Abstract
A new series of stable, unsymmetrical squaraine near-IR sensitizers (JK-216 and JK-217), which are assembled using both thiophenyl pyrrolyl and indolium groups, exhibit a panchromatic light harvesting up to 780 nm. The JK-216 based cell exhibited a record efficiency of 6.29% for near-IR DSSCs. In addition, the JK-217 device showed an excellent stability under a light soaking test at 60 °C for 1000 h.
摘要
一系列新的稳定的、非对称的方酸近红外敏化剂（JK-216 和 JK-217），采用噻吩吡咯基和吲哚基团组装，实现了全光谱的光捕获，可达 780nm。基于 JK-216 的电池在近红外 DSSC 中表现出创纪录的 6.29%的效率。此外，在 60°C 下进行 1000 小时的光浸泡测试后，JK-217 器件表现出优异的稳定性。
