本研究的目的是在非常低的強度條件（VLIC）調查染料敏化太陽能電池（DSSC）的光學和電學性質。為了測試的DSSC的溫度和濕度試驗後的效果，被選定為混合二氧化鈦，使DSSC樣品一些不同的染料N719和Z907。在我們的實驗中，樣品的溫度和濕度試驗使用魏斯SB22 / 160進行測試。溫度和濕度的試驗條件設定RH.The DSSC樣品的電性能通過使用一個IV曲線測得50℃/ 75％RH，65℃/ 85％RH，70℃/ 75％RH和85℃/ 85％儀表。光輻射條件被設定在非常低強度條件（VLIC：60瓦/平方米），這是用於在低光強度輻射應用定義。從具有和不具有溫度和濕度試驗DSSC（N719色素）的我們的測試JV曲線，所述的Voc，Jsc為FF和前DSSC樣品的效率的溫度和濕度試驗是0.779V，15（毫安/厘米2），64％和6.4 ％分別與開路電壓，Jsc為FF和DSSC樣品的效率被降解到0.779V，9.56（毫安/厘米2），70％和4.58％分別後20小時溫度和濕度測試。還從DSSC（Z907染料）的使用和不使用的溫度和濕度試驗合營曲線，所述的Voc，Jsc為FF和前DSSC樣品的效率的溫度和濕度試驗是0.628V，12.15（毫安/厘米2），67％和5.14 ％分別與開路電壓，Jsc為FF和DSSC樣品的效率被降解到0.655V，6.06（毫安/厘米2），67％和2.67％分別15小時後的溫度和濕度測試。在一般情況下，DSSC染料樣品的光學和電學性質後的溫度和濕度試驗100小時明顯降解。（DSSC）是一種具有高的潛在應用與一個低成本的太陽能電池。本研利用照光老化試驗與恆溫恆濕試驗來探討DSSC光學和電學性質，使用兩種不同的染料為N719和Z907製作為DSSC樣品，染料樣品的吸收光譜使用UV / VIS吸收光譜儀進行量測，DSSC樣品透過電化學分析儀量測樣品電性。照光老化試驗分別為每20小時將樣品取出，並量測電性量測與染料的吸收光譜量測作為一個循環。電性量測採用的是一般太陽能電池量測標準測試條件，條件為Air mass 1.5 (AM 1.5) Global spectrum，1000 W/m-2，25℃。量測結果顯示照光老化20小時後，N719 樣品效率明顯下降，而N719樣品在照光老化達80小時後其轉換效率下降幅度達21%；Z907樣品在照光老化40小時後效率為最大值，照光老化到達80小時後Z907樣品轉換效率下降幅度達13%，兩者結果顯示Z907相較於N719在嚴苛的環境之下耐久度較高。

The purpose of this study is to investigate the optical and electrical properties of dye sensitized solar cell (DSSC) at very low intensity condition (VLIC). In order to test the effect of the DSSC after temperature and humidity test, some different dyes N719 and Z907 were selected for mixing TiO2 to make DSSC samples. In our experiment, the temperature and humidity test of sample was tested by using Weiss SB22/160. The testing conditions of temperature and humidity were set 50℃/75%RH, 65℃/85%RH, 70℃/75%RH and 85℃/85%RH.The electrical properties of DSSC samples were measured by using an I-V curve meter. The light radiation condition was set at the very low intensity condition (VLIC: 60 W/m2), which is defined for applications in low light intensity radiation. From our testing J-V curves of DSSC (N719 dye) with and without temperature and humidity test, the Voc, Jsc, FF and efficiency of DSSC sample before temperature and humidity test are 0.779V, 15(mA/cm2), 64% and 6.4% respectively, and the Voc, Jsc, FF and efficiency of DSSC sample are degraded to 0.779V, 9.56(mA/cm2), 70% and 4.58% respectively after 20 hour temperature and humidity test. Also from the J-V curves of DSSC (Z907 dye) with and without temperature and humidity test, the Voc, Jsc, FF and efficiency of DSSC sample before temperature and humidity test are 0.628V, 12.15(mA/cm2), 67% and 5.14% respectively, and the Voc, Jsc, FF and efficiency of DSSC sample are degraded to 0.655V, 6.06(mA/cm2), 67% and 2.67% respectively after 15 hours temperature and humidity test. In general, the optical and electrical properties of DSSC dye samples are degraded obviously after temperature and humidity test for 100 hours.
