本研究係以溶膠凝膠法配製TiO2溶液,並利用旋轉塗佈機將其塗佈在ITO導電玻璃上,製作成一多孔性薄膜電極。以不同熱處理溫度及不同塗佈層數之TiO2薄膜來探討溫度、膜厚分別對轉換效率的影響,在650℃/三層TiO2薄膜之染料敏化太陽電池其轉換效率達到1.71 %。在碘濃度為0.1M時為此實驗電解液之最佳參數,另外TiO2薄膜電極通過4-叔丁基吡啶的處理,染料敏化太陽能電池之轉換效率較未處理電極高出了13%。 The TiO2 solution was made by sol-gel method in this research. The mesoporous TiO2 film was grown on ITO glass by spin coater via layer-by-layer deposition. The influence of heat treatment temperature and TiO2 film thickness on conversion efficiency was discussed here. The conversion efficiency of DSSC with three-layers TiO2 film treated at 650℃ is 1.71 %. 0.1M of iodide was optimized parameter of electrolyte in this research. Furthermore, the TiO2 film gave a higher conversion efficiency than the TiO2 film nontreated by 4-tertbutylpyridine, which increased 13% by surface treatment with 4-tertbutylpyridine.
