厚(hou)度為 0. 5mm的(de)EVA膜層(ceng)作為太(tai)陽(yang)電(dian)(dian)池(chi)的(de)密封劑和(he)(he)與玻璃(li)、TPT之間的(de)連接(jie)劑。具有(you)較高的(de)透光(guang)率和(he)(he)抗老化(hua)能(neng)力。太(tai)陽(yang)能(neng)交流發電(dian)(dian)系統(tong)是由(you)太(tai)陽(yang)電(dian)(dian)池(chi)板、充電(dian)(dian)控制器、逆變器和(he)(he)蓄電(dian)(dian)池(chi)共同組(zu)成(cheng)；太(tai)陽(yang)能(neng)直流發電(dian)(dian)系統(tong)則不包括逆變器。為了使太(tai)陽(yang)能(neng)發電(dian)(dian)系統(tong)能(neng)為負載提供足夠的(de)電(dian)(dian)源，就要根據用電(dian)(dian)器的(de)功率，合理選擇各部件(jian)。光(guang)伏組(zu)件(jian)中光(guang)伏玻璃(li)鋼化(hua)處(chu)理是為了增加玻璃(li)的(de)強度，光(guang)伏組(zu)件(jian)廠(chang)家(jia)，抵御風沙冰雹的(de)沖擊，起到長期保護太(tai)陽(yang)能(neng)電(dian)(dian)池(chi)的(de)作用。對面板玻璃(li)進行鋼化(hua)處(chu)理后，玻璃(li)的(de)強度可(ke)比普通玻璃(li)提高3～4倍。

太(tai)陽(yang)能(neng)(neng)電(dian)(dian)(dian)池組(zu)(zu)件(jian)(jian)中要加(jia)入兩層(ceng)EVA膠膜，兩層(ceng)EVA膠膜夾在面板(ban)玻(bo)璃、電(dian)(dian)(dian)池片和TPT背板(ban)膜之間，光(guang)伏組(zu)(zu)件(jian)(jian)廠，將(jiang)玻(bo)璃、電(dian)(dian)(dian)池片和TPT黏合(he)在一(yi)起。它和玻(bo)璃黏合(he)后能(neng)(neng)提高玻(bo)璃的(de)透光(guang)率(lv)，并對太(tai)陽(yang)能(neng)(neng)電(dian)(dian)(dian)池組(zu)(zu)件(jian)(jian)功率(lv)輸(shu)出有增益作用。光(guang)伏組(zu)(zu)件(jian)(jian)的(de)背板(ban)材(cai)料正適合(he)封裝太(tai)陽(yang)能(neng)(neng)電(dian)(dian)(dian)池組(zu)(zu)件(jian)(jian)，作為(wei)電(dian)(dian)(dian)池組(zu)(zu)件(jian)(jian)的(de)背板(ban)材(cai)料有效地(di)防止了(le)各種介質尤其是水(shui)、氧(yang)、腐蝕性氣體(ti)等對EVA和太(tai)陽(yang)能(neng)(neng)電(dian)(dian)(dian)池片的(de)侵蝕與影(ying)響。

太(tai)(tai)(tai)陽(yang)(yang)(yang)能(neng)(neng)電(dian)(dian)池(chi)組(zu)件(jian)(jian)也叫太(tai)(tai)(tai)陽(yang)(yang)(yang)能(neng)(neng)光(guang)(guang)伏(fu)組(zu)件(jian)(jian)，通常還(huan)簡稱(cheng)為電(dian)(dian)池(chi)板或(huo)光(guang)(guang)伏(fu)組(zu)件(jian)(jian)。太(tai)(tai)(tai)陽(yang)(yang)(yang)能(neng)(neng)電(dian)(dian)池(chi)組(zu)件(jian)(jian)是把(ba)多個單體的太(tai)(tai)(tai)陽(yang)(yang)(yang)能(neng)(neng)電(dian)(dian)池(chi)片根據需要串(chuan)并(bing)聯起來，并(bing)通 過材料和(he)(he)專門生(sheng)產工(gong)藝進行(xing)封裝后的產品。光(guang)(guang)伏(fu)組(zu)件(jian)(jian)的背板材料中(zhong)白(bai)色的復合膜還(huan)可對(dui)陽(yang)(yang)(yang)光(guang)(guang)起反射作(zuo)用(yong)，能(neng)(neng)提(ti)高電(dian)(dian)池(chi)組(zu)件(jian)(jian)的轉換效率(lv)(lv)，光(guang)(guang)伏(fu)組(zu)件(jian)(jian)生(sheng)產，且對(dui)紅(hong)外線也有(you)較(jiao)強(qiang)的反射，上海光(guang)(guang)伏(fu)組(zu)件(jian)(jian)，可降低(di)電(dian)(dian)池(chi)組(zu)件(jian)(jian)在(zai)強(qiang)陽(yang)(yang)(yang)光(guang)(guang)下的工(gong)作(zuo)溫度(du)。太(tai)(tai)(tai)陽(yang)(yang)(yang)能(neng)(neng)電(dian)(dian)池(chi)組(zu)件(jian)(jian)中(zhong)要加入兩(liang)層(ceng)EVA膠膜，兩(liang)層(ceng)EVA膠膜夾(jia)在(zai)面板玻(bo)璃(li)、電(dian)(dian)池(chi)片和(he)(he)TPT背板膜之(zhi)間，將(jiang)玻(bo)璃(li)、電(dian)(dian)池(chi)片和(he)(he)TPT黏合在(zai)一起。它和(he)(he)玻(bo)璃(li)黏合后能(neng)(neng)提(ti)高玻(bo)璃(li)的透(tou)光(guang)(guang)率(lv)(lv)，并(bing)對(dui)太(tai)(tai)(tai)陽(yang)(yang)(yang)能(neng)(neng)電(dian)(dian)池(chi)組(zu)件(jian)(jian)功率(lv)(lv)輸(shu)出有(you)增益作(zuo)用(yong)。
