Abstract

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. Abstract : It′s about performance : A series of six new subphthalocyanines (SubPcs) with different peripheral substituents have been synthesized and their performances as photosensitizers in DSSC evaluated. SubPc4 having octylthioether substituents gave rise to an efficiency four times higher than that of SubPc1 bearing electron‐withdrawing octylsulfonyl groups. This work emphasizes the importance of the peripheral substitution of SubPcs on their photovoltaic performances in DSSCs.
