天合藍天光伏組件指具有封裝及內部聯結的，能單獨提供直流電輸出的，不可分割的光伏電池組合裝置，由太陽能電池片或由激光切割機機或鋼線切割機切割開的不同規格的太陽能電池組合在一起構成。

Trina Solar PV module refers to an indivisible photovoltaic cell combination device with packaging and internal connection, which can provide DC power output separately. It is composed of solar cells or different specifications of solar cells cut by laser cutting machine or steel wire cutting machine.

光伏組件的構成及各部分功能

Composition and functions of PV modules

1.鋼化玻璃。其作用為保護發電主體（如電池片），透光其選用是有要求的，透光率須高（一般91%以上）；超白鋼化處理

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。用來粘結固定鋼化玻璃和發電主體（如電池片），透明EVA材質的優劣直接影響到組件的壽命，暴露在空氣中的EVA易老化發黃，從而影響組件的透光率，從而影響組件的發電質量除了EVA本身的質量外，組件廠家的層壓工藝影響也是非常大的，如EVA膠連度不達標，EVA與鋼化玻璃、背板粘接強度不夠，都會引起EVA提早老化，影響組件壽命。

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.電池片。主要作用就是發電，發電主體市場上主流的是晶體硅太陽電池片、薄膜太陽能電池片，兩者各有優劣晶體硅太陽能電池片,設備成本相對較低，但消耗及電池片成本很高，但光電轉換效率也高，在室外陽光下發電比較適宜薄膜太陽能電池，相對設備成本較高，但消耗和電池成本很低，但光電轉化效率相對晶體硅電池片一半多點，但弱光效應非常好，在普通燈光下也能發電，如計算器上的太陽能電池。

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、絕緣、防水（一般都用TPT、TPE等材質須耐老化，大部分組件廠家質保都是25年，鋼化玻璃，鋁合金一般都沒問題，關鍵就在與背板和硅膠是否能達到要求。）

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.鋁合金。保護層壓件，起一定的密封、支撐作用

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

6.接線盒保護整個發電系統，起到電流中轉站的作用，如果組件短路接線盒自動斷開短路電池串，防止燒壞整個系統接線盒中關鍵的是二極管的選用，根據組件內電池片的類型不同，對應的二極管也不相同

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.硅膠。密封作用，用來密封組件與鋁合金邊框、組件與接線盒交界處有些公司使用雙面膠條、泡棉來替代硅膠，國內普遍使用硅膠，工藝簡單，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.
