[0008] [0008]

为了实现上述目的,本发明采用以下技术方案:一种防眩光太阳能电池组件,包括设置在顶层的ETFE前板及设置在底层的玻璃背板,所述ETFE前板与玻璃背板之间设有太阳能电池片,各列太阳能电池片通过焊带串联构成电池串,电池串之间通过汇流条相连构成太阳能电池矩阵,所述ETFE前板与太阳能电池片、太阳能电池片与玻璃背板之间均设有热熔胶层,所述ETFE前板表面设有散射槽,所述散射槽纵横交叉呈网格结构。 To achieve the above object, the present invention employs the following technical scheme: An antiglare solar cell module comprising a front plate disposed ETFE and disposed between the bottom of the top back glass, the glass back plate and the front ETFE provided solar cells, solar cells through the columns in series battery string ribbon between the cell strings are connected by bus bars constitute a solar cell array, ETFE between the front plate and solar cells, solar cells and glass back are with a hot melt adhesive layer, the ETFE front surface of the plate with a scattering of slots, said slots crossbar scattering a grid structure. 本发明中的前板采用ETFE材料制成,ETFE材料非常轻,ETFE材料的重量大约只为同体积的超白钢化玻璃质量的百分之一,其次,ETFE材料透光率高,超白钢化玻璃的紫外截止波长一般为380nm,透光率为90~92%,而ETFE材料的透光率为95~97%,紫外截止波长一般为300nm,因此,ETFE材料相对于超白钢化玻璃有更好的透光率和更低的紫外截止波长,同样条件下可以透过更多的光能,使电池片受光更多,可提高电池的转换效率,而且,ETFE材料表面无孔光滑,灰尘、雨水及雪等污垢不会积存,更为重要的是,ETFE材料与热熔胶层间的结合强度高,不易脱开;本发明中ETFE前板的表面设有纵横交叉呈网格结构的散射槽,散射槽能使反射的光线发生漫反射,从而消除了眩光效果与光污染,同时散射槽还能使反射的部分光线发生折射再次进入电池,从而提高电池的转换率,最重要的是,散射槽能起到缓冲腔的作用,当ETFE前板瞬间受到较大的外力作用时(如遭受冰雹打击等),ETFE前板上受力处的ETFE材料会向四周挤压产生形变(发生凹陷),而散射槽可有效分散ETFE前板所受到的作用力,有效避免ETFE前板发生凹陷。 The front plate of the present invention using ETFE materials, ETFE material is very light weight ETFE material is approximately only one percent over the same volume of quality white tempered glass, and secondly, ETFE material high transmittance, super white tempered glass UV cutoff wavelength is generally 380nm, light transmission rate of 90 to 92%, while the ETFE material transmittance of 95 to 97% of UV cut-off wavelength is typically 300nm, therefore, ETFE material relative to the ultra-white glass more Good light transmittance and lower cutoff wavelength ultraviolet, under the same conditions by more energy, so that more light receiving cells, can improve the conversion efficiency of the battery, and, ETFE nonporous smooth surface, dust, rain and snow will not accumulate dirt, more importantly, high bonding strength ETFE material and the hot melt adhesive layers, is difficult to separate; the surface of the present invention, ETFE front plate is provided with a grid structure crossbar scattering slot, slot enables scattering light reflected diffusely reflected, thereby eliminating the effects of glare and light pollution, but also make scattering grooves reflected portion of the light is refracted again into the battery, thereby improving cell conversion rate, most importantly, scattering can play the role of a buffer tank chamber, when ETFE front plate moment subject to greater external force (such as blow suffered hail, etc.), ETFE force at the front panel will be around to squeeze ETFE material deforms (occurring depressions) while scattering groove can be effectively dispersed ETFE front plate by force, effectively prevent the occurrence of ETFE front plate depression.

[0009] 作为优选,所述散射槽截面呈U形。 [0009] Advantageously, the scattering cross section U-shaped groove.

[0010] 作为优选,所述散射槽的宽度为0.5~lmm,深度为0.2^0.4mm,相邻散射槽之间的间隔为2~4mm。 [0010] Advantageously, the scattering width of the groove is 0.5 ~ lmm, a depth of 0.2 ^ 0.4mm, the interval between the adjacent grooves scattering 2 ~ 4mm. 散射槽宽度、深度及相邻散射槽之间的间隔过大或过小,均会影响使用效果,也就是防眩光效果差,同时散射槽宽度、深度及相邻散射槽之间的间隔过小,也不利于散射槽的设置。 Scattering groove width, depth and spacing between adjacent grooves scattering too large or too small, will affect the results, anti-glare effect is poor, while scattering spacer groove width, and depth of the groove between adjacent small scattering It is not conducive to a scattering groove.

