Effect of Peripheral Substitution on the Performance of Subphthalocyanines in DSSCs

Abstract

A series of six new subphthalocyanines (SubPcs) bearing an ethynylcarboxyphenyl anchoring unit and decorated with a variety of substituents at the peripheral position of the macrocycle have been synthesized in order to investigate the effect of the peripheral substituent on the performance of dye-sensitized solar cells.
