光(guang)(guang)伏組件(jian)對晶(jing)硅(gui)電池(chi)組件(jian)背板(ban)的(de)性(xing)能(neng)要求通常包(bao)括：1.具有良好的(de)耐氣候性(xing)能(neng)；2.層壓溫度(du)下不起任何變化。多晶(jing)硅(gui)太陽能(neng)電池(chi)的(de)使用壽命也要比單晶(jing)硅(gui)太陽能(neng)電池(chi)短。從(cong)性(xing)能(neng)價格比來講(jiang)，單晶(jing)硅(gui)太陽能(neng)電池(chi)還略(lve)好。超白布紋鋼(gang)(gang)化玻璃，厚度(du)3.2mm，在太陽電池(chi)光(guang)(guang)譜(pu)響(xiang)應的(de)波長范圍內(nei)(320-1100nm)透(tou)光(guang)(guang)率(lv)達91%以上，耐紫外光(guang)(guang)線的(de)輻射，透(tou)光(guang)(guang)率(lv)不下降。鋼(gang)(gang)化玻璃作(zuo)成的(de)組件(jian)可以承受(shou)直徑25毫米(mi)的(de)冰球以23米(mi)/秒的(de)速度(du)撞擊。
