Abstract
The invention discloses a solar cell module. The solar cell module comprises a surface protective layer, a solar cell piece, an EVA and a back surface supporting material from the upper to lower in sequence. Only a one-layer structure exists between the module cell piece and air, so that the solar cell module is good in optical transmittance, and the power output of the module is improved; and the solar cell module adopts four layers of structures in total, so that the solar cell module is simple in structure, and the packaging cost of the module is lowered.
Description
Technical field
The present invention relates to technical field of solar batteries, be specially a kind of solar module.

Photovoltaic is widely used as a kind of new forms of energy, wherein based on crystal silicon battery assembly, accounts for more than 90% of the market share.The basic structure of crystal silicon component, is followed successively by glass, EVA, cell piece, EVA, backboard from sensitive surface to shady face, totally five layers.Wherein the light transmittance of glass is the key factor affecting photovoltaic module efficiency.
But solar cell is as Application comparison a kind of new forms of energy widely at present, still needs to reduce further in cost to enhance competitiveness, also need the power output improving assembly further simultaneously.
Summary of the invention
Object of the present invention is exactly defect for above-mentioned existence and provides a kind of solar module.Only one deck between this assembly cell piece and air, has good photopermeability, improves the power stage of assembly; Assembly has four-layer structure, and structure is simple, reduces the packaging cost of assembly.
A kind of solar module technical scheme of the present invention is be made up of sealer, solar battery sheet, EVA, back support material successively from top to bottom.
Sealer is overlay.
Sealer is pet layer.
Surface protection layer thickness is 0.01-10mm.
Preferably, surface protection layer thickness is 0.5mm.
Back support material is hard plastic board or aluminium sheet.
Back support material thickness is 0.1-50mm.
Preferably, back support material thickness is 20mm.
A kind of solar module beneficial effect of the present invention is: in modular construction of the present invention, and only one deck between cell piece and air, has good photopermeability, effectively improve the power stage of assembly; Invention components has four-layer structure, and structure is simple, reduces the packaging cost of assembly.
accompanying drawing illustrates:
Figure 1 shows that the basic structure schematic diagram of prior art;
Figure 2 shows that basic structure schematic diagram of the present invention.
In figure, 1. glass, 2.EVA, 3. solar battery sheet, 4. backboard, 5. sealer, 6. back support material.
