It is composed of solar cells or different specifications of solar cells cut by laser cutting machine or steel wire cutting machine.

光伏组件的构成及各部分功能

Composition and functions of PV modules

1.钢化玻璃。其作用为保护发电主体（如电池片），透光其选用是有要求的，透光率须高（一般91%以上）；超白钢化处理

1. Tempered glass. Its function is to protect the main body of power generation (such as battery). The selection of light transmission is required, and the light transmission rate must be high (generally more than 91%); Ultrawhite steel treatment

2.EVA。用来粘结固定钢化玻璃和发电主体（如电池片），透明EVA材质的优劣直接影响到组件的寿命，暴露在空气中的EVA易老化发黄，从而影响组件的透光率，从而影响组件的发电质量除了EVA本身的质量外，组件厂家的层压工艺影响也是非常大的，如EVA胶连度不达标，EVA与钢化玻璃、背板粘接强度不够，都会引起EVA提早老化，影响组件寿命。

2.EVA。 It is used to bond and fix tempered glass and power generation main body (such as battery panel). The quality of transparent EVA material directly affects the service life of the module. EVA exposed to the air is prone to aging and yellowing, thus affecting the light transmittance of the module, thus affecting the power generation quality of the module. In addition to the quality of EVA itself, the lamination process of the module manufacturer also has a great impact, such as the adhesion of EVA is not up to standard, and the adhesion strength between EVA and tempered glass and back plate is not enough, Will cause premature aging of EVA and affect the service life of components.

3.电池片。主要作用就是发电，发电主体市场上主流的是晶体硅太阳电池片、薄膜太阳能电池片，两者各有优劣晶体硅太阳能电池片,设备成本相对较低，但消耗及电池片成本很高，但光电转换效率也高，在室外阳光下发电比较适宜薄膜太阳能电池，相对设备成本较高，但消耗和电池成本很低，但光电转化效率相对晶体硅电池片一半多点，但弱光效应非常好，在普通灯光下也能发电，如计算器上的太阳能电池。

3. Battery slice. The main role is to generate electricity. The mainstream of the power generation market is crystalline silicon solar cells and thin film solar cells, both of which have advantages and disadvantages. The equipment cost is relatively low, but the consumption and cell cost is high, but the photoelectric conversion efficiency is also high. It is more suitable for thin film solar cells to generate electricity in the outdoor sun. The relative equipment cost is high, but the consumption and cell cost is low, However, the photoelectric conversion efficiency is more than half of that of crystalline silicon cells, but the weak light effect is very good. It can also generate electricity under ordinary light, such as solar cells on calculators.

4.背板。作用是密封、绝缘、防水（一般都用TPT、TPE等材质须耐老化，大部分组件厂家质保都是25年，钢化玻璃，铝合金一般都没问题，关键就在与背板和硅胶是否能达到要求。）

4. Back plate. The function is to seal, insulate and waterproof (TPT, TPE and other materials are generally used to resist aging, and most component manufacturers have a 25-year warranty. Tempered glass and aluminum alloy are generally OK. The key is whether the back plate and silicone can meet the requirements.)

5.铝合金。保护层压件，起一定的密封、支撑作用

5. Aluminum alloy. Protect laminated parts and play a certain role in sealing and supporting

6.接线盒保护整个发电系统，起到电流中转站的作用，如果组件短路接线盒自动断开短路电池串，防止烧坏整个系统接线盒中关键的是二极管的选用，根据组件内电池片的类型不同，对应的二极管也不相同

6. The junction box protects the entire power generation system and acts as a current transfer station. If the module short circuit junction box automatically disconnects the short circuit battery string to prevent burning out of the whole system junction box, the key is the selection of diodes. The corresponding diodes are different according to the type of battery in the module

7.硅胶。密封作用，用来密封组件与铝合金边框、组件与接线盒交界处有些公司使用双面胶条、泡棉来替代硅胶，国内普遍使用硅胶，工艺简单，方便，易操作，而且成本很低。

7. Silicone. The sealing function is used to seal the junction between the module and the aluminum alloy frame, and between the module and the junction box. Some companies use double-sided adhesive strips and foam to replace the silica gel. The silica gel is widely used in China. The process is simple, convenient, easy to operate, and the cost is very low.
