Description
Technical field
This utility model belongs to solar module technical field, is specifically related to a kind of high heat-conducting type backboard used for solar batteries.
Background technology
Solaode is also referred to as solar-energy photo-voltaic cell, its overall structure is known to industry, the solar energy photovoltaic glass that including: framework (generally using aluminum frame), is installed in framework, is positioned at cell piece (also referred to as silicon chip or silicon plate), hot melt adhesive layer (EVA layer), rosette and the backboard (backboard is also referred to as insulating back panel) below solar energy photovoltaic glass.
Scarcity increasingly in view of non-renewable natural resources such as oil, coal, natural gas and ocean ice; again in view of the mankind are to the economy consciousness of natural resources and being obviously enhanced of protective awareness; increasingly paying attention to utilization that is inexhaustible and that have the feature of environmental protection and cheapness resource such as wind energy and solar energy, solar energy status in the mankind's sustainable use energy strategy shows day by day.
Solaode is one of core component in solar photovoltaic generation system; it is to be laminated on by the one group of crystal silicon cell arranged in advance to constitute between ultrathin transparent and the glass of high intensity and sealing bottom; seal bottom and be backboard; owing to backboard plays the weather resistant protection of sealing to crystal silicon cell, therefore the quality of its quality is directly connected to the service life of solaode.More particularly, usually require that >=30 years service life, backboard the most used for solar batteries only possess stand out from one's fellows weatherability, resistance to ag(e)ing, insulating properties, contamination resistance is strong, water vapor transmittance (sealing) is low and shelf depreciation energy ＞ 1000V is with first-class feature, could adapt with the service life of solaode.
Prior art, in disclosed patent documentation, particularly it is no lack of the technical information being seen in about backboard used for solar batteries, such as Chinese patent CN101582458A, CN101582459A, CN201387885Y, CN201387887Y, CN101615636A, CN101431108A, CN101992571, CN101992572A, CN101979247A and CN101964371A, etc..And for example United States Patent (USP) US3133854, US513989 and US6632518, etc..These patents being not limited to enumerate are both for the weatherability of backboard, resistance to ag(e)ing, insulating properties, yellowing resistance and water vapor barrier property and propose.
As is known in the industry, (custom claims photovoltaic cell to solaode, as follows) work time can be by part ultraviolet light in daylight and substantial amounts of infra-red radiation, wherein, one length ultraviolet light also can only produce a hole-electron pair, unnecessary energy is converted into heat energy and discharges, the delivery efficiency of solaode is not had any front to help by infra-red radiation, heat energy can only be changed into, also can produce distinctive coupled thermal effects at optical-electronic transformation process simultaneously, if can not effectively dispel the heat, the temperature causing battery component is raised.According to the characteristic of semiconductor of crystalline silicon, temperature often raises 1 DEG C, and its optical-electronic conversion efficiency will fall about 0.4%.In order to avoid shining upon the temperature affecting battery module, and then affect the generating efficiency of battery module, thus the most harsh to the heat dispersion of backboard used for solar batteries.
The material of the basic unit in the structural system of the backboard used for solar batteries in prior art is usually polyethylene terephthalate (PET), owing to the heat conductivity of PET itself is relatively low, thus constrains the raising of backboard heat conductivity to a great extent.
As shown in the above description, the thermal diffusivity improving backboard both can reduce the internal temperature of solar module and contribute to protecting solar module, can improve again the optical-electronic conversion efficiency of solaode.
Equally visible all technical information being intended to improve the radiating effect of backboard used for solar batteries in disclosed Chinese patent literature, typically recommend there be " a kind of solar cell backboard and preparation method thereof and a kind of solaode " such as CN102544380B, it is with a metallic plate as carrier, single or double at metallic plate coats organic insulator, organic insulator contains titanium dioxide, polyimides and heat filling, and titanium dioxide is coupling agent modified titanium dioxide.The heat conductivity that can make backboard reaches 1.2w/m k.But there is the shortcoming that water vapor transmittance is big and polyimides is the most aging, color inhibition and ageing-resistant performance are difficult to meet the expection of industry.And for example CN104103705A is provided with " heat radiating type solar energy backboard ", and it is seven-layer structure, and wherein three layers is conducting adhesive layer, and two-layer is fluorine film, and one layer is PET, and another layer is metal basal board.Although tack coat has been made to improve by this patent application scheme, i.e. have employed conducting adhesive layer and have employed metallic plate, but limited by PET low thermal conductivity, being not enough to reach the desired radiating effect of industry equally, back board structure is complicated simultaneously and there is the anxiety of tack coat inefficacy the most under arms in the time limit." high heat radiation solar cell backboard " that CN103681915A introduces equally exists and the shortcoming of aforementioned CN104103705A.
In view of above-mentioned prior art, it is necessary to improved, to this end, the applicant has made useful design, technical scheme described below produces under this background.
Summary of the invention
The purpose of this utility model is that providing a kind of contributes to significantly improving heat dispersion and use and effectively reduce the temperature within solar module and improve the optical-electronic conversion efficiency of solaode and be conducive to simplification structure and use the high heat-conducting type backboard used for solar batteries of convenient making.
The purpose of this utility model is such to reach, a kind of high heat-conducting type backboard used for solar batteries, including basic unit, weathering layer and internal layer, weathering layer is combined with basic unit towards the side of basic unit by the first tack coat, weathering layer is combined with internal layer towards the side of internal layer by the second tack coat, it is characterised by: described basic unit is heat-conducting type mylar, described weathering layer is heat-conducting type fluorinated copolymer layer, described internal layer is heat-conducting type fluorinated copolymer layer or heat-conducting type polyolefin copolymer nitride layer, the first described tack coat and the second tack coat are heat-conducting type polyurethane adhesive layer.
This utility model provide technical scheme have the technical effect that owing to being compounded with weathering layer and internal layer in basic unit successively, thus have that the weatherability of excellence and ageing-resistant performance, insulating properties, contamination resistance, water vapor transmittance be little, shelf depreciation ability is more than more than 1000V, it is ensured that service life reaches more than 25 years；Owing to basic unit is that heat-conducting type mylar, weathering layer are heat-conducting type fluorinated copolymer layer and internal layer is heat-conducting type fluorinated copolymer layer or heat-conducting type polyolefin copolymer nitride layer, thus there is the heat dispersion stood out from one's fellows, the temperature within solar module can be significantly reduced, improve the photoelectric transformation efficiency of cell piece.
