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。一般采用單晶硅(gui)(gui)、多晶硅(gui)(gui)和非晶硅(gui)(gui)等半導(dao)體材料。單(dan)晶硅太陽(yang)(yang)(yang)能(neng)(neng)電池(chi)是(shi)當前(qian)開發得最快的(de)一種(zhong)太陽(yang)(yang)(yang)能(neng)(neng)電池(chi),它的(de)構造和(he)生產工藝已(yi)定型,產品已(yi)廣泛(fan)用(yong)(yong)于空(kong)間(jian)和(he)地面(mian)。這種(zhong)太陽(yang)(yang)(yang)能(neng)(neng)電池(chi)以高純(chun)的(de)單(dan)晶硅棒為原料(liao)(liao)。為了降低生產成本,地面(mian)應用(yong)(yong)的(de)太陽(yang)(yang)(yang)能(neng)(neng)電池(chi)等采用(yong)(yong)太陽(yang)(yang)(yang)能(neng)(neng)級(ji)的(de)單(dan)晶硅棒,材(cai)料(liao)(liao)性(xing)能(neng)(neng)指標有所放(fang)寬。有的(de)也可使用(yong)(yong)半導體器(qi)件加(jia)工的(de)頭尾料(liao)(liao)和(he)廢(fei)次單(dan)晶硅材(cai)料(liao)(liao),經過復拉(la)制成太陽(yang)(yang)(yang)能(neng)(neng)電池(chi)專用(yong)(yong)的(de)單(dan)晶硅棒。
二、電池片的種類和作用
1、太陽能電池片
在(zai)太(tai)(tai)陽能電池(chi)產品(pin)(pin)中,以(yi)硅(gui)半(ban)導體材料(liao)(liao)為主,其中又以(yi)單晶(jing)(jing)硅(gui)和多晶(jing)(jing)硅(gui)為代表。由于(yu)其原材料(liao)(liao)的(de)(de)廣泛性(xing)(xing)(xing),較(jiao)高的(de)(de)轉(zhuan)換效率和可靠(kao)性(xing)(xing)(xing),被(bei)市(shi)(shi)場廣泛接受(shou)。非晶(jing)(jing)硅(gui)在(zai)民用(yong)產品(pin)(pin)上(shang)也有廣泛的(de)(de)應用(yong)(如電子手表,計算器等),但是(shi)(shi)它的(de)(de)穩定(ding)性(xing)(xing)(xing)和轉(zhuan)換效率劣于(yu)結晶(jing)(jing)類半(ban)導體材料(liao)(liao)。化(hua)合物(wu)太(tai)(tai)陽能電池(chi)由于(yu)其材料(liao)(liao)的(de)(de)稀有性(xing)(xing)(xing)和部分材料(liao)(liao)具(ju)有公(gong)害,現階段未被(bei)市(shi)(shi)場廣泛采用(yong)。太(tai)(tai)陽能電池(chi)的(de)(de)主流產品(pin)(pin)的(de)(de)材料(liao)(liao)是(shi)(shi)半(ban)導體硅(gui),是(shi)(shi)現代電子工業的(de)(de)必不(bu)可少的(de)(de)材料(liao)(liao),同時以(yi)氧化(hua)狀態的(de)(de)硅(gui)原料(liao)(liao)是(shi)(shi)世(shi)界上(shang)第(di)二大的(de)(de)儲藏物(wu)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(yao)控(kong)器電(dian)(dian)池(chi)片(pian)(pian)(pian)(pian)(pian)、電(dian)(dian)池(chi)接(jie)觸片(pian)(pian)(pian)(pian)(pian)、電(dian)(dian)池(chi)彈簧(huang)片(pian)(pian)(pian)(pian)(pian)、電(dian)(dian)池(chi)扣、鍋(guo)仔片(pian)(pian)(pian)(pian)(pian)、接(jie)觸片(pian)(pian)(pian)(pian)(pian)、彈片(pian)(pian)(pian)(pian)(pian)、彈簧(huang)片(pian)(pian)(pian)(pian)(pian)、電(dian)(dian)池(chi)夾片(pian)(pian)(pian)(pian)(pian),電(dian)(dian)極(ji)片(pian)(pian)(pian)(pian)(pian)。主要用(yong)于遙(yao)控(kong)器、電(dian)(dian)子玩具、計算(suan)器、計步器、麥克(ke)風、電(dian)(dian)話機(ji)、錄音機(ji)、收音機(ji)、音響、照相機(ji)、燈飾等行業。
