hyperchromic effects in these complexes compared with Z907 (cis‐[RuLL′(NCS)2]; L=4,4′‐dicarboxylic acid‐2,2′‐bipyridine, L′=4,4′‐dinonyl‐2,2′‐ bipyridine). The long hydrocarbon chains help to suppress the dark current if appropriately disposed. DSSCs that use these complexes exhibit very impressive conversion efficiencies (5.94 to 6.91 %) that surpass that of Z907‐based (6.36 %) DSSCs and are comparable
已经合成了新的杂合钌络合物,并用作染料敏化太阳能电池(DSSC)的敏化剂。辅助联吡啶配体包含刚性芳族链段(芴-,咔唑-或双硫杂[3,2- b:2',3'- d ]吡咯取代的联吡啶),并带有疏水己基取代基。与Z907(顺-[Ru LL'(NCS)2 ]; L = 4,4'-二羧酸-2,2'-联吡啶,L'= 4,4'-二壬基-2,2'-联吡啶)。如果适当处理,长烃链有助于抑制暗电流。使用这些复合物的DSSC表现出非常出色的转化效率(5.94至6.91%),超过了基于Z907的DSSC(6.36%),并且与基于N719的标准电池(7.13%;N719 =顺式di(thiocyanato)双(2,2'-联吡啶-4-4,4'-二羧基芳基)钌(II)双(四丁基铵))在相似的条件下(有效面积:0.5×0.5 cm 2 ; AM 1.5阳光)制造和测量。
