一、電池片是什么材料做的
電池片是利用光電材料吸收光能后發生光電于轉換反應來進行發電的。一般采用單晶(jing)硅(gui)(gui)、多晶(jing)硅(gui)(gui)和非(fei)晶(jing)硅(gui)(gui)等半導體材料。單晶(jing)硅太陽(yang)(yang)(yang)(yang)(yang)能(neng)電(dian)(dian)(dian)(dian)池(chi)是(shi)當前開發得最(zui)快的一種太陽(yang)(yang)(yang)(yang)(yang)能(neng)電(dian)(dian)(dian)(dian)池(chi),它的構造和(he)生(sheng)產(chan)(chan)(chan)工藝已定型,產(chan)(chan)(chan)品已廣泛(fan)用(yong)于空間(jian)和(he)地(di)面(mian)。這種太陽(yang)(yang)(yang)(yang)(yang)能(neng)電(dian)(dian)(dian)(dian)池(chi)以(yi)高純的單晶(jing)硅棒為(wei)(wei)原料(liao)。為(wei)(wei)了降低生(sheng)產(chan)(chan)(chan)成本,地(di)面(mian)應用(yong)的太陽(yang)(yang)(yang)(yang)(yang)能(neng)電(dian)(dian)(dian)(dian)池(chi)等采用(yong)太陽(yang)(yang)(yang)(yang)(yang)能(neng)級的單晶(jing)硅棒,材(cai)料(liao)性能(neng)指標有所放寬。有的也可(ke)使用(yong)半導體器(qi)件加工的頭尾料(liao)和(he)廢(fei)次(ci)單晶(jing)硅材(cai)料(liao),經(jing)過(guo)復拉制成太陽(yang)(yang)(yang)(yang)(yang)能(neng)電(dian)(dian)(dian)(dian)池(chi)專用(yong)的單晶(jing)硅棒。
二、電池片的種類和作用
1、太陽能電池片
在太(tai)陽(yang)(yang)能(neng)電(dian)池(chi)產(chan)品中(zhong),以(yi)硅半導體(ti)材(cai)料(liao)(liao)為主(zhu)(zhu),其中(zhong)又以(yi)單晶硅和(he)(he)多晶硅為代表(biao)。由于(yu)其原材(cai)料(liao)(liao)的(de)(de)(de)廣(guang)泛(fan)性,較高(gao)的(de)(de)(de)轉換(huan)效率和(he)(he)可(ke)靠(kao)性,被市場廣(guang)泛(fan)接(jie)受。非(fei)晶硅在民用(yong)產(chan)品上也有(you)廣(guang)泛(fan)的(de)(de)(de)應用(yong)(如電(dian)子(zi)手表(biao),計算器等),但是它(ta)的(de)(de)(de)穩定性和(he)(he)轉換(huan)效率劣于(yu)結晶類半導體(ti)材(cai)料(liao)(liao)。化合物太(tai)陽(yang)(yang)能(neng)電(dian)池(chi)由于(yu)其材(cai)料(liao)(liao)的(de)(de)(de)稀(xi)有(you)性和(he)(he)部分材(cai)料(liao)(liao)具有(you)公害(hai),現階段未被市場廣(guang)泛(fan)采用(yong)。太(tai)陽(yang)(yang)能(neng)電(dian)池(chi)的(de)(de)(de)主(zhu)(zhu)流產(chan)品的(de)(de)(de)材(cai)料(liao)(liao)是半導體(ti)硅,是現代電(dian)子(zi)工業(ye)的(de)(de)(de)必不(bu)可(ke)少的(de)(de)(de)材(cai)料(liao)(liao),同時以(yi)氧化狀態的(de)(de)(de)硅原料(liao)(liao)是世界上第(di)二(er)大的(de)(de)(de)儲藏物質。
2、五金電池片
五金電池片主要是導電作用。還稱:電池片、遙控器(qi)(qi)電(dian)池(chi)片(pian)(pian)(pian)、電(dian)池(chi)接觸片(pian)(pian)(pian)、電(dian)池(chi)彈簧(huang)片(pian)(pian)(pian)、電(dian)池(chi)扣(kou)、鍋仔片(pian)(pian)(pian)、接觸片(pian)(pian)(pian)、彈片(pian)(pian)(pian)、彈簧(huang)片(pian)(pian)(pian)、電(dian)池(chi)夾片(pian)(pian)(pian),電(dian)極片(pian)(pian)(pian)。主要用于遙控器(qi)(qi)、電(dian)子玩具、計(ji)算(suan)器(qi)(qi)、計(ji)步器(qi)(qi)、麥克(ke)風、電(dian)話機(ji)(ji)(ji)、錄音機(ji)(ji)(ji)、收音機(ji)(ji)(ji)、音響、照相機(ji)(ji)(ji)、燈(deng)飾等行(xing)業。
