用于染料敏化太阳能电池的包含线性平面11,12-二氢吲哚并[2,3- a ]咔唑供体的新型无金属有机染料:π间隔基和烷基链的作用
摘要:
成功设计并合成了三种新型D-π-A型染料DC1〜3,它们由吲哚[2,3- a ]咔唑作为供体骨架,通过不同的π-间隔与受体/固定单元氰乙酸连接。详细研究了三种敏化剂的结构,光物理和电化学性质以及光伏性质。结果表明,具有两个支链烷基链的供体11,12-双(2-乙基己基)-11,12-二氢吲哚[2,3- a ]咔唑可有效抑制分子间π-π聚集作用,并具有辅助作用。 π桥中的烷基链导致基于DC3的DSSC的开路电压高于基于染料的器件的开路电压DC2。在所有用染料制成的器件中,不含鹅去氧胆酸(CDCA)的DC3基电池表现出最佳的光伏性能,短路电流密度为10.98 mA cm -2,开路电压为752 mV,且填充系数为0.725,对应于液态电解质的最高功率转换效率为5.98%。

Two push–pull D–π–A molecules, 3T and DTT as donor materials, were synthesized and characterized for solution-processed bulk heterojunction (BHJ) organicphotovoltaic (OPV) devices. The π-linker plays a vital role not only in electrochemical and thermal properties but also affects the thin film morphology of 3T and DTT. 3T showed the high electrochemical stability with a faster electrode reaction rate
