本(ben)申請涉(she)及太(tai)陽能(neng)電(dian)池(chi),具體涉(she)及一種電(dian)池(chi)組(zu)件及其制備方法、太(tai)陽能(neng)電(dian)池(chi)。
背景技術:
1、鈣鈦礦(kuang)(kuang)太陽能(neng)電池因(yin)為(wei)其潛(qian)在的高效率、低(di)成本(ben)優勢(shi),作為(wei)第三代(dai)光(guang)伏技(ji)術備(bei)受關(guan)注。相對于晶硅太陽能(neng)電池,鈣鈦礦(kuang)(kuang)太陽能(neng)電池的大面積制(zhi)備(bei)工(gong)藝更加簡單(dan)高效。通(tong)常將鈣鈦礦(kuang)(kuang)太陽能(neng)電池劃分為(wei)電池單(dan)元(cell),并采用(yong)串聯的方(fang)式將多個(ge)電池單(dan)元連接,實現功率輸出。
2、然而,由于各個電(dian)池單(dan)元(yuan)串聯(lian)拼接(jie)處(chu)為死(si)(si)區結(jie)構(gou),死(si)(si)區結(jie)構(gou)無法進行光電(dian)轉(zhuan)換,導致鈣鈦礦太陽能電(dian)池的功率(lv)轉(zhuan)換效率(lv)(power?conversion?efficiency,pce)較(jiao)低。
