Description
Technical field
The present invention relates to a kind of solar module, particularly a kind of glass plate used for solar cell module packaging.
Background technology
At present, known solar photovoltaic conversion relies on is battery sheet in the solar module, the battery sheet has good absorption effects, along with people's updating to solar module, the electricity conversion of the battery sheet in the solar module has reached higher level, therefore people set about constantly development and improve in the solar module glass plate light transmittance as cover closing material, to reach the purpose of the relative electricity conversion of further raising whole solar cell.Meanwhile, because the workplace of solar cell is arranged on abominable outdoor of environment more, causes the glass plate used for solar cell module packaging surface easily dirty, and be difficult to cleaning again after dirty.Therefore when improving used for packaging solar battery assembly photovoltaic glass plate light transmittance, also to make after the glass plate used for solar cell module packaging surface contamination easy to clean.The following several structural shapes of the general employing of present known glass plate used for solar cell module packaging: a kind of is the common ultra-clear glasses that adopts floating process to produce, this glass iron-holder is low, surface smoothing is bright and clean, and the shortcoming of this glass is that reflectivity is too high; Second kind is the common ultra-clear glasses that adopts calendering technology to produce, and this glass iron-holder is low, and the shortcoming of this glass plate is that printing opacity is not had an X-rayed; The third is present better performances, also is generally adopt a kind of, promptly one side is a smooth flat, one side is the energy ultrawhite figured glass of embossed layers, when solar module encapsulate, with the smooth flat of energy ultrawhite figured glass simultaneously outwardly, promptly towards the sun one side, with embossed layers one side inwardly, promptly towards solar battery sheet one side, the iron-holder of this energy ultrawhite figured glass is low, decorative pattern shape on the embossed layers has multiple shape, and the more common ultra-clear glasses of refractiveness will be got well.Above-mentioned three kinds of ultra-clear glasses all exist very large defective simultaneously, are exactly that self-cleaning performance is poor.Therefore, people are in order to solve the shortcoming of glass plate used for solar cell module packaging from clear poor performance, improve, coating in smooth flat one side of the third energy ultrawhite figured glass can be with coating glass-modified and reduction tension force, to overcome this defective, the coating that applies on energy ultrawhite figured glass at present has multiple, if any main component is silicon dioxide and the coating of infiltrating rare earth, disclosed Chinese patent application (notification number CN1807319A is arranged, open day on July 26th, 2006, apply for a patent title " highly effective solar energy electrooptical effect glass ") in, disclosed coating is made up of zirconia and magnesium fluoride, their percentage by weight is a zirconia 25%～38%, magnesium fluoride 62%～75%.These energy ultrawhite figured glass automatically cleaning abilities that added coating are better, but light transmission also is not very desirable.Thereby, want to improve the light transmittance of solar module packaged glass plate at present biglyyer, to have the automatically cleaning ability again be a technical barrier to glass plate always simultaneously.
Summary of the invention
The objective of the invention is at the deficiencies in the prior art, the glass plate used for solar cell module packaging that a kind of light transmission is higher, the power added value is higher, have the automatically cleaning ability is provided.
The technical scheme that realizes above-mentioned purpose is: a kind of glass plate used for solar cell module packaging, comprise glass substrate and the coating that is coated in above the glass substrate, the one side of glass substrate is provided with the embossed layers that has decorative pattern, and the coating above the glass substrate is coated in the embossed layers surface.
Further, decorative pattern on the embossed layers is shaped as cellular, the honeycomb mouth is the regular hexagon of distortion, relative up and down both sides are parallel to be equated, all the other four limits equate, be 0.8mm with the parallel catercorner length a value in relative up and down both sides in the honeycomb mouth, the vertical range b value between the relative up and down both sides is 0.9mm.
Further, described coating layer thickness is 130nm～145nm.
Further, two relative up and down edge lengths c values are 0.2mm in the regular hexagon of the distortion of the honeycomb mouth in the described embossed layers decorative pattern.
Further, the honeycomb depth d value in the described embossed layers decorative pattern is 0.55mm～0.6mm.
Adopt glass plate used for solar cell module packaging of the present invention, have the following advantages: (1) light transmittance height, spotlight effect is good.Traditional technology prejudice that the present invention overcomes, adopted the technical scheme opposite with traditional thinking, the present invention is when installing and using, with embossed layers one side of the present invention outwardly, promptly towards the sun one side, with smooth flat one side inwardly, promptly towards solar battery sheet one side, and embossed layers simultaneously adopts decorative pattern numeric dimensions of the present invention, gradient is big, can realize repeatedly slow reflection function, so the light transmittance height, spotlight effect is good; (2) the automatically cleaning ability is strong.The present invention simultaneously is coated with at the embossed layers of glass substrate can be with glass-modified and reduce the coating of tension force, and glass surface is the coating that the utilization nano material forms, the concavo-convex microstructure of hydrophobicity that it is good and surface anti-static makes above dust can't stick to, the cleaning that under normal erosions such as rainwater, keeps glass surface, reached the purpose of automated cleaning, better than artificial cleaning effect, and the cost and the danger of having saved artificial cleaning; (3) the power added value is higher.The power added value of solar components is more than 3 times of original coating technique; (4) long service life.The coating hardness of glass surface is big, and durability degree is good, can reach more than 20 years, makes glass obtain effective protection, has prolonged the useful life of glass, thereby has also reduced use cost; (5) has antibacterial and antimildew function.Because glass plate and coating material are Inorganic Non-metallic Materials, therefore has antibacterial and antimildew function; (6) perfect heat-dissipating.Because the present invention is when installing and using, the embossed layers one side outwardly, the area of dissipation on the unit glass surface is big, so perfect heat-dissipating, can avoid the heat fade of solar module.
