Abstract

The utility model discloses a crystalline silicon solar cell component, which is characterized by comprising a crystalline silicon solar cell (3). A toughened glass layer (1) and a PET (polyethylene terephthalate) back plate material layer (5) are respectively disposed on the upper and lower sides of the crystalline silicon solar cell (3), a high-transmittance EVA (ethylene vinyl acetate) adhesive film layer (2) is arranged between the toughened glass layer (1) and the crystalline silicon solar cell (3), and an ultraviolet EVA adhesive film layer (4) is disposed between the PET back plate material layer (5) and the crystalline silicon solar cell (3). Photoelectric conversion efficiency of the crystalline silicon solar cell component can be improved to the utmost extent, and a PET back plate of the solar cell component can be effectively protected.

Description

A kind of crystal silicon solar battery component
Technical field
The utility model relates to a kind of crystal silicon solar battery component, belongs to the solar-photovoltaic technology field.
Background technology
At present both at home and abroad the method for packing that crystal silicon solar battery component is commonly used is: will hang down iron toughened glass, EVA glued membrane, crystal silicon solar energy battery, EVA glued membrane, TPT or PET back veneer material stacked after, heating also vacuumizes the pressurization encapsulation, produces solar module.The main effect of EVA glued membrane in solar module has: 1, protect the crystal silicon solar energy battery operate as normal long-term effectively; 2, be adhesively fixed well together with glass, solar cell, backboard etc.; 3, very high light transmittance does not influence the electricity conversion of solar cell.The domestic and international at present EVA glued membrane that uses, it is identical being wrapped in crystal silicon solar energy battery two-layer EVA glued membrane up and down, has identical performance.In addition, be the composite products of base material because the crystal silicon solar battery component back veneer material adopts PET in a large number, this back veneer material is subject to ultraviolet radiation and aging yellowing etc.
The utility model content
The purpose of this utility model is, a kind of crystal silicon solar battery component is provided, and it both can improve the electricity conversion of crystal silicon solar battery component to greatest extent, can protect the PET backboard of solar module again effectively.
The technical solution of the utility model: a kind of crystal silicon solar battery component, it is characterized in that: comprise crystal silicon solar energy battery, crystal silicon solar energy battery is respectively equipped with toughened glass layer and PET back veneer material layer up and down, be provided with high-transmission rate EVA adhesive film (EVA is the abbreviation of ethylene-vinyl acetate copolymer) between toughened glass layer and the crystal silicon solar energy battery, be provided with every ultraviolet EVA adhesive film between PET (poly terephthalic acid ethylene glycol) back veneer material layer and the crystal silicon solar energy battery.
In the aforesaid crystal silicon solar battery component, described high-transmission rate EVA adhesive film is a light transmittance greater than 90% EVA glued membrane.
In the aforesaid crystal silicon solar battery component, described is ultraviolet ray transmissivity less than 5% EVA glued membrane every ultraviolet EVA adhesive film.
Compared with prior art; the utility model is by being provided with the different EVA glued membrane of two layer functions, and the EVA glued membrane on upper strata is mainly realized high transmission function, thereby improves the efficient of solar cell; and the PET backboard is protected in being mainly used in of lower floor, therefore mainly realizes intercepting and absorbing ultraviolet function.The utility model can improve the electricity conversion 0.5~3.0% of crystal silicon solar battery component, and the PET backboard of solar module also because be protected, both can delay the xanthochromia of PET inner layer material, PET can be prolonged 5~10 years useful life again.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Being labeled as in the accompanying drawing: 1-toughened glass layer, the high transmission EVA of 2-adhesive film, 3-crystal silicon solar energy battery, 4-be every ultraviolet EVA adhesive film, 5-PET back veneer material layer.
Embodiment
Below in conjunction with drawings and Examples the utility model is further described, but not as the foundation to the utility model restriction.
Embodiment.A kind of crystal silicon solar battery component, constitute as shown in Figure 1, it is characterized in that: comprise crystal silicon solar energy battery 3, crystal silicon solar energy battery 3 is respectively equipped with toughened glass layer 1 and PET back veneer material layer 5 up and down, be provided with high-transmission rate EVA adhesive film 2 between toughened glass layer 1 and the crystal silicon solar energy battery 3, be provided with every ultraviolet EVA adhesive film 4 between PET back veneer material layer 5 and the crystal silicon solar energy battery 3.Described high-transmission rate EVA adhesive film 2 is a light transmittance greater than 90% EVA glued membrane.Described is ultraviolet ray transmissivity less than 5% EVA glued membrane every ultraviolet EVA adhesive film 4.
