藉由對光電極進行二階段熱處理方式可以增進染料敏化太陽能電池(Dye-sensitized Solar Cell, DSSC)光電轉換效能。第一階段於氧氣中熱處理能夠有效地移除殘留於TiO2中的有機物質,促使染料順利地吸附在TiO2上,並提升電池的光電流密度。不過,此階段因為熱處理過程中氛圍中的氧原子填補ITO (Indium tin oxide, ITO)薄膜內的氧空缺,會使ITO導電薄膜片電阻從5.18 Ω/□大幅上升至32.2 Ω/□。第二階段熱處理於氮氣下目的是為了將第一階段於氧氣下熱處理時填補ITO薄膜結構中的氧原子帶走,使得ITO內的氧空缺數量增加,以降低ITO薄膜的片電阻並且提升染敏電池的填充效率。
我們對經過不同熱處理後的ITO導電薄膜進行光電性質、結構、表面型態、表面組成進行分析。ITO薄膜在含氧環境下熱處理其電阻會急遽上升,但在第二階段於氮氣中熱處理後電阻有下降的現象,因為電阻的高低與薄膜內的氧空缺數量有關。ITO薄膜於可見光範圍內的平均透光度在熱處理後仍然可以維持80%以上。經由熱處理後ITO薄膜結晶性會比熱處理前佳,因為非化學計量比(Non-stoichiometric compositions)的氧化物在熱處理中充分被氧化成化學計量比的氧化物,但於第二階段熱處理後的氧原子被帶走,故其結晶性又會變差。表面組成的分析中,結果顯示經過第一階段的熱處理後氧原子含量增加,而在第二階段熱處理後,氧原子含量有減少的趨勢。
由於光電流密度及填充效率的提升,轉換效率從傳統的一階段熱處理方式的5.53 %躍升至二階段式熱處理方式的6.7 %,光電流密度從14.08 mA/cm2上升至15.90 mA/cm2。
