本研究主要是探討,染料敏化太陽能電池(dye-sensitized solar cell, DSSC),以PAN有機高分子為主體的膠態電解質,並以不同比例的溶劑的電解質來測量,其對太陽能電池的效率,而本實驗將LiI、I2作為到電解質的原料,在溶劑方面是利用PC、EC比例的不同來進行比較,在光陽極方面則是採用刀刮塗佈法(Doctor-Blade Method, DB)與旋轉塗佈法(Slit and Spin Coating)方法來製作,在旋轉塗佈方面,以轉速不同對厚度的影響來進行太陽光效率的比較,染料方面使用化學染料N719,加入電解質,使其具有氧化還原對,作為染料敏化太陽能電池中電解質的應用。在封裝後形成三明治結構 (sandwich structure),最後將染料敏化太陽能電池,進行光電轉換效率(solar energy-to-electricity conversion efficiency)的測試實驗,經由檢測的結果發現,當PAN20wt%以及在溶劑EC:PC=8:2時所得到的光電轉換效率最高,並利用旋轉塗佈法在500rpm下以及在光陽極TiO2漿料加入X100,並可得到最佳光電轉換效率3.58%。

This study’s main focus is on dye-sensitized solar cell (DSSC) using PAN organic particles as the main body of the gelled electrolyte, and also using different combinations of solvents to measure its efficiency towards solar cell. This experiment used LiI and I2 as raw material to produce the electrolytes. and used different ratios of PC and EC as solvents to compare the results. The study selected Doctor-Blade(DB) method and Slit and Spin Coating methods to produce photo-anodes at different rotation speeds to show the effect that different thicknesses of film has and to measure its efficiency. For the dye, this research used chemical dye N719 and added electrolytes to it to enable it to redox, also as an application of electrolytes on dye-sensitive solar cell. Finally the cell was packed into a sandwich structure, and photoelectric conversion efficiency conversion efficiency tests were performed on the dye-sensitive solar cell. The result of the tests showed that when PAN is 20wt% and the combination of EC and PC at the ratio of 8:2 has the greatest photoelectric conversion efficiency conversion efficiency; the experiment used Spin Coating methods rotating at 500rpm to produce photo-electrode; also, by adding X100 into the photo-electrode of TiO2 pastes the experiment achieved the greatest photoelectric conversion efficiency of 3.58%.
