology
Photovoltaic solar cell piece can not be directly exposed under the natural conditions such as sunlight, rainwater, it is therefore necessary to which it is entered
Row sealing protection.The encapsulating material used at present is ethene-vinyl acetate co-polymer (EVA) of single layer structure, long-term
Under hot and humid environment, EVA easily hydrolyzes destruction, causes the caking property of EVA and glass interface to be decreased obviously, causes solar energy
There is potential safety hazard in battery component.Another is exactly polyvinyl butyral resin（PVB）Be that a kind of compliance is good, transparency is high,
Bonding force is strong, weatherability is strong, good film-forming property, the material of excellent impact resistance, to the materials such as glass, metal, timber all have compared with
Good adhesive property, PVB is used for solar cell package material, when its uvioresistant, penetration and glass bonding force and storage
Between will be better than ethylene-vinyl acetate copolymer（EVA）, but in solar double-glass assemblies and film battery assembly lamination process, by
Have certain thickness by oneself in itself in cell piece, often occur the problem of diaphragm filling is insufficient, excessive compression damages cell piece.
The content of the invention
In view of this, it is necessary to a kind of film assembly being laminated for photovoltaic solar cell is provided, to overcome existing skill
Often occurs the technical problem that diaphragm filling is insufficient, excessive compression damages cell piece in art in film lamination process.
The utility model provides a kind of film assembly being laminated for photovoltaic solar cell, including positioned at cell piece bottom
Bottom PVB film and the upper strata PVB film positioned at cell piece top, be provided with battery settling groove in the bottom PVB film,
Busbar is provided between the mounting groove groove is installed.
Further, the cell piece mounting groove is uniformly distributed in bottom PVB film, and its depth is 0.1-0.35mm,
It is preferred that 0.15-0.25mm；The cell piece installs groove sidewall to inclination on the outside of battery, and tilt angle alpha is 5-30 °, preferably 8-
15°。
It is square or circular arc that the busbar, which installs bottom portion of groove, and its depth is 0.1-0.35mm, preferably 0.1-
0.15mm。
Upper strata PVB film described in the utility model is flat film, and surface roughness is Rz50-100 μm.
The utility model is after film raw material is extruded in flakes via mould, then via with punch-pin shape in process
The disk roller of formula is squeezed out with groove shapes diaphragm.The deflection of film in lamination process is reduced due to groove film, battery
The incidence of piece breakage rate and filling badness will be all greatly reduced, and can increase substantially the yield rate of solar double-glass assemblies.Using this
Kind of groove film can effectively self-contained battery piece and busbar, reduce cell piece displacement pressure-bearing and damaged ftracture, prevent busbar
The generation of the quality problems such as sealing-off, improves component package yield rate.The thickness of film can also be further thinned, component weight is reduced
Amount.

Embodiment
Embodiment of the present utility model is further described below in conjunction with the accompanying drawings：
Referring to Fig. 1-4, after the utility model is extruded in flakes to PVB film raw materials via mould first, then via with convex
The disk roller of modular form is squeezed out with groove shapes bottom PVB film 2.Battery settling groove is provided with the bottom PVB film 2
21, the cell piece mounting groove 21 is uniformly distributed in bottom PVB film 2, and its depth is 0.1-0.35mm, preferably 0.15-
0.25mm.Its length and width is corresponding with photovoltaic cell chip size, so that steady self-contained battery piece.Further, the electricity
The side wall of pond piece mounting groove 21 is to inclination on the outside of battery, and tilt angle alpha is 5-30 °, preferably 8-15 °.By the way of excessive using oblique angle,
Facilitate inserting and the subsequently filling of lamination process for photovoltaic cell.
Busbar is additionally provided between the battery settling groove 21 groove 22 is installed, the busbar installs the bottom of groove 22
For square or circular arc, its depth is 0.1-0.35mm, preferably 0.1-0.15mm.The depth that busbar installs groove 22 is less than
The depth of cell piece mounting groove 21, can preferably fixing bus-bars and convenient welding.
Upper strata PVB film described in the utility model 1 is flat film, and surface roughness is Rz50-100 μm.
During solar photovoltaic battery component encapsulation process of the present utility model, this had into groove shapes bottom PVB film 2
Cut by required size and be laid in back-panel glass（Not shown in figure）On, cell piece is embedded into battery settling groove 21, and is filled
Busbar is welded, the busbar is fixed on busbar and installed in groove 22.Repave and load onto layer PVB film 1.Afterwards using conventional
Vacuum deaeration or rolling laminating continue postorder processing, you can complete photovoltaic solar cell plate encapsulation.
The film assembly of photovoltaic solar cell lamination of the present utility model, using two different form of PVB film phase
Mutually use cooperatively, upper strata PVB film is flat film, and be conducive to exhaust in processing pressing process with preferable roughness,
Bottom film uses form of grooves, because the more conventional film of the deformation of film is wanted when carrying out lamination process using such a groove film
