探針臺系統太陽能電池的特性表征測試方案

概述

對太(tai)(tai)(tai)陽(yang)能(neng)電(dian)(dian)(dian)(dian)池(chi)進(jin)行電(dian)(dian)(dian)(dian)流-電(dian)(dian)(dian)(dian)壓(ya)(I-V)特性分析對推導有關其性能(neng)的(de)(de)重要參數(shu)至關重要，包括最大(da)(da)電(dian)(dian)(dian)(dian)流(Imax)和電(dian)(dian)(dian)(dian)壓(ya)(Vmax)、開路電(dian)(dian)(dian)(dian)壓(ya)(Voc)、短路電(dian)(dian)(dian)(dian)流(Isc)以及效率(η)。多(duo)組太(tai)(tai)(tai)陽(yang)能(neng)電(dian)(dian)(dian)(dian)池(chi)IV測(ce)(ce)試(shi)(shi)系統方案(an)使(shi)用國際(ji)標準AAA級別太(tai)(tai)(tai)陽(yang)能(neng)模擬器取代傳統的(de)(de)鹵(lu)素燈，氙燈等光源，能(neng)夠(gou)完(wan)全(quan)模擬太(tai)(tai)(tai)空和地面的(de)(de)太(tai)(tai)(tai)陽(yang)能(neng)光譜(pu)，解決(jue)了(le)實驗室測(ce)(ce)試(shi)(shi)太(tai)(tai)(tai)陽(yang)能(neng)電(dian)(dian)(dian)(dian)池(chi)入射光譜(pu)的(de)(de)匹配問題;而電(dian)(dian)(dian)(dian)池(chi)IV特性測(ce)(ce)試(shi)(shi)儀器采用Keithley的(de)(de)高精(jing)度源測(ce)(ce)量單(dan)元SMU，從100fA到10A超(chao)寬光電(dian)(dian)(dian)(dian)流和暗電(dian)(dian)(dian)(dian)流測(ce)(ce)量能(neng)力，能(neng)夠(gou)覆蓋絕大(da)(da)多(duo)數(shu)電(dian)(dian)(dian)(dian)池(chi)功率測(ce)(ce)試(shi)(shi)。結(jie)合精(jing)密多(duo)路切換開關和針對客戶電(dian)(dian)(dian)(dian)池(chi)電(dian)(dian)(dian)(dian)極形狀的(de)(de)定制化(hua)夾具，可實現最高60路電(dian)(dian)(dian)(dian)池(chi)單(dan)元的(de)(de)連續IV測(ce)(ce)試(shi)(shi)，大(da)(da)大(da)(da)提高了(le)測(ce)(ce)試(shi)(shi)精(jing)度、重復(fu)性、效率。

英鉑科學儀器的測試(shi)方案通過CycleStar軟(ruan)件可(ke)對(dui)(dui)每(mei)個電池(chi)(chi)單元(yuan)獨立(li)或(huo)順(shun)序IV特性測試(shi)，顯示IV特性曲線(xian)和(he)(he)Isc, Voc, Pmax, FF, η和(he)(he)電池(chi)(chi)表(biao)面(mian)溫(wen)度等參數，每(mei)個電池(chi)(chi)單元(yuan)測試(shi)結果可(ke)以(yi)保(bao)存(cun)在一(yi)個EXCEL文件中(zhong)，可(ke)進行對(dui)(dui)電池(chi)(chi)表(biao)面(mian)均勻性分布進行統計分析(xi)。
