The utility model discloses a subassembly back packaging structure's improvement has improved the heat -sinking capability of subassembly greatly, has improved the reutilization ability that the subassembly was set a camera simultaneously, and the insulating nature of subassembly also obtains guaranteeing in addition, and these characteristics can show the operating temperature who reduces the subassembly, the output and the conversion efficiency of improvement subassembly.
Description
Technical field
This utility model relates to photovoltaic module field, particularly to a kind of photovoltaic module with heat sinking back-plate.
Background technology
Solar energy is of increased attention as the renewable new forms of energy of a kind of cleanliness without any pollution; make full use of solar energy resources and can save limited fossil energy; reducing and pollute protection environment, sunlight has obtained great development and large-scale application in recent years as the photovoltaic power generation technology of green regenerative energy sources.
Now widely used photovoltaic module is essentially all by ultrawhite low ferrum safety glass, two-layer EVA(ethylene-vinyl acetate copolymer), solaode between two-layer EVA and backboard form.Along with the continuous progress of technology, the conversion efficiency of photovoltaic module is constantly raising, but still in reduced levels.In the work process of photovoltaic module, assembly is simply emitted onto the fraction luminous energy on surface and is converted into electric energy, and other major part luminous energy is converted into heat energy so that temperature during component operation is more much higher than ambient temperature.Owing to photovoltaic module has negative maximum power output temperature coefficient, thus with the rising of assembly temperature, its output, by linear decline, reduces the conversion efficiency of assembly indirectly.Therefore to improve the conversion efficiency of photovoltaic module, increase its output, it is necessary to reduce the generation of heat, derived by the heat produced in assembly in time, it is ensured that it is operated in relatively low temperature.
Summary of the invention
For problem above, the purpose of this utility model is to provide a kind of photovoltaic module with heat sinking back-plate, both ensure that the insulating properties of assembly, improves again the thermal diffusivity of assembly.
This utility model is so achieved, a kind of photovoltaic module with heat sinking back-plate, including stacking from top to bottom arrangement ultrawhite low ferrum safety glass, the first EVA layer, solar battery sheet, the second EVA layer, transparent insulating layer, the 3rd EVA layer and metal backing, layers of material is an entirety in vacuum high-temperature laminated.
Described transparent insulation layer material is TPT or PET, as being dielectrically separated between cell piece and backboard.
The thickness of described transparent insulating layer is 0.1mm ~ 0.3mm, and light transmittance is more than 90%.
Described metal backing base material is aluminum or copper product, and thickness is 0.2mm ~ 0.6mm.
Described metal backing has regularly arranged V-type or semi-circular or half elliptic groove with the surface of air contact, thus is greatly improved the heat sinking function of backboard.
Described metal backing inner surface reflectance is more than 95%.
In this utility model, ultrawhite low ferrum safety glass, solar battery sheet, between transparent insulating layer and metal backing, it is separately filled with EVA, it is ensured that the bonding between layers of material and sealing.Cell piece is isolated by transparent insulating layer with metal backing, plays the effect of insulation protection；The high optical transmittance of this layer material makes to incide the sunlight between cell piece gap and passes through and be irradiated to metal backing surface simultaneously.The surface contacted with EVA due to metal backing has high reflectance, the sunlight making the overwhelming majority incide its surface is reflected back, again being utilized by solar battery sheet, on the other hand non-reflected light is absorbed by metal backing, is converted to heat and scatters and disappears in environment.Additionally, the groove of the regular shape of the surface configuration of metal backing and air contact adds contact area between the two, accelerate the speed of assembly radiating.
Feature of the present utility model is the improvement by module backside encapsulating structure, substantially increase the heat-sinking capability of assembly, improve the assembly secondary Utilization ability to light simultaneously, additionally the insulating properties of assembly is also guaranteed, this feature will can significantly reduce the operating temperature of assembly, improves output and the conversion efficiency of assembly.
Accompanying drawing explanation
Fig. 1: a kind of photovoltaic module structure schematic diagram with heat sinking back-plate.
Fig. 2: a kind of photovoltaic module close-up schematic view with heat sinking back-plate.
In figure, 1 is ultrawhite low ferrum safety glass, and 2 is the first EVA layer, and 3 is solar battery sheet, and 4 is the second EVA layer, and 5 is transparent insulating layer, and 6 is the 3rd EVA layer, and 7 is metal backing, and 8 is V-groove.
Detailed description of the invention
The utility model is described in further detail with detailed description of the invention below in conjunction with the accompanying drawings.
As shown in Figure 1, a kind of photovoltaic module with heat sinking back-plate, including stacking from top to bottom arrangement ultrawhite low ferrum safety glass the 1, first EVA layer 2, solar battery sheet the 3, second EVA layer 4, transparent insulating layer the 5, the 3rd EVA layer 6 and metal backing 7, layers of material is an entirety in vacuum high-temperature laminated, is further encapsulated into photovoltaic module.
In the present embodiment, the thickness of transparent insulating layer 5 is preferably 0.25mm, material is preferably PET, on the one hand ensure that this transparent insulating layer has the highest light penetration, the sunray overwhelming majority inciding on transparent insulating layer is made to penetrate and incide metal backing surface, on the other hand transparent insulating layer can isolate solaode lamella metal backing very well, and transparent insulating layer has sufficiently high shelf depreciation voltage simultaneously so that assembly has good pressure performance.
As shown in Figure 2, metal backing is preferably aluminum alloy materials, its surface contacted with EVA has high reflectance to light, insulating barrier can be will transmit through incide the sunray almost all of back plate surface and reflect back, eventually pass safety glass to be totally reflected on solar battery sheet, realizing solar battery sheet to utilize the secondary of sunlight, this effect enhances the intensity of illumination in solar battery sheet front indirectly, improves output and the conversion efficiency of assembly.
Additionally, the surface of metal backing and air contact is V-groove 8, effectively increases the area of metal backing and air contact, accelerate the radiating rate of metal backing.This metal backing not only increases the heat dispersion of assembly, additionally has good barrier effect to steam, adds the ability that assembly prevents water penetration, it is ensured that the stability of assembly and reliability.
