Description
Technical field
The utility model is related to generating electricity on two sides solar double-glass assemblies back-panel glass, more particularly to one kind having both antireflective and high reflection
Generating electricity on two sides solar double-glass assemblies back-panel glass.
Background technology
Commonly photovoltaic double-glass assembly refers to just：By two pieces of tempered glass, EVA adhesive film and silicon chip of solar cell, by layer
The lamination of press high temperature forms composite layer, and being pooled to lead end by conducting wire series and parallel between cell piece is formed by photovoltaic cell group
Part.It includes the first layer toughened glass layer from top to bottom set gradually, second layer PVB or PO or EVA or ionomer material
The bed of material, third layer monocrystalline or polycrystalline battery layer, the 4th layer of PVB or PO or EVA or ionomer material layer and layer 5 steel
Change glass or high saturating backsheet layer, reflecting layer is realized by white EVA.
Nearest generating electricity on two sides photovoltaic module starts to grow up, and such as double-side assembly Duomax twin, this is a innovative
Product is combined on the basis of Trina Solar solar double-glass assemblies with efficient double-side cell technology, and uses transparent sealing material
Material, between double-sided solar high-efficiency battery is packaged in layer glass, enables component to be absorbed except optical energy power in front, component
The also absorbable ground launch light in the back side and atmospheric scattering light carry out additional power.Therefore, which is suitable for ground and neighboring buildings
Reflected light and the stronger area of scattering light make the generated energy of the tow sides of component reach such as high latitude area and snowy district
It maximizes, while being also applied for the special applications such as Photovoltaic Building Integration.Have benefited from its unique design, Duomax twin are bis-
The generated energy highest of face solar double-glass assemblies can be higher by common single sided assemblies 25% or so so that and system power benefit is significantly increased, from
And bring more low electric cost.
The output power of photovoltaic module is related with the utilization rate of the light intensity and light that are incident to cell piece surface, improves light
Utilize the output power that can effectively improve component.Photovoltaic module is typically to be connected in series or in parallel by multiple cell pieces, cell piece
Between gap sunlight can be reflected back on glass, the refraction of the glass of process is reflected on cell piece the output for increasing component
Power.In common double wave component photovoltaic module, the gap between cell piece can be increased too by white Eva backboards to fill
It is positive can reflecting rate improve the output power of photovoltaic module, but for generating electricity on two sides photovoltaic module, white Eva backboards are due to hiding
Gai Xing cannot just be used, it is necessary to the gap between cell piece is filled in using coating.The two-sided hair designed by using us
The luminous energy of electric solar double-glass assemblies back-panel glass, generating electricity on two sides solar double-glass assemblies back surface incident is effectively promoted, while between cell piece
Gap is reflectance coating, is promoted in light reflection to cell piece, whole to promote generating electricity on two sides solar double-glass assemblies power.
