Abstract

XS1-XS3 have been synthesized by introducing an auxiliary acceptor into D-π-A dyes for simultaneous filling up of both absorption valleys of porphyrin dyes at around 550 and 380 nm. Thus, panchromatic DSSCs with the highest efficiency of 10.75% were achieved by cosensitization. This work provides a strategy for designing cosensitizers for porphyrin dyes.
