安徽光伏發電板(ban)多少錢一平米-烈(lie)陽(yang)質量(liang)可靠(kao)(在線咨詢)

光(guang)伏(fu)發(fa)(fa)電(dian)(dian)能(neng)夠與建筑物相結合，形成(cheng)光(guang)伏(fu)建筑一體(ti)化(hua)的系統，減少土地資源(yuan)的浪費(fei)。歷史(shi)(shi)與現狀太(tai)陽(yang)能(neng)光(guang)伏(fu)發(fa)(fa)電(dian)(dian)的歷史(shi)(shi)可以追溯到1839年法(fa)國(guo)物理(li)學(xue)家(jia)貝克勒爾首1次發(fa)(fa)現光(guang)伏(fu)效應。此后(hou)，各國(guo)科學(xue)家(jia)不斷(duan)探索，1954年塊實用光(guang)伏(fu)電(dian)(dian)池問世(shi)，這意味著太(tai)陽(yang)能(neng)光(guang)伏(fu)發(fa)(fa)電(dian)(dian)逐(zhu)步(bu)進入產業化(hua)發(fa)(fa)展的道路(lu)。進入21世(shi)紀，太(tai)陽(yang)能(neng)電(dian)(dian)池向全球擴展，成(cheng)為一種(zhong)重(zhong)要的可再生能(neng)源(yuan)。

光伏效應：

如(ru)果光(guang)線照射在太(tai)陽能電(dian)(dian)(dian)(dian)(dian)池上并(bing)且(qie)光(guang)在界面(mian)層被(bei)吸收，具有足夠能量的(de)(de)光(guang)子(zi)能夠在P型硅(gui)和(he)(he)N型硅(gui)中將(jiang)電(dian)(dian)(dian)(dian)(dian)子(zi)從共價鍵中激發，以致產生(sheng)(sheng)電(dian)(dian)(dian)(dian)(dian)子(zi)-空穴對。界面(mian)層附近的(de)(de)電(dian)(dian)(dian)(dian)(dian)子(zi)和(he)(he)空穴在復合之前，將(jiang)通(tong)過(guo)空間電(dian)(dian)(dian)(dian)(dian)荷的(de)(de)電(dian)(dian)(dian)(dian)(dian)場作用被(bei)相互(hu)分(fen)離。電(dian)(dian)(dian)(dian)(dian)子(zi)向帶正電(dian)(dian)(dian)(dian)(dian)的(de)(de)N區和(he)(he)空穴向帶負(fu)電(dian)(dian)(dian)(dian)(dian)的(de)(de)P區運動(dong)。通(tong)過(guo)界面(mian)層的(de)(de)電(dian)(dian)(dian)(dian)(dian)荷分(fen)離，將(jiang)在P區和(he)(he)N區之間產生(sheng)(sheng)一個向外的(de)(de)可測試的(de)(de)電(dian)(dian)(dian)(dian)(dian)壓(ya)。此時可在硅(gui)片的(de)(de)兩邊(bian)加上電(dian)(dian)(dian)(dian)(dian)極并(bing)接入電(dian)(dian)(dian)(dian)(dian)壓(ya)表(biao)。對晶體(ti)硅(gui)太(tai)陽能電(dian)(dian)(dian)(dian)(dian)池來(lai)說(shuo)，開路電(dian)(dian)(dian)(dian)(dian)壓(ya)的(de)(de)典型數值為0.5～0.6V。通(tong)過(guo)光(guang)照在界面(mian)層產生(sheng)(sheng)的(de)(de)電(dian)(dian)(dian)(dian)(dian)子(zi)－空穴對越(yue)多，電(dian)(dian)(dian)(dian)(dian)流越(yue)大(da)。界面(mian)層吸收的(de)(de)光(guang)能越(yue)多，界面(mian)層即電(dian)(dian)(dian)(dian)(dian)池面(mian)積越(yue)大(da)，在太(tai)陽能電(dian)(dian)(dian)(dian)(dian)池中形(xing)成的(de)(de)電(dian)(dian)(dian)(dian)(dian)流也越(yue)大(da)。
