Abstract

Association between cationic and anionic heptamethine dyes led to the formation of a new organic salt (3) displaying exceptional light-harvesting properties in the NIR spectral range and having amphoteric redox character. Preliminary results of molecular bulk heterojunction solar cells based on the title compound 3 and [60]PCBM as the only active layer reveal this new dye as a promising light-harvesting material for photovoltaics.

摘要

阳离子和阴离子七甲川染料之间的缔合导致形成了一种新的有机盐（3），该有机盐在近红外光谱范围内表现出优异的光捕获性能，并具有两性氧化还原特性。基于标题化合物3和[60]PCBM作为唯一活性层的分子体异质结太阳能电池的初步结果表明，这种新染料是一种有前途的用于光伏的光捕获材料。
