Description
Technical field
The present invention relates to field of photovoltaic power generation, more particularly to photovoltaic generation ultra-clear glasses.
Background technology
Photovoltaic generation is ultraviolet light, the visible light of generation wavelength in silicon quantum and sunlight in the crystal silicon chip in photovoltaic module
And infrared ray reacts and generates potential difference at PN interfaces, forms the purpose that electron ion realizes power generation.
Face glass of the photovoltaic glass as solar power generation component, main function are while protecting silicon chip, relatively
The absorption and reflection to light are reduced, fully ensures that the light transmittance of light ensures that photovoltaic cell possesses higher generated output.
There is the one side of ultra-white photovoltaic list suede pattern glass the suede structure of certain roughness, another side to carry embossing face,
Embossing face is pressed into different flower-shapes by different stacks.The matte of general list matte energy ultrawhite figured glass is as upper surface, pressure
It is applied as lower surface in flower face.The main flower-shape of existing ultra-white photovoltaic list suede pattern glass has hexagon, quadrangle, flat hexagonal
Shape and diamond shape, bottom calender roll palmar density are 32 mesh/English inch (quantity for referring to single flower-shape in 1 English inch length), the flower of glass
Line depth is 45~100um, contains Fe2O3≤120ppm, the light transmittance of 380~1100nm range of wavelength light in glass ingredient
≤ 91.60%.Putting goods on the market from single matte energy ultrawhite figured glass, oneself comes, and production technology takes fixed lower surface decorative pattern close
Degree ensures light transmittance by controlling the Fe2O3 contents in glass.
Photovoltaic generation power generation is to improve the power generation of component to using the reflection and refraction of light make full use of the wavelength of light
Power needs to reduce the iron-holder in glass if needing to improve light transmittance, in this case will improve cost of material.The prior art
The light transmittance that cannot continue raising ultra-white photovoltaic glass cannot increase cell piece and be utilized to the wavelength of light, cannot then increase group
The generated output of part is unfavorable for the sustainable development of industry.
103258887 B of Chinese patent CN disclose a kind of energy ultrawhite figured glass, packet glass matrix, and the one of glass matrix
Face is equipped with matte, another side is equipped with embossing face, and the embossing face includes hexagon, quadrangle, flat hexagon and diamond shape etc.,
It is characterized in that：It is 36~100 mesh/English inch in the palmar density of the short-axis direction of embossing face upper edge flower-shape, the depth of decorative pattern is 4~
40um.The distance between upper and lower surface of the glass matrix is 1.5~6mm.Fe2O3 in the glass constituent
Content is less than or equal to 120ppm.The present invention increases and makes on this basis the depth shallower of decorative pattern because being embossed the palmar density in face,
So that light increases in the reflection of the generation in embossing face and the number of refraction, and then increase the light transmittance of glass.The present invention provides
High transparency list matte energy ultrawhite figured glass can reach 92% in the light transmittance of 380~1100nm range of wavelength light.
Its technical solution is to increase and make on this basis the depth shallower of decorative pattern by being embossed the palmar density in face so that
Light increases in the reflection of the generation in embossing face and the number of refraction, and then increases the light transmittance of glass, but with processing technology
Progress, stack roughness can reach minute surface rank, and minute surface list suede glass comes into being, but existing minute surface rolls
Roller is susceptible to slight deformation bending in the case of a high temperature, and causing two-way mirror surface layer orange peel, roll marks etc. occur influences the nature of glass
The defect of amount generates, and is further improved.
Invention content
In view of the deficiencies of the prior art, the present invention provides a kind of sunlights, and that a matte only occurs when penetrating glass is anti-
It penetrates, and reflective surface area is smaller, light transmittance is higher, about 92.0%~92.8% ultra-white photovoltaic minute surface list suede glass and its preparation side
Method.
Purpose to realize the present invention provides following technical scheme：A kind of ultra-white photovoltaic minute surface list suede glass, including base
Body, matrix include upper and lower surface, and lower surface is matte, it is characterised in that upper surface is minute surface.
Preferably, the thickness between upper and lower surface is 1.3~2.0mm.
Preferably, following table surface roughness is 0.2~1.0um, upper table surface roughness is 0.01um~0.1um.
Preferably, light transmittance >=92.0% of the matrix in 380~1100 λ m range of wavelength light.
Preferably, minute surface or matte painting are coated with single-layer or multi-layer AR film layers.
Purpose to realize the present invention provides a kind of preparation method of ultra-white photovoltaic minute surface list suede glass, it is characterised in that
Calendering formation is carried out using stack, upper roller is plain roller, and lower roll is plane matte roller, and plain roller is with matte roller to roll
Subject to roller center line, roller diameter size is 220mm~280mm.
Preferably, plain roller protrusion 15~50 since the spindle nose 400mm~520mm of stack both sides, distance calendering
Restore plane at roller center point 100mm~300mm, raised points are seamlessly transitted with requirement at crowning, and decorative pattern roughness Ra≤
0.3um.This designs the contradiction theory for solving high-temperature molding and rapid cooling.The temperature of glass liquid that the thinner glass of production needs
It is higher, need the equilibrium that glass-board surface does not occur flexural deformation and thickness then to need rapid cooling.This design convexity effect be
Solve the problems, such as that common stack cannot solve two above simultaneously, the board surface quality and thickness when to ensure that glass is molded and thickness
Spend equalization request.
Advantageous effect of the present invention：The present invention compares ultra-white photovoltaic list suede pattern glass high transparency ultrawhite provided by the invention
Photovoltaic minute surface list suede glass can reach 92%~92.8% in the light transmittance of 380~1100nm range of wavelength light, as market is sent out
Exhibition, double glass gradually replace single glass.Back-panel glass as generating electricity on two sides is in use, back-panel glass wants hole to meet double glass groups
Part perforates line demand.Energy ultrawhite figured glass can only use mechanical drilling method, yield rate to can only achieve 93% or so, perforating knife
Head easily loss, use cost are high.Product of the present invention can use more fast, and the higher laser machine of yield rate is punched, at
Product rate is up to 99% or so.Cost is substantially reduced, the sustainable development of enterprise is conducive to.
Transmission can be improved again in the minute surface or matte coating single-layer or multi-layer AR film layers of ultra-white photovoltaic minute surface list suede glass
