在氣候(hou)變暖(nuan)、全球能源危機嚴重威脅(xie)到經(jing)濟(ji)發展和(he)人(ren)們的生活狀況下。清潔、環保、可再生的太陽能日益引起了世界的廣泛(fan)關注。

太陽能電池里極為重要的一(yi)個零部件——NTC熱敏電(dian)阻(zu)，它是直接(jie)影響太陽能電(dian)池的(de)轉(zhuan)換效率及生命周期的(de)一(yi)個重要(yao)參數指標。NTC熱敏電阻里采用的是金/銀熱敏芯片，具(ju)有性(xing)(xing)價比高(gao)，高(gao)穩(wen)定(ding)(ding)性(xing)(xing)、高(gao)可靠性(xing)(xing)，體(ti)積小、快速反應等特(te)性(xing)(xing)，這些特(te)性(xing)(xing)可以(yi)使得太陽能電(dian)池(chi)更加穩(wen)定(ding)(ding)及高(gao)效。

太陽能電(dian)池發電(dian)的原理：太陽能電池是利用半導體材料的光電效應,將太陽能(neng)(neng)(neng)(neng)(neng)轉換成電(dian)(dian)(dian)(dian)能(neng)(neng)(neng)(neng)(neng)的(de)(de)(de)裝(zhuang)置(zhi).光(guang)生伏特效應:假設(she)光(guang)線照射在(zai)(zai)(zai)太陽能(neng)(neng)(neng)(neng)(neng)電(dian)(dian)(dian)(dian)池(chi)(chi)上并且光(guang)在(zai)(zai)(zai)界(jie)面(mian)(mian)(mian)層(ceng)(ceng)(ceng)被(bei)(bei)接(jie)納，具有足夠能(neng)(neng)(neng)(neng)(neng)量的(de)(de)(de)光(guang)子(zi)(zi)可(ke)以在(zai)(zai)(zai)P型(xing)硅(gui)(gui)和(he)N型(xing)硅(gui)(gui)中(zhong)(zhong)(zhong)將電(dian)(dian)(dian)(dian)子(zi)(zi)從共價鍵中(zhong)(zhong)(zhong)激起，致使(shi)發(fa)作電(dian)(dian)(dian)(dian)子(zi)(zi)-空穴(xue)對(dui)。界(jie)面(mian)(mian)(mian)層(ceng)(ceng)(ceng)臨近的(de)(de)(de)電(dian)(dian)(dian)(dian)子(zi)(zi)和(he)空穴(xue)在(zai)(zai)(zai)復合之前(qian)，將經(jing)由空間電(dian)(dian)(dian)(dian)荷的(de)(de)(de)電(dian)(dian)(dian)(dian)場結果被(bei)(bei)相(xiang)互分別(bie)。電(dian)(dian)(dian)(dian)子(zi)(zi)向帶正電(dian)(dian)(dian)(dian)的(de)(de)(de)N區(qu)和(he)空穴(xue)向帶負電(dian)(dian)(dian)(dian)的(de)(de)(de)P區(qu)運(yun)動。經(jing)由界(jie)面(mian)(mian)(mian)層(ceng)(ceng)(ceng)的(de)(de)(de)電(dian)(dian)(dian)(dian)荷分別(bie)，將在(zai)(zai)(zai)P區(qu)和(he)N區(qu)之間發(fa)作一(yi)個向外的(de)(de)(de)可(ke)測試(shi)的(de)(de)(de)電(dian)(dian)(dian)(dian)壓(ya)。此時可(ke)在(zai)(zai)(zai)硅(gui)(gui)片的(de)(de)(de)兩邊(bian)加上電(dian)(dian)(dian)(dian)極并接(jie)入電(dian)(dian)(dian)(dian)壓(ya)表(biao)。對(dui)晶體硅(gui)(gui)太陽能(neng)(neng)(neng)(neng)(neng)電(dian)(dian)(dian)(dian)池(chi)(chi)來說(shuo)，開路電(dian)(dian)(dian)(dian)壓(ya)的(de)(de)(de)典型(xing)數(shu)值(zhi)為0.5~0.6V。經(jing)由光(guang)照在(zai)(zai)(zai)界(jie)面(mian)(mian)(mian)層(ceng)(ceng)(ceng)發(fa)作的(de)(de)(de)電(dian)(dian)(dian)(dian)子(zi)(zi)-空穴(xue)對(dui)越多，電(dian)(dian)(dian)(dian)流越大(da)。界(jie)面(mian)(mian)(mian)層(ceng)(ceng)(ceng)接(jie)納的(de)(de)(de)光(guang)能(neng)(neng)(neng)(neng)(neng)越多，界(jie)面(mian)(mian)(mian)層(ceng)(ceng)(ceng)即電(dian)(dian)(dian)(dian)池(chi)(chi)面(mian)(mian)(mian)積(ji)越大(da)，在(zai)(zai)(zai)太陽能(neng)(neng)(neng)(neng)(neng)電(dian)(dian)(dian)(dian)池(chi)(chi)中(zhong)(zhong)(zhong)組成的(de)(de)(de)電(dian)(dian)(dian)(dian)流也越大(da)。  

溫度(du)(du)也是(shi)作為一(yi)個太(tai)陽能電池(chi)組的(de)重要指標。對太(tai)陽能電池(chi)組件的(de)發電效率與溫度(du)(du)控制(zhi)是(shi)一(yi)個關(guan)鍵組件，NTC熱敏電阻就(jiu)是起(qi)(qi)到(dao)(dao)了(le)對太陽能電池溫(wen)度的溫(wen)度監(jian)測和監(jian)控。從而有效地對產品(pin)起(qi)(qi)到(dao)(dao)了(le)保(bao)護的作(zuo)用。
