We report a blue dye, coded as R6, which features a polycyclic aromatic hydrocarbon, 9,19-dihydrobenzo[1',10']phenanthro[3',4':4,5]thieno[3,2-b]benzo[1,10]phenanthro[3,4-d]thiophene, coupled with a diarylamine electron donor and 4-(7-ethynylbenzo[c][1,2,5]thiadiazol-4-yl)benzoic acid acceptor. Dye R6 displays a brilliant sapphire color in a sensitized TiO mesoporous film with a Co(II/III) tris(bipyridyl)-based redox electrolyte. The R6 based dye-sensitized solar cell achieves an impressive power conversion efficiency of 12.6% under standard air mass 1.5 global, 100 mW cm, and shows a remarkable photostability.
我们报告了一种蓝色染料，编码为 R6，它具有多环芳烃，9,19-二氢苯并[1',10']菲咯[3',4':4,5]噻吩[3,2-b]苯并[1,10]菲咯[3,4-d]噻吩，与二芳基胺电子供体和 4-(7-乙炔基苯并[c][1,2,5]噻二唑-4-基)苯甲酸受体偶联。R6 染料在敏化 TiO 介孔膜中显示出绚丽的蓝宝石色，其中包含 Co(II/III)三(联吡啶)-基氧化还原电解质。基于 R6 的染料敏化太阳能电池在标准空气质量 1.5 全球、100 mW cm 下实现了令人印象深刻的 12.6%功率转换效率，并表现出出色的光稳定性。
