光伏組(zu)件(jian)(jian)(jian)的(de)背板材(cai)料(liao)正適合封裝(zhuang)太(tai)陽能電(dian)池組(zu)件(jian)(jian)(jian)，作(zuo)為(wei)(wei)電(dian)池組(zu)件(jian)(jian)(jian)的(de)背板材(cai)料(liao)有(you)效地(di)防止了各種介質尤其是水(shui)、氧(yang)、腐蝕性氣體等對EVA和太(tai)陽能電(dian)池片(pian)的(de)侵蝕與影響。光伏組(zu)件(jian)(jian)(jian)框架的(de)主要(yao)材(cai)料(liao)有(you)不(bu)銹鋼(gang)、鋁(lv)合金(jin)、橡膠及增強(qiang)塑料(liao)等。常規光伏框架一般(ban)是鋁(lv)材(cai)料(liao)制(zhi)作(zuo)的(de)。光伏組(zu)件(jian)(jian)(jian)中單晶(jing)(jing)硅片(pian)由于四個角(jiao)均為(wei)(wei)弧形(xing)，所以封裝(zhuang)成(cheng)為(wei)(wei)組(zu)件(jian)(jian)(jian)之后單晶(jing)(jing)組(zu)件(jian)(jian)(jian)會有(you)留白，會有(you)大約3%的(de)封裝(zhuang)損失(shi)。而多晶(jing)(jing)硅片(pian)為(wei)(wei)的(de)正方形(xing)，不(bu)存(cun)在這方面的(de)封裝(zhuang)損失(shi)，這使得多晶(jing)(jing)組(zu)件(jian)(jian)(jian)一定(ding)程度上(shang)彌補了效率。
