A method to exchange the counterion of cyanine dyes to Δ-TRISPHAT(-) and PF6(-) is presented. The influence of these counterions on the photophysical and electrochemical properties of the cyanine dye in solution is discussed, and tendencies in the solid packing are highlighted by X-ray crystal structures. The compounds were applied in semitransparent bilayer organic solar cells together with C60, and a power conversion efficiency of 2.2% was achieved while maintaining a high transparency level in the visible region of 66%.
本文介绍了一种将花菁染料的抗衡离子交换为 Δ-TRISPHAT(-) 和 PF6(-)的方法。讨论了这些抗衡离子对花菁染料在溶液中的光物理和电化学性质的影响，并通过 X 射线晶体结构突出了它们在固态堆积中的趋势。这些化合物与 C60 一起应用于半透明双层有机太阳能电池中，在可见光区域 66%的高透明度水平下实现了 2.2%的功率转换效率。
