The creation of organic dyes with excellent high power conversion efficiency (PCE) is important for the further improvement of dye‐sensitized solar cells. We wish to describe the rapid synthesis of a 112‐membered donor‐π‐acceptor dye library by a one‐pot procedure, evaluation of PCEs, and elucidation of structure–property relationships. No obvious correlations between ε, and the η were observed, whereas
具有出色的高功率转换效率(PCE)的有机染料的产生对于进一步改善染料敏化太阳能电池非常重要。我们希望描述通过一锅法,PCE的评估以及结构与属性之间关系的阐明来快速合成112个成员的供体π受体染料库。没有观察到ε与η之间有明显的相关性,而染料的HOMO和LUMO水平对于η至关重要。具有更高的E HOMO阳性和E LUMO <-0.80 V的染料具有更高的PCE。适当的驱动力对于高J sc至关重要,它是高η时最重要的参数。E HOMO和E LUMO的上述标准对于创建高PCE染料应该是有用的。然而,这不足以确定供体,π和受体嵌段的最佳组合。组合合成和评估对于确定最佳染料很重要。