[0011] 作为优选,所述ETFE前板厚度为3~5mm。 [0011] Advantageously, the thickness of the front plate ETFE 3 ~ 5mm. 由于ETFE前板位于顶层,厚度太薄,结构强度不够,在受到外力的作用下易造成其下层的硅片造成破裂,同时过薄的厚度也不利于散光槽的设置,而且在层压时极易发生褶皱与位移,而ETFE前板厚度过大,则成本上升。 Since ETFE front plate on the top floor, the thickness of thin, structural strength is not enough, in the role of external forces by its underlying silicon could easily lead to cause rupture, while too thin thickness is not conducive to setting astigmatism groove, and during lamination pole prone to wrinkles and displacement, and too large thickness ETFE ago, the cost rises.

[0012] 作为优选,所述热熔胶层为EVA层。 [0012] Advantageously, the EVA layer is a layer of hot melt adhesive.

[0013] 一种防眩光太阳能电池组件的制备工艺,包括以下步骤: [0013] A process for preparing an antiglare solar cell module, comprising the steps of:

[0015] (C)将敷设好的组件放入压层机进行层压。 [0015] (C) will lay a good assembly into the laminating machine lamination. 层压时,ETFE前板受热软化,网格布则会嵌入ETFE前板,起到凸模的作用,同时网格布还具有定型的作用,防止层压时ETFE前板产生褶皱和位移,本发明中的ETFE前板厚度达3~5mm,厚度较厚,在层压过程中ETFE前板表面会产生褶皱,因此现在应用于太阳能电池组件上的都是厚度在0.3mm以下的ETFE膜,而网格布在层压时会嵌入ETFE前板表面,正好起到骨架和模板的作用,抑制ETFE前板表面产生褶皱和发生位移,有效解决了层压过程中ETFE前板表面会产生褶皱与位移的问题。 Lamination, ETFE front plates are heated to soften, ETFE mesh is embedded in the front panel, to play the role of punch, while mesh also has the role of stereotypes, prevent wrinkles and ETFE front plate displacement during lamination, this The invention ETFE thickness of the front plate 3 ~ 5mm, thicker in the front plate lamination process ETFE surface will produce wrinkles, and therefore are now applied to a thickness of the solar cell module on the ETFE film in 0.3mm or less, and When laminated mesh embedded in ETFE front panel surface, just play the role of the skeleton and templates, inhibition ETFE front panel surface wrinkles and displacement, effective solution to the front surface of the laminate ETFE process will produce wrinkles and displacement problems. [0016] (d)待层压后的组件冷却、固化后,揭下网格布,在ETFE前板表面形成纵横交叉呈网格结构的散射槽,最后将组件装上边框,将留出的正、负极接入接线盒,即得防眩光太阳能电池组件。 [0016] (d) components cool to be laminated, and after curing, peeled off the mesh, in ETFE crossbar front plate surface structure scattering in a grid slot, and finally the assembly is mounted on the frame, will stay out of positive and negative access to the junction box, that was the glare of the solar cell module. 冷却后直接揭下网格布便在ETFE前板表面形成散射槽,操作步骤十分简单。 Directly Mesh peeled off after cooling scattering groove is formed in the front surface of the plate ETFE, a very simple procedure.

[0017] 作为优选,网格布的网孔大小为2X2~4X4mm,网格布上网线的宽度为0.5~1mm,网格布上网线的厚度为0.2^0.4_。 [0017] Advantageously, the mesh mesh size of 2X2 ~ 4X4mm, Mesh Internet line width is 0.5 ~ 1mm, the thickness of the mesh access lines is 0.2 ^ 0.4_. 层压后,网孔的大小即为相邻散射槽之间的间隔,网格布上网线的宽度即为散射槽的宽度,网格布上网线的厚度即为散射槽的深度。 After lamination, the size of the mesh is the spacing between adjacent scattering grooves, the width of the mesh lines of the Internet is the scattering width of the groove, the thickness of the mesh lines of the Internet is the groove depth of scattering.
