Description
Technical field
The utility model relates to technical field of solar batteries, particularly relates to a kind of solar module.
Background technology
The solar module cover-plate glass is called the solar energy glass cover plate again; because the solar module cover-plate glass has solar photovoltaic conversion rate height, plate crushes the characteristics that loss rate is low, intensity is high, evenness is good; fully the transmission sunlight absorbs for solar battery sheet; and protect solar battery sheet under it not by the damage of bad weathers such as extraneous wind and frost sleet or space service conditions with the intensity of self; therefore, the solar module that is widely used in monocrystalline silicon piece, polysilicon chip and the amorphous silicon chip of all kinds, all size.
At present, the comparatively general solar module cover-plate glass of Cai Yonging, its structure comprises surface with smooth flat and the surface with embossing aspect.When solar module encapsulates, will have incident one side of the surface of smooth flat towards sunlight, will have the side of the surface of embossing aspect, and seal bonding by EVA layer and solar battery sheet towards solar battery sheet.
All the time, it is believed that the encapsulation of solar module, can only be to have the side of the surface of smooth flat towards sunlight incident, to have the side of the surface of embossing aspect towards solar battery sheet, mainly be owing to the surface with embossing aspect can be bonding firmly with the EVA layer, be difficult for causing battery drain.Yet during the surperficial incident of incident ray by this smooth flat, transmitted light is less than 92 ﹪, the loss of the reflection ray of 8 ﹪ that still have an appointment.So, how to reduce the reflection ray that incides the solar module cover-plate glass more effectively, become the research emphasis that people further improve solar module cover-plate glass light transmittance.
For solving above-mentioned technology prejudice problem, Granted publication number is: the Chinese utility model patent of CN 100495734C disclosed a kind of " glass plate used for solar cell module packaging " on June 3rd, 2009, its technical scheme is: " comprising 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; wherein; the coating above the described glass substrate is that the utilization nano material forms; 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, described coating layer thickness is 130nm～145nm, two relative up and down edge lengths c values are 0.2mm in the regular hexagon of the honeycomb mouth distortion in the described embossed layers decorative pattern, and the honeycomb depth d value in the described embossed layers decorative pattern is 0.55mm～0.6mm.”
Though the technical scheme of the Chinese utility model patent of above-mentioned CN 100495734C has overcome traditional technology prejudice, adopt the technical scheme opposite with traditional thinking, when the encapsulation of solar module, with the one side of embossed layers towards sun light inlet side, with the side of smooth flat towards solar battery sheet.But in actual use, this smooth flat and EVA layer are bonding not firm, easily cause the phenomenon of battery drain; And, embossed layers adopts cellular pattern structure and the regular hexagon of honeycomb mouth for being out of shape, the mould of making this structure is comparatively complicated, and there are corner angle between each honeycomb, because solar module is arranged on abominable outdoor of environment more, the structure of this corner angle formula causes the easy dust stratification dirt in the surface of solar module cover-plate glass easily, difficult cleaning.Above-mentioned patent simultaneously is coated with and coating glass-modified and reduction tension force can be realized problem easy to clean by adopting the embossed layers at glass substrate, but the thickness of coating only is 130nm～145nm, angular structures between the honeycomb still exists, even the coating of setting up, still make the easy dust stratification dirt in surface of solar module cover-plate glass, also increased the processing step of making cover-plate glass simultaneously, increase the cost of solar module virtually, made Application of Solar Energy, popularization, universal difficulty increase thus.
Therefore, needing badly provides a kind of reflection loss can reduce sunlight incident the time, effectively converging when guaranteeing the sunlight transmission is difficult for dust stratification dirt, easy to clean again, and the manufacturing process solar module with solar module cover-plate glass simple, with low cost.
