| 中文摘要 | 染料敏化太陽能電池(DSSC) 因其成本效益、透明度、靈活性等而受到廣泛的研究關注。 開發銅電解質[Cu(dmodmbp)2]+/2+ 來取代已廣泛用於DSSC的碘電解質，旨在最大限度地減少填充因子 (FF) 的損失。 DA2 染料受先前報告的 LC4 和 LC5 染料結構的啟發，結合兩者的受體來增強光吸收並增加短路電流 (JSC)。這些創新帶來了高效的 DSSC，其功率轉換效率 (PCE) 高達 10.2% (JSC = 12.10 mA·cm2)、開路電壓 (VOC) = 1.11 V、FF = 0.764）以及出色的光穩定性。經過95天的測試表明，可以維持初始PCE的88%，其中VOC、JSC和FF分別保留初始值的98%、97%和93%。 |
| 英文摘要 | Dye-sensitized solar cells (DSSCs) have garnered significant research attention for their cost-effectiveness, transparency, flexibility, etc. In this work, a copper complex of a bipyridine-modified mediator, [Cu(dmodmbp)2]+/2+, is developed to minimize the loss in fill factor (FF). A DA2 dye, inspired by the structures of previously reported LC4 and LC5 dyes, incorporates cascade acceptors to enhance light absorption and increase the short-circuit current (JSC). These innovations lead to highly efficient DSSCs with an impressive power conversion efficiency (PCE) of 10.2% (JSC = 12.10 mA·cm2), open-circuit voltage (VOC) = 1.11 V, FF = 0.764) as well as a remarkable photostability. A test over 95 days shows that 88% of the initial PCE can be maintained, with VOC, JSC, and FF retaining 98%, 97%, and 93% of their initial values, respectively. |
