概述

      對(dui)太(tai)陽(yang)(yang)能(neng)(neng)電(dian)(dian)(dian)池進行電(dian)(dian)(dian)流(liu)-電(dian)(dian)(dian)壓(I-V)特性(xing)分析對(dui)推(tui)導有關(guan)其性(xing)能(neng)(neng)的(de)(de)(de)(de)重(zhong)要(yao)參(can)數(shu)(shu)至關(guan)重(zhong)要(yao)，包括最大(da)(da)電(dian)(dian)(dian)流(liu)(Imax)和(he)電(dian)(dian)(dian)壓(Vmax)、開路(lu)電(dian)(dian)(dian)壓(Voc)、短路(lu)電(dian)(dian)(dian)流(liu)(Isc)以及效率(lv)(η)。多(duo)組太(tai)陽(yang)(yang)能(neng)(neng)電(dian)(dian)(dian)池IV測試(shi)系統(tong)方案(an)使(shi)用(yong)(yong)國際標準AAA級別太(tai)陽(yang)(yang)能(neng)(neng)模擬(ni)器取代傳統(tong)的(de)(de)(de)(de)鹵素燈(deng)，氙燈(deng)等光(guang)源，能(neng)(neng)夠完全模擬(ni)太(tai)空和(he)地(di)面的(de)(de)(de)(de)太(tai)陽(yang)(yang)能(neng)(neng)光(guang)譜(pu)，解決了實驗(yan)室(shi)測試(shi)太(tai)陽(yang)(yang)能(neng)(neng)電(dian)(dian)(dian)池入射光(guang)譜(pu)的(de)(de)(de)(de)匹配問題;而電(dian)(dian)(dian)池IV特性(xing)測試(shi)儀器采用(yong)(yong)Keithley的(de)(de)(de)(de)高(gao)(gao)精度源測量單(dan)元SMU，從100fA到(dao)10A超寬光(guang)電(dian)(dian)(dian)流(liu)和(he)暗電(dian)(dian)(dian)流(liu)測量能(neng)(neng)力，能(neng)(neng)夠覆(fu)蓋絕大(da)(da)多(duo)數(shu)(shu)電(dian)(dian)(dian)池功率(lv)測試(shi)。結合精密多(duo)路(lu)切換開關(guan)和(he)針對(dui)客戶電(dian)(dian)(dian)池電(dian)(dian)(dian)極形狀(zhuang)的(de)(de)(de)(de)定制(zhi)化夾具，可實現高(gao)(gao)達60路(lu)電(dian)(dian)(dian)池單(dan)元的(de)(de)(de)(de)連續IV測試(shi)，大(da)(da)大(da)(da)提高(gao)(gao)了測試(shi)精度、重(zhong)復(fu)性(xing)、效率(lv)。

      英鉑科學(xue)儀(yi)器的(de)測試(shi)方案通過CycleStar軟件可(ke)(ke)(ke)對(dui)(dui)每個(ge)電(dian)池單(dan)元(yuan)獨立或順序IV特(te)性測試(shi)，顯示IV特(te)性曲(qu)線和Isc, Voc, Pmax, FF, η和電(dian)池表面溫度等參數(shu)，每個(ge)電(dian)池單(dan)元(yuan)測試(shi)結果可(ke)(ke)(ke)以保存在(zai)一個(ge)EXCEL文件中(zhong)，可(ke)(ke)(ke)進行對(dui)(dui)電(dian)池表面均勻性分(fen)(fen)布進行統計分(fen)(fen)析。
