太陽(yang)能光伏發電

太(tai)陽(yang)(yang)(yang)能(neng)是(shi)清潔的能(neng)源，太(tai)陽(yang)(yang)(yang)電池(chi)(chi)是(shi)利用光(guang)(guang)(guang)電轉換(huan)原(yuan)理(li)使(shi)太(tai)陽(yang)(yang)(yang)的輻射光(guang)(guang)(guang)通(tong)過半導體物質轉變為電能(neng)的一種新型的器件。太(tai)陽(yang)(yang)(yang)電池(chi)(chi)又稱為“光(guang)(guang)(guang)伏電池(chi)(chi)”，太(tai)陽(yang)(yang)(yang)電池(chi)(chi)經過串并聯后進行封裝保護(hu)可形成(cheng)大面積的太(tai)陽(yang)(yang)(yang)電池(chi)(chi)組件，配上(shang)功(gong)率(lv)控制器、儲能(neng)裝置、變換(huan)器等就(jiu)組成(cheng)了光(guang)(guang)(guang)伏發電系(xi)統。太(tai)陽(yang)(yang)(yang)能(neng)電池(chi)(chi)發電原(yuan)理(li)是(shi)光(guang)(guang)(guang)生伏打(da)效應(ying)，故太(tai)陽(yang)(yang)(yang)能(neng)電池(chi)(chi)也叫光(guang)(guang)(guang)伏電池(chi)(chi)。

在太(tai)(tai)(tai)陽(yang)(yang)能(neng)(neng)(neng)(neng)發電(dian)(dian)系統(tong)中，系統(tong)的(de)(de)總效(xiao)(xiao)(xiao)率(lv)(lv)η由(you)太(tai)(tai)(tai)陽(yang)(yang)能(neng)(neng)(neng)(neng)電(dian)(dian)池(chi)組(zu)件(jian)的(de)(de)光(guang)電(dian)(dian)轉(zhuan)換效(xiao)(xiao)(xiao)率(lv)(lv)、控制器效(xiao)(xiao)(xiao)率(lv)(lv)、蓄電(dian)(dian)池(chi)效(xiao)(xiao)(xiao)率(lv)(lv)、逆變器效(xiao)(xiao)(xiao)率(lv)(lv)及(ji)負載的(de)(de)效(xiao)(xiao)(xiao)率(lv)(lv)等決(jue)定。目前，太(tai)(tai)(tai)陽(yang)(yang)能(neng)(neng)(neng)(neng)電(dian)(dian)池(chi)的(de)(de)光(guang)電(dian)(dian)轉(zhuan)換效(xiao)(xiao)(xiao)率(lv)(lv)只有17%左右(you)。因此，提高太(tai)(tai)(tai)陽(yang)(yang)能(neng)(neng)(neng)(neng)電(dian)(dian)池(chi)組(zu)件(jian)的(de)(de)光(guang)電(dian)(dian)轉(zhuan)換效(xiao)(xiao)(xiao)率(lv)(lv)、降(jiang)低太(tai)(tai)(tai)陽(yang)(yang)能(neng)(neng)(neng)(neng)光(guang)伏(fu)發電(dian)(dian)系統(tong)的(de)(de)單位(wei)功率(lv)(lv)造價，是太(tai)(tai)(tai)陽(yang)(yang)能(neng)(neng)(neng)(neng)光(guang)伏(fu)發電(dian)(dian)產業化(hua)的(de)(de)重點(dian)和(he)難(nan)點(dian)。自(zi)太(tai)(tai)(tai)陽(yang)(yang)能(neng)(neng)(neng)(neng)電(dian)(dian)池(chi)問世以來，晶體(ti)硅作為(wei)主(zhu)要材料保持著統(tong)治地(di)位(wei)。目前對硅太(tai)(tai)(tai)陽(yang)(yang)能(neng)(neng)(neng)(neng)電(dian)(dian)池(chi)轉(zhuan)換效(xiao)(xiao)(xiao)率(lv)(lv)的(de)(de)研(yan)究，主(zhu)要圍繞著加大(da)吸(xi)能(neng)(neng)(neng)(neng)面、運用吸(xi)雜技術和(he)鈍化(hua)工藝提高硅太(tai)(tai)(tai)陽(yang)(yang)能(neng)(neng)(neng)(neng)電(dian)(dian)池(chi)的(de)(de)轉(zhuan)換效(xiao)(xiao)(xiao)率(lv)(lv)、電(dian)(dian)池(chi)超薄型化(hua)等方面。

太(tai)(tai)陽(yang)能(neng)(neng)(neng)光(guang)伏(fu)(fu)發電(dian)(dian)(dian)是利用太(tai)(tai)陽(yang)電(dian)(dian)(dian)池的(de)(de)(de)光(guang)生伏(fu)(fu)特1效應直接把太(tai)(tai)陽(yang)的(de)(de)(de)輻射(she)能(neng)(neng)(neng)轉(zhuan)變為(wei)電(dian)(dian)(dian)能(neng)(neng)(neng)的(de)(de)(de)一種發電(dian)(dian)(dian)方式，太(tai)(tai)陽(yang)能(neng)(neng)(neng)光(guang)伏(fu)(fu)發電(dian)(dian)(dian)的(de)(de)(de)能(neng)(neng)(neng)量轉(zhuan)換器就是太(tai)(tai)陽(yang)能(neng)(neng)(neng)電(dian)(dian)(dian)池，也叫光(guang)伏(fu)(fu)電(dian)(dian)(dian)池。太(tai)(tai)陽(yang)光(guang)照射(she)到太(tai)(tai)陽(yang)電(dian)(dian)(dian)池上時，其中(zhong)一部分光(guang)線被反射(she), 一部分光(guang)線被吸(xi)收， 還有一部分光(guang)線透過電(dian)(dian)(dian)磁(ci)片。被吸(xi)收的(de)(de)(de)光(guang) 能(neng)(neng)(neng)激(ji)發被束(shu)縛(fu)的(de)(de)(de)高能(neng)(neng)(neng)級(ji)狀態下的(de)(de)(de)電(dian)(dian)(dian)子(zi)，產生電(dian)(dian)(dian)子(zi)-空(kong)穴對(dui)，在PN結(jie)的(de)(de)(de)內建(jian)電(dian)(dian)(dian)場作(zuo)用下，電(dian)(dian)(dian)子(zi)，空(kong)穴相互(hu)運(yun)動(dong)N區的(de)(de)(de)空(kong)穴向P區運(yun)動(dong)，P區的(de)(de)(de)電(dian)(dian)(dian)子(zi)向N區運(yun)動(dong)，他太(tai)(tai)陽(yang)電(dian)(dian)(dian)池的(de)(de)(de)受光(guang)面有大量負電(dian)(dian)(dian)荷積(ji)累，而在電(dian)(dian)(dian)池的(de)(de)(de)背光(guang)面有大量正電(dian)(dian)(dian)荷積(ji)累。
