With respect to N3, a champion sensitizer in dye-sensitized solar cells (DSSCs), S3 which contained a phenTz (1,10-phenanthroline 5-tetrazole) ancillary ligand showed outstanding improvements in molar extinction coefficient () from 10 681.8 to 12 954.5 M cm as well as 0.92% and 0.9% increases in power conversion efficiency (PCE) and incident photon-to-electron conversion efficiency (IPCE), reaching 8.46% and 76.5%, respectively. To find the origin of the high performance of the DSSC based on a phenTz ancillary ligand, transient absorption spectroscopy (TA) was carried out and indicated that the rate of the regeneration reaction is about 100 times faster than the rate of recombination with the dye which is very exciting and surely a good reason to promote the phenTz ligand as a promising ancillary ligand in DSSCs.
关于N3（染料敏化太阳能电池（DSSC）中的一种出色敏化剂），含有phenTz（1,10 - 菲咯啉 - 5 - 四氮唑）辅助配体的S3，其摩尔消光系数（）从10681.8显著提高到12954.5 M cm，功率转换效率（PCE）和入射光子 - 电子转换效率（IPCE）分别提高了0.92%和0.9%，分别达到8.46%和76.5%。为了找出基于phenTz辅助配体的DSSC高性能的根源，进行了瞬态吸收光谱（TA）研究，结果表明再生反应速率比与染料复合的速率快约100倍，这非常令人兴奋，也肯定是促使phenTz配体成为DSSCs中有前景的辅助配体的一个很好的理由。
