Abstract
A solar panel module laminated part with an aluminum-coated back film is characterized in that an aluminum-coated film layer is arranged on the upper surface of a triphenyltin (TPT) back film, and the solar panel module laminated part consists of light transmitting glass, ethylene vinyl acetate (EVA), battery plates, another EVA, the aluminum-coated film layer and the TPT back film from top to bottom sequentially by means of laminating, high-temperature curing and cooling. Since the aluminum-coated film layer is arranged on the upper surface of the TPT back film, when incident light irradiates the array clearance of the battery plates through the light transmitting glass and the EVA, light ray penetrates through the EVA below the contact plates to irradiate to the aluminum-coated film layer arranged on the upper surface of the TPT back film and full reflection is realized, and part of the light after reflection is reflected to the surfaces of the contact plates via the light transmitting glass sheet again, so that irradiation of the light on the surfaces of the contact plates is increased and efficiency of the contact plates is strengthened.
Description
Technical field:
The utility model relates to solar module, relates in particular to a kind of laminate of solar module.
Background technology:
So-called photovoltaic is the process that solar energy is converted into electric energy.Solar cell seldom monolithic uses separately, and the battery sheet that normally will have a similar characteristic is connected in series and is packaged into assembly, forms basic group of body unit of solar battery array.Solar module is made up of transparent glass, EVA, solar battery sheet, EVA and TPT usually, this different materials sorts stacked successively from the top down, form the laminate of solar components then through lamination, hot setting and cooling, the aluminium frame is installed at last again to improve its firm degree and to make it be easy to install around it, at last lead is drawn, promptly finished the making of solar components.Wherein, transparent glass and EVA are exactly the surperficial light transmissive material of solar module.
In the solar module course of work, only solar battery sheet produces the principal element of electric current, yet transparent glass and EVA have reduced the transmitance of light to some extent, how to improve the power of assembly on existing basis, the target that has just become the solar module manufacturer to chase." depth zero optically focused effect " is meant the output that increases assembly in the solar module because of the sparse arrangement of battery sheet, notacoria emission luminous energy on a small quantity, as shown in Figure 1, but sparse arrangement battery sheet must increase the area of solar components, also just increased production cost, can only improve by the reflection incident light.
The utility model content:
In order further to improve the photoelectric conversion efficiency of solar module, the utility model provides a kind of lamination of solar battery components spare with the notacoria of aluminizing.Can improve the reflectivity of light on notacoria, thereby improve the photoelectric conversion efficiency of solar components.
The technical scheme that the utility model adopted is:
Described lamination of solar battery components spare with the notacoria of aluminizing, it is made up of transparent glass, EVA, solar battery sheet, EVA and TPT notacoria, upper surface at the TPT notacoria is provided with aluminium plating membrane, stacking order from top to bottom is transparent glass, EVA, solar battery sheet, EVA, aluminium plating membrane and TPT notacoria, forms the laminate of solar components between them through lamination, hot setting and cooling.
Because the upper surface at the TPT notacoria is provided with aluminium plating membrane, when incident light is incident upon in the aligned gaps that transparent glass, EVA shine solar battery sheet, light can pass on the aluminium plating membrane that upper surface that EVA below the solar battery sheet shines the TPT notacoria is provided with, total reflection takes place then, light part after the reflection reflexes on the surface of solar battery sheet once more via transparent glass, thereby increased the irradiation that is radiated at battery sheet surface, increased the efficient of battery sheet.
Description of drawings:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a depth zero optically focused effect schematic diagram of the present utility model.
Among the figure: the 1-transparent glass; 2-EVA; The 3-solar battery sheet; The 4-TPT notacoria; The 5-aluminium plating membrane; The 6-incident light.
Embodiment:
Described lamination of solar battery components spare with the notacoria of aluminizing, as shown in Figure 1, it is made up of transparent glass 1, EVA2, solar battery sheet 3, EVA2 and TPT notacoria 4, upper surface at TPT notacoria 4 is provided with aluminium plating membrane 5, stacking order from top to bottom is transparent glass 1, EVA2, solar battery sheet 3, EVA2, aluminium plating membrane 5 and TPT notacoria 4, forms lamination of solar battery components spare by lamination, hot setting and cooling between them.
When incident light 6 is radiated on the surface of solar module, a part is radiated on the solar battery sheet 3, a part is absorbed by transparent glass 1, in the photovoltaic industry, the light transmittance of transparent glass 1 is generally greater than 91%, part incident light 6 is radiated on the TPT notacoria 4, if TPT notacoria 4 is a black, the light that then is radiated on the TPT notacoria 4 is all absorbed, if and on TPT notacoria 4, plate one deck aluminium plating membrane 5, the incident light 6 that is radiated on the TPT notacoria 4 is all reflected, incident light 6 parts after the reflection are left assembly through superrefraction, a part is radiated on the solar battery sheet 3 after reflecting through transparent glass 1, and this has just increased the irradiation that is radiated on the solar battery sheet 3, has increased the output of solar components.
