light intensely in the red to near-IR region is important to improve the performance of dye-sensitized solar cells. In this article, three new squaraine sensitizers containing diarylamines with varied alkyl or alkoxyl chain substituents as auxiliary donors were synthesized and utilized. The effects of different donor tail chains, i.e., methyl, methoxyl and hexyloxy groups on the photophysical, electrochemical
开发能够强烈吸收红色至近红外区域光的敏化剂对于提高染料敏化太阳能电池的性能很重要。在本文中,合成并利用了三种新型的方酸敏化剂,它们包含具有不同烷基或烷氧基链取代基的二芳基胺作为辅助供体。研究了不同的供体尾链,即甲基,甲氧基和己氧基对光物理,电化学和光伏性质的影响。结果表明,烷氧基链带来比烷基链更宽的光响应,并且在抑制电子重组方面,长烃链优于短链。因此,具有双(4-(己氧基氧基)苯基)胺取代基,
