A series of new organic dyes, comprising a naphthyl moiety as a π‐conjugated bridge, different amines as donors, and a cyanoacrylic acid group as an electron acceptor and anchoring group, have been designed and synthesized for applications in dye‐sensitized solar cells (DSSCs). One of the compounds was also characterized by single‐crystal X‐ray structural analysis. All of the dyes exhibited maximum
已设计并合成了一系列新的有机染料,它们被用于染料敏化太阳能电池(包括:萘基部分作为π共轭桥,不同的胺作为供体以及氰基丙烯酸基团作为电子受体和锚定基团)( DSSC)。其中一种化合物的特征还在于单晶X射线结构分析。所有染料在371–441 nm范围内均表现出最大吸收。设备的短路光电流密度,开路电压和填充因子(FF)值在6.13–10.90 mA cm -2的范围内分别为0.62-0.69 V和0.62-0.67,对应的总转换效率为2.76-4.55%。转换效率达到了在类似条件下制造和测量的基于N719的设备(7.31%)的转换效率的38-62%。萘基和芳族部分之间的立体拥挤危害了电荷从供体向受体的转移。烯基实体在萘基和芳环之间的插入减轻了空间拥挤并导致更长波长的电子吸收光谱。
