双玻光伏组件介绍About double glazing panel双玻光伏组件，是指由两片玻璃和太阳能电池片组成复合层，电池片之间由导线串、并联汇集到引线端所形成的光伏电池组件。
The utility model relates to a double glass photovoltaic component, which is a composite layer composed of two pieces of glass and a solar battery sheet, wherein, the photovoltaic cells are formed by the connection of the wires in series and in parallel to the lead end of the battery.双玻光伏建筑可以分为BIPV、BAPV两种形式。
BIPV（光伏建筑一体化）是说，光伏组件作为建筑的构件，是建筑的一部分。
它的特点是，除了要满足组件的性能要求以外，还要防火，并满足建筑力学、热舒适、采光、隔音等的一些建筑要求。
BAPV指的是光伏组件作为建筑的一个附件，这一块就相对比较简单，只要满足光伏组件的一些性能要求就可以。
当然，它要跟建筑结合，所以也要做一些防火的测试。
Dual glass photovoltaic architecture can be divided into two forms: BIPV and BAPV. BIPV (photovoltaic building integration) is that photovoltaic components as building components, is part of the building. It is characterized by, in addition to meeting the performance requirements of components, but also fire protection, and meet construction mechanics, thermal comfort, lighting, sound insulation and other architectural requirements. BAPV refers to the PV modules as an annex to the building, this piece is relatively simple, as long as the photovoltaic components meet some of the performance requirements can be. Of course, it should be combined with the building, so it is necessary to do some fire prevention tests.双玻组件可以做成各种颜色。
其次，它可以扩展多种形式，可以加工成中通的结构来隔热，或者隔噪声，还可以做成各种透光率，满足建筑的采光要求。
再次，它结构对称。
这个特点可以说是光伏组件的特点。
比如说，承受静态载荷之后，电力片可以做到无隐裂。
因为晶体硅电池有一个最大的缺点就是非常脆，很容易发生破碎。
但在对称结构当中，它承受外力的时候，可以做到不会破碎，在这种载荷之后，它功率衰减非常小。
这个跟它的力学对称结构是相关的。
它在冷热循环中功率衰减也非常小。
The double glass component can be made into various colors. Secondly, it can be extended in many forms, and can be processed into a medium to pass structure to insulate the heat or noise. It can also be made into all kinds of light transmittance to meet the lighting requirements of the building. Once again, it is structurally symmetrical. This feature can be said to be the characteristics of PV modules. For example, after the static load is applied, the power slice can be cracked free. Because crystalline silicon cells have one of the biggest drawbacks is very brittle, very prone to fragmentation.But in a symmetrical structure, when it is subjected to external forces, it can not be broken, and after such a load, its power attenuation is very small. This is related to its mechanical symmetric structure. It also has very little power attenuation in the hot and cold cycles.在BAPV形式中，它附着在倾斜的屋面的形式，通常是作为建筑的附件，会增加建筑的负荷能力。
它的哪些特点比较适合在BAPV上应用呢？第一，它外表面都是玻璃结构。
玻璃结构抗紫外能力非常强，防火等级也比较高，可以很轻松地做到1500伏的系统电压。
当然，如果你是用1000伏的电压的话，代表了它的绝缘性能非常好，它的安全性会更高。
即便是老化之后的玻璃，绝缘性也非常好。
第二，它没有金属边框，相对普通组件来说，它省去了接地的操作，这样可以避免PID （电位诱发衰减）现象的产生。
当然，我们如果说能够把水膜去掉，能够把在回路过程中的任何一个点打断，同样也不会有PID产生。
没有边框后，组件的工作温度会变低。
同时，它还能防止灰尘的积攒。
第三个特点还是结构对称，对于组件来说依然是在载荷之后电力片无引力，功率衰减小，TC循环过程中功率分解小。
In the form of BAPV, it is attached to an inclined roofing form, usually as an attachment to the building, which increases the load capacity of the building. What are its features suitable for use on BAPV? First, it has a glass structure on its outer surface. The structure of glass is very resistant to UV, and the fire rating is relatively high. It can easily achieve the system voltage of 1500 volts. Of course, if you are using 1000 volts of voltage, it stands for its very good insulation performance, and its security will be higher. Even after aging, the insulation of the glass is very good. Second, it does not have a metal frame, and it eliminates grounding operations relative to the ordinary components, thus avoiding the generation of PID (potential induced attenuation). Of course, if we say that we can remove the water film and interrupt any point in the loop process, there will be no PID.Without a border, the component's operating temperature will be low. At the same time, it can prevent dust accumulation. The third feature is structural symmetry. For the component, it is still in the load, the power sheet has no attraction, the power attenuation is small, and the power decomposition in the TC cycle is small.在没有边框之后，它的工作温度较常规的组件会低2~5摄氏度，发电量高1%~2%，原因是常规组件铝合金边框内部不利于空气的对流。
没有边框之后，对流就会明显加强，造成组件的温度下降。
当组件和屋顶安装的距离非常近的时候，对流是更差，所以双玻组件更适合在斜面屋顶上安装，在这种情况下，它温度的降低会体现的更加明显。
举一个例子，比如有人踩在双玻组件上，电池片本身是有弯曲的，但是电池片本身的程度没有变化。
所以说，电池片又承受了这样一个拉伸和压缩的力，尤其是在拉伸的过程中，电池片非常容易产生引力。
这对于TC循环过程中的道理来说是一样的。
TC代表的是热胀冷缩、温度循环，材料也会发生膨胀和收缩。
对于力学的对称结构来说，对电池片的影响就非常小。
我们在实验室对双玻组件做了一些老化的测试，有高温高湿、冷热循环、PID、紫外线，试验中的条件都是2倍于IEC的标准，UV的话可能就是6倍了。
实验之后，双玻组件的功率衰减值为2%，尤其是PID，基本上小于1%。
