將一個負載連接在太(tai)陽(yang)能(neng)電(dian)(dian)池的(de)(de)上下兩(liang)表面間時，將有電(dian)(dian)流流過該負載，于是(shi)太(tai)陽(yang)能(neng)電(dian)(dian)池 就產生(sheng)(sheng)了電(dian)(dian)流；太(tai)陽(yang)能(neng)電(dian)(dian)池吸收的(de)(de)光子越多(duo)，產生(sheng)(sheng)的(de)(de)電(dian)(dian)流也就越大。應用(yong)領(ling)(ling)域，交(jiao)通(tong)(tong)領(ling)(ling)域：如航標(biao)燈、交(jiao)通(tong)(tong)/鐵(tie)路信號燈、交(jiao)通(tong)(tong)警示/標(biao)志燈、宇翔路燈、高空(kong)障礙(ai)燈、高速公路/鐵(tie)路無線電(dian)(dian)話(hua)亭、無人值守道班供電(dian)(dian)等。光伏組(zu)件(jian)中光伏玻璃鋼(gang)化處理是(shi)為了增加玻璃的(de)(de)強(qiang)(qiang)度，抵御(yu)風沙冰雹(bao)的(de)(de)沖擊，起到長期(qi)保護太(tai)陽(yang)能(neng)電(dian)(dian)池的(de)(de)作用(yong)。對面板玻璃進行鋼(gang)化處理后，玻璃的(de)(de)強(qiang)(qiang)度可比(bi)普通(tong)(tong)玻璃提高3～4倍。

太(tai)陽(yang)(yang)(yang)能(neng)電池(chi)(chi)組(zu)件(jian)(jian)(jian)也(ye)叫太(tai)陽(yang)(yang)(yang)能(neng)光伏(fu)組(zu)件(jian)(jian)(jian)，鹽城太(tai)陽(yang)(yang)(yang)能(neng)組(zu)件(jian)(jian)(jian)，通(tong)常還簡稱為電池(chi)(chi)板(ban)或光伏(fu)組(zu)件(jian)(jian)(jian)。太(tai)陽(yang)(yang)(yang)能(neng)電池(chi)(chi)組(zu)件(jian)(jian)(jian)是把(ba)多(duo)個單體的(de)(de)太(tai)陽(yang)(yang)(yang)能(neng)電池(chi)(chi)片(pian)根(gen)據需要串并聯起(qi)來，并通(tong) 過材(cai)料和(he)(he)專門生產(chan)工(gong)藝進行封(feng)裝后的(de)(de)產(chan)品。光伏(fu)組(zu)件(jian)(jian)(jian)的(de)(de)背板(ban)材(cai)料中白(bai)色的(de)(de)復合膜(mo)還可(ke)對陽(yang)(yang)(yang)光起(qi)反射作(zuo)(zuo)用，光伏(fu)組(zu)件(jian)(jian)(jian)太(tai)陽(yang)(yang)(yang)能(neng)，能(neng)提高電池(chi)(chi)組(zu)件(jian)(jian)(jian)的(de)(de)轉換(huan)效率，且(qie)對紅(hong)外線也(ye)有較(jiao)強(qiang)的(de)(de)反射，可(ke)降低電池(chi)(chi)組(zu)件(jian)(jian)(jian)在強(qiang)陽(yang)(yang)(yang)光下的(de)(de)工(gong)作(zuo)(zuo)溫度。太(tai)陽(yang)(yang)(yang)能(neng)電池(chi)(chi)組(zu)件(jian)(jian)(jian)中要加入(ru)兩層(ceng)EVA膠膜(mo)，兩層(ceng)EVA膠膜(mo)夾在面(mian)板(ban)玻璃(li)、電池(chi)(chi)片(pian)和(he)(he)TPT背板(ban)膜(mo)之間，將玻璃(li)、電池(chi)(chi)片(pian)和(he)(he)TPT黏合在一起(qi)。它(ta)和(he)(he)玻璃(li)黏合后能(neng)提高玻璃(li)的(de)(de)透光率，并對太(tai)陽(yang)(yang)(yang)能(neng)電池(chi)(chi)組(zu)件(jian)(jian)(jian)功率輸出有增益(yi)作(zuo)(zuo)用。
