中文摘要 紫質是是其中一類可作為高效能染料敏化太陽能電池（DSSC）之重要的染料。然而，其由於分子結構設計的缺陷，應用於DSSC的效率相對落後於有機太陽能電池和鈣鈦礦太陽能電池。最近，我們先前報導具有優異光伏性能的雙柵欄卟啉，經由引入八個烷氧基鏈來包裹紫質主體並阻止電解質接近TiO2表面。基於雙柵欄卟啉的設計策略加上二環戊烷並苯二噻吩基團的引入 ，合成了具有雙功能茚並二環戊烷並苯二噻吩基團的新型紫質bJS8、YS2、YS3、YS7和MC1，並研究了它們在DSSC中的光伏性能。在這些新型雙柵紫質染料中，YS7 的光電轉換效率提高了11.4%（短路電流（JSC）= 17.34 mA cm−2，開路電壓（VOC）= 0.864 V，填充因子（FF）= 0.758 ) ）與先前發表的雙柵欄卟啉 bJS2 的 10.7%（JSC = 16.59 mA cm−2，VOC = 0.849 V 和 FF = 0.759）和基準紫質染料 GY50 的 10.1%（JSC = 16.14 mA cm在最佳化條件下（VOC = 0.863 V，FF = 0.725），為DSSC 中高效紫質染料提供了新的分子設計策略。
英文摘要 Porphyrins are an important category of dyes for efficient dye-sensitized solar cells (DSSCs). However, the efficiency improvement of DSSCs lags behind those of organic and perovskite solar cells owing to deficiencies in new design strategies of dye molecular structures. Recently, double fence porphyrins with superior photovoltaic performance were reported, in which eight alkoxyl chains were introduced to wrap the porphyrin core and retard the approach of the electrolyte to the surface of TiO2. On the basis of the design strategy of double fence porphyrins, novel porphyrins bJS8, YS2, YS3, YS7, and MC1 featuring dual functional indacenodithiophene group are synthesized and their photovoltaic performance in DSSCs are studied. Among these new double fence porphyrin dyes, YS7 exhibits an improved power conversion efficiency of 11.4% (short circuit photocurrent (JSC) = 17.34 mA cm−2, open circuit photovoltage (VOC) = 0.864 V, and fill factor (FF) = 0.758) compared to the previously reported double fence porphyrin bJS2 of 10.7% (JSC = 16.59 mA cm−2, VOC = 0.849 V, and FF = 0.759) and the benchmark porphyrin dye GY50 of 10.1% (JSC = 16.14 mA cm−2, VOC = 0.863 V, and FF = 0.725) under optimized conditions, providing a new molecular design strategy for high-efficiency porphyrin dyes in DSSCs.
