Description
Technical field
The present invention relates to a kind of solar cell, particularly a kind of ultra-white float glass of plated with anti-reflective coating and used for packaging solar battery assembly is the cover-plate glass of encapsulation usefulness in the crystal silicon solar battery component, is suitable for the manufacturing of crystal silicon solar battery component.
Background technology
Solar utilization technique is a popular direction of energy science emphasis research and development in this century, and the photovoltaic industry is just increasing with bigger speed, but the practical problems that present photovoltaic generation is difficult to promote the use of is that price is too high.Therefore, reduce the cost of solar electrical energy generation, the wherein crucial cost that just reduces solar module promptly needs research how reasonably to select material therefor, improves generating efficiency.Utilize sun power to generate electricity now in the world, the element that carries out opto-electronic conversion is a solar cell, and solar cell making process technology comparative maturity, the photovoltaic energy conversion efficiency ratio is higher, generally adopt at present and scale operation mainly be crystal silicon solar energy battery.Crystal silicon solar cell sheet will be assembled into assembly, could set up into large-scale solar power plant.Large-sized solar module encapsulation must be used cover-plate glass.The cover-plate glass that generally uses is that one side is pressed with than the deep-treaded energy ultrawhite figured glass now, in order further to increase the transmittance of sunlight, generally is coated with the light antireflection coatings on the no decorative pattern surface of energy ultrawhite figured glass.But there is following defective in the cover-plate glass of making of energy ultrawhite figured glass at present: complex manufacturing technology, and the cost height, cost performance is low.The manufacturing of energy ultrawhite figured glass is after sheet glass control moulding, but glass rolls glass surface with the steel rider that has special decorative pattern when still unhardened, forms the glass that is pressed with decorative pattern with definite shape, complex manufacturing technology, cost height.The original idea that makes glass surface form decorative pattern is to want to utilize the multiple reflection of sunlight in decorative pattern to increase the incident total amount of light, and this sets up in theory fully.But, now in the production of solar module, on the sheet glass that face of embossing not towards the sun, but towards cell panel, and and the EVA film bond together.Heat when battery panel components passes through the lamination stove, EVA melts, and both merge, the existence that this moment, basic naked eyes can not differentiated the glass decorative pattern, so the due extraordinary light transmission of energy ultrawhite figured glass is had a greatly reduced quality, and the light transmission reduction, cost performance descends.And another dull and stereotyped ultra-white float glass is compared with energy ultrawhite figured glass, though manufacture craft is simple, cost is low, but because dull and stereotyped ultra-white float glass transmittance is low, the power increasing amount is not high, global index is than energy ultrawhite figured glass difference, exist a lot of deficiencies, thereby dull and stereotyped ultra-white float glass is being made on the encapsulation cover plate and can't applied.Thereby will develop the used for packaging solar battery assembly cover-plate glass that a kind of manufacture craft is simple, cost is low, cost performance is high, transmittance is good is a very urgent and long-term insoluble technical barrier.
Summary of the invention
The objective of the invention is at the deficiencies in the prior art, provide that a kind of cost is low, manufacture craft is simple, cost performance is high, the ultra-white float glass of good weatherability, plated with anti-reflective coating and used for packaging solar battery assembly that light transmission power increasing amount good, that can make solar components is higher.
The technical scheme that realizes above-mentioned purpose is: a kind of ultra-white float glass of plated with anti-reflective coating and used for packaging solar battery assembly, comprise the ultra-white float glass substrate, the upper surface and the lower surface of ultra-white float glass substrate are the plane, are provided with the light antireflection coatings on the upper surface of ultra-white float glass substrate.
Further, the light antireflection coatings material of outermost one deck is a nano silicon in the light antireflection coatings.
Further, described light antireflection coatings is one deck, and the thickness of one deck light antireflection coatings is 50nm～250nm.
Further, described light antireflection coatings is two-layer, and the thickness of two-layer light antireflection coatings is 20nm～250nm.
Further, the material of the light antireflection coatings of middle one deck is any in nano titanium oxide or the nano zirconium dioxide, perhaps is the mixture of nano titanium oxide and nano zirconium dioxide.
Adopt technical scheme of the present invention, have the following advantages: cost of the present invention is low, and manufacture craft is simple, the cost performance height, and good weatherability, light transmission is good, can make the power increasing amount of solar components higher.The present invention has remedied widely used energy ultrawhite figured glass cost height in the existing solar module packaged glass, complex manufacturing technology, the deficiency that cost performance is high, also avoided existing dull and stereotyped ultra-white float glass transmittance low, the not high defective of power increasing amount, the present invention is the ultra-white float glass substrate that adopts the flat board of not embossing, the upper surface and the lower surface that are the ultra-white float glass substrate are the plane, not embossing, this ultra-white float glass substrate transmittance is 91%～91.5%, raw material is easy to get, raw materials cost is low, the present invention is that the upper surface at the ultra-white float glass substrate is provided with the light antireflection coatings, light antireflection coatings hardness height, adhere to firmly good weatherability with the ultra-white float glass substrate.With the present invention during as the packaged glass of solar module, the present invention not only can be bonding well with the EVA film, and the light antireflection coatings above the upper surface of ultra-white float glass substrate plays antireflective effect to light among the present invention, has improved transmittance.The present invention has saved a lot of operations of embossing ultra-clear glasses embossing in the prior art, and manufacture craft is simple, and cost is low, thereby the cost of solar module is also reduced thereupon greatly.When the upper surface of ultra-white float glass substrate is installed towards sunlight, it is the plane of incidence of light, after the light antireflection coatings is set on the upper surface of ultra-white float glass substrate, the light antireflection coatings is one deck, transmittance of the present invention can increase more than 1.8% on 91%～91.5% basis, the light antireflection coatings is two layers, and transmittance can increase more than 2.5% on 91%～91.5% basis.Encapsulate solar module with the present invention, can so that battery panel components in the horsepower output increasing amount after the opto-electronic conversion more than 2.5%.For powerful solar module, its power increasing amount has bigger value.Cost performance of the present invention is very high, is convenient to realize industrialization, large-scale production.
