Abstract
The invention relates to a self-temperature-reducing solar energy backboard, which comprises a PET substrate. One side of the PET substrate is connected with a weather-resistant layer through a bonding layer; a reflecting layer is arranged on the upper surface of the weather-resistant layer; the other side of the PET substrate is connected with a weather-resistant bonding layer through a bonding layer; and a radiation layer is connected to the lower surface of the weather-resistant bonding layer. The reflecting layer is formed by any one of titanium oxide, zinc oxide or tin-antimony oxide; and the radiation layer is formed by any one of metal oxide, metal carbide or metal alkalide. The self-temperature-reducing solar energy backboard is simple in structure and convenient to use, and can reduce the temperature of the whole backboard effectively, thereby preventing the problem of power reduction due to over-high temperature, improving overall power, reducing material aging rate due to overlarge temperature difference and improving service life and photoelectric conversion efficiency of the solar energy backboard.
Description
Technical field
The present invention relates to solar components field, more particularly, to one kind is from cooling type solar energy backboard.
Background technology
Solar energy, as a kind of environmental protection, the inexhaustible energy, replaces the optimal choosing of traditional thermal power generation beyond doubt
Select, because solar cell needs to be chronically exposed to outdoor practicality, so the cell piece in photovoltaic module needs to be protected by, come
Prevent the impact of environmental factor and the vertical views such as steam in air, oxygen, ultraviolet.Solar energy backboard is whole solar cell
One of accessory, the effect acting primarily as mechanical support and protecting cell piece permeate from environmental factor, the solar energy of routine at present
The conversion ratio of battery back-sheet its efficiency in high temperature environments substantially reduces, and greatly reduces the service life of backboard.
Content of the invention
The applicant is directed to above-mentioned existing issue, has carried out Improvement, provides one kind from cooling type solar energy backboard, its
Effectively increase solar energy backboard power and service life.
The technical solution adopted in the present invention is as follows:
A kind of from cooling type solar energy backboard, including pet base material, the side of described pet base material is connected resistance to by tack coat
Wait layer, in the upper surface setting reflecting layer of described weathering layer, the other end in described pet base material connects weather-proof gluing by tack coat
Knot layer, the lower surface in described weather-proof tack coat is also connected with radiating layer；Described reflecting layer is aoxidized by titanium oxide, zinc oxide or tin antimony
Any one composition in thing；Described radiating layer is by any one in metal oxide, metal carbides, metal alkali compound.
Its further technical scheme is:
The thickness in described reflecting layer is 100 μm～200 μm, and the thickness of described radiating layer is 150～250 μm.
Beneficial effects of the present invention are as follows:
Present configuration is simple, easy to use, it can effectively reduce the overall temperature of backboard, it is to avoid due to temperature mistake
The problem of the power drop that height leads to, improves overall power, slow down the speed of the material aging causing because of excessive temperature differentials
Rate, improves service life and the photoelectric transformation efficiency of solar energy backboard.
Brief description
Fig. 1 is the structural representation of the present invention.
Wherein: 1, weathering layer；2nd, tack coat；3rd, pet base material；4th, weather-proof tack coat；5th, reflecting layer；6th, radiating layer.
Specific embodiment
The specific embodiment of the present invention is described below.
One kind of the present invention includes pet base material 3 from cooling type solar energy backboard, and bonding is passed through in the side of pet base material 3
Layer 2 connection weathering layer 1, in the upper surface setting reflecting layer 5 of weathering layer, the other end in pet base material 3 is connected by tack coat 2
Weather-proof tack coat 4, the lower surface in weather-proof tack coat 4 is also connected with radiating layer 6；Reflecting layer 5 is by titanium oxide, zinc oxide or tin antimony oxygen
The composition of any the present embodiment in compound；Radiating layer is by any basis in metal oxide, metal carbides, metal alkali compound
Embodiment.The thickness in reflecting layer 5 is 100 μm～200 μm, and the thickness of radiating layer 6 is 150～250 μm.
Present configuration is simple, easy to use, it can effectively reduce the overall temperature of backboard, it is to avoid due to temperature mistake
The problem of the power drop that height leads to, improves overall power, slow down the speed of the material aging causing because of excessive temperature differentials
Rate, improves service life and the photoelectric transformation efficiency of solar energy backboard.Reflecting layer in the present invention can make to expose to backboard
Light reflection, it is to avoid solar energy backboard raises due to absorbing the own temperature that light causes, and increased solar energy backboard simultaneously
Absorptivity to light.
Above description is explanation of the invention, is not the restriction to invention, limited range of the present invention is referring to right
Require, in the case of the basic structure without prejudice to the present invention, the present invention can make any type of modification.
