光伏組件的構(gòu)成及各部分功能

Composition and functions of PV modules

1.鋼化玻璃。其作用為保護(hù)發(fā)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(lái)粘結(jié)固定鋼化玻璃和發(fā)電主體（如電池片），透明EVA材質(zhì)的優(yōu)劣直接影響到組件的壽命，暴露在空氣中的EVA易老化發(fā)黃，從而影響組件的透光率，從而影響組件的發(fā)電質(zhì)量除了EVA本身的質(zhì)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(dá)標(biāo)，EVA與鋼化玻璃、背板粘接強(qiáng)度不夠，都會(huì)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(fā)電，發(fā)電主體市場(chǎng)上主流的是晶體硅太陽(yáng)電池片、薄膜太陽(yáng)能電池片，兩者各有優(yōu)劣晶體硅太陽(yáng)能電池片,設(shè)備成本相對(duì)較低，但消耗及電池片成本很高，但光電轉(zhuǎn)換效率也高，在室外陽(yáng)光下發(fā)電比較適宜薄膜太陽(yáng)能電池，相對(duì)設(shè)備成本較高，但消耗和電池成本很低，但光電轉(zhuǎn)化效率相對(duì)晶體硅電池片一半多點(diǎn)，但弱光效應(yīng)非常好，在普通燈光下也能發(fā)電，如計(jì)算器上的太陽(yáng)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(zhì)須耐老化，大部分組件廠家質(zhì)保都是25年，鋼化玻璃，鋁合金一般都沒問(wèn)題，關(guān)鍵就在與背板和硅膠是否能達(dá)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(hù)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(hù)整個(gè)發(fā)電系統(tǒng)，起到電流中轉(zhuǎn)站的作用，如果組件短路接線盒自動(dòng)斷開短路電池串，防止燒壞整個(gè)系統(tǒng)接線盒中關(guān)鍵的是二極管的選用，根據(jù)組件內(nèi)電池片的類型不同，對(duì)應(yīng)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(lái)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(lái)替代硅膠，國(guó)內(nèi)普遍使用硅膠，工藝簡(jiǎn)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.
