| 中文摘要 | 兩個具有蒽官能基之新型染料DY1及DY2可應用於染敏太陽能電池，DY1具有一個羧酸基，DY2具有兩個羧酸基，在一個太陽光的條件下，DY1光電轉換效率的表現為5.71%，DY2的表現為6.96%略高於DY1的結果，在電池穩定性的測試上，DY2的穩定性也優於DY1，這樣的結果可反映兩個羧酸基在電池穩定性的貢獻。 |
| 英文摘要 | Two dyes of DY1 and DY2 featuring 1,2-di(anthracene-9-yl)ethyne as an extended π-conjugated spacer and an N, N-diarylamino group as the donor have been designed and synthesized for application in dye-sensitized solar cell. On the other side of 1,2-di(anthracene-9-yl)ethyne, DY1 contains one carboxylic acid as the anchoring group at 10-position of anthracene whereas structural analogs DY2 has dual carboxylic acid groups at 4, 5-positions of anthracene as the anchors for binding to TiO2. With the introduction of the dual carboxyl anchors, the higher dipole moment of the molecule may induce relatively high local I- concentration at the interface to reduce the oxidized dye (D+), thus DY2-based device has the highest short-circuit current (JSC). For open-circuit voltage (VOC), both of DY1 and DY2-based devices have close VOC owing to their structures resemble CW6. For DY2-based device, the power conversion efficiency of DSCs achieved h= 6.96% under simulated one-sun AM 1.5 G illumination with JSC = 13.08 mA cm-2, VOC = 0.73 V, FF = 0.73, which is considerably higher than that of DY1-based device with h = 5.71%, JSC = 10.70 mA cm-2, VOC = 0.72 V, and FF = 0.74, whereas the reference dye CW6 exhibited a cell performance of h = 6.96%, JSC = 11.50 mA cm-2, VOC = 0.78 V and FF = 0.78. Besides, dual anchoring dye, DY2-based device performed better stability than the others. |
