Abstract

A novel class of near-infrared absorbing squarylium sensitizers with linearly extended π-conjugated structures, which were obtained by Pd-catalyzed cross-coupling reactions with stannylcyclobutenediones, has been developed for dye-sensitized solar cells. The cells based on these dyes exhibited a significant spectral response in the near-infrared region over 750 nm in addition to the visible region.

摘要

一类新型的近红外吸收方酸菁敏化剂具有线性扩展的π共轭结构，是通过钯催化的锡杂环丁二酮的交叉偶联反应得到的，用于染料敏化太阳能电池。基于这些染料的电池在可见区域之外的 750nm 以上的近红外区域显示出显著的光谱响应。
