Description
Technical field
The utility model relates to photovoltaic field, particularly a kind of mono-crystalline silicon solar half flexible unit.
Background technology
Solar panel is a kind of by absorbing sunlight, solar radiation is directly or indirectly converted to the device of electric energy by photoelectric effect or Photochemical effects, crystal silicon solar energy battery plate conversion ratio higher (conversion ratio 15%-24%), but crystalline silicon battery plate is very fragile, stressedly very easily to damage, current popularization and application be adopt tempering add photovoltaic back lamination technique encapsulation make, because glass is hard, the solar components of this type is suitable for ground and installs, the isoplanar installation in roof, can be very difficult in the installation of curved surface, and stickiness is bad, as being arranged on yacht surface etc., the amorphous silicon battery encapsulation that current universal flexible unit adopts, advantage is flexible, and shortcoming is transformation efficiency low (conversion ratio 8%-12%), and the electric energy power laying equal area acquisition is much lower.
Utility model content
The purpose of this utility model is to provide one to bend, and transformation efficiency high mono-crystalline silicon solar half flexible unit.
For achieving the above object, the utility model provides a kind of mono-crystalline silicon solar half flexible unit, comprise white TPT layer, the first EVA adhesive film layer be located on white TPT layer, the cell piece group string layer be located on the first EVA adhesive film layer, the transparent TPT layer being located at the second EVA adhesive film layer on cell piece group string layer and being located on the second EVA adhesive film layer.
Preferably, described cell piece group string layer is connected in series by Monocrystalline silicon cell piece that is complete or cutting to form.
The beneficial effects of the utility model: in mono-crystalline silicon solar half flexible unit of the present utility model, transparent TPT is soft light material, white TPT is flexible material, EVA adhesive film is clear flexible material, when after laminating packaging, the front of described half flexible solar assembly is that transparent TPT can accept sunlight, the transformation efficiency of assembly can reach the standard (15%-24%) of crystal silicon solar energy battery, because transparent TPT and white TPT is flexible material, the solar components of encapsulation can bend, and reaches the object meeting high transformation efficiency and be convenient to again install at curved surface.
In order to further understand feature of the present utility model and technology contents, refer to following about detailed description of the present utility model and accompanying drawing, but accompanying drawing only provide reference and explanation use, is not used for being limited the utility model.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, by describing in detail embodiment of the present utility model, will make the technical solution of the utility model and other beneficial effect apparent.
In accompanying drawing,
Fig. 1 is the perspective exploded view of mono-crystalline silicon solar half flexible unit of the present utility model.
Embodiment
For further setting forth the technological means and effect thereof that the utility model takes, be described in detail below in conjunction with preferred embodiment of the present utility model and accompanying drawing thereof.
Refer to Fig. 1, the utility model provides a kind of mono-crystalline silicon solar half flexible unit, comprise white TPT (polyvinyl fluoride composite membrane) layer 10, EVA (vinyl-vinyl acetate copolymer) adhesive film 20 be located on white TPT layer 10, the cell piece group string layer 30 be located on the first EVA adhesive film layer 20, the transparent TPT layer 50 being located at the second EVA adhesive film layer 40 on cell piece group string layer 30 and being located on the second EVA adhesive film layer 40.
Described white TPT layer 10 is flexible materials; described white TPT layer 10 is as base plate; first and second EVA adhesive film layer 20,40 described has the characteristic of crosslinked bonding, pliable and tough, printing opacity; can be good at wrapping up protection cell piece group string layer 30 wherein; described cell piece group string layer 30 is connected in series by Monocrystalline silicon cell piece 32 that is complete or cutting to form, and transformation efficiency can reach the standard (15%-24%) of crystal silicon solar energy battery.
Product is become through laminating packaging after the layers of material of described mono-crystalline silicon solar half flexible unit stacks, during use by mono-crystalline silicon solar half flexible unit transparent area towards sunlight, be arranged on and need object surface is installed, on the semiconductor p-n junctions of solar irradiation in cell piece group string layer 30, form new hole-electron pair, under the effect of p-n junction electric field, hole flows to p district by n district, electronics flows to n district by p district, just forms electric current after connecting circuit.
In sum, in mono-crystalline silicon solar half flexible unit of the present utility model, transparent TPT is soft light material, white TPT is flexible material, EVA adhesive film is clear flexible material, when after laminating packaging, the front of described half flexible solar assembly is that transparent TPT can accept sunlight, the transformation efficiency of assembly can reach the standard (15%-24%) of crystal silicon solar energy battery, because transparent TPT and white TPT is flexible material, the solar components of encapsulation can bend, and reaches the object meeting high transformation efficiency and be convenient to again install at curved surface.
The above; for the person of ordinary skill of the art; can make other various corresponding change and distortion according to the technical solution of the utility model and technical conceive, and all these change and be out of shape the protection range that all should belong to the utility model claim.
