Abstract
(Figure Presented) Two new organic dyes adopting coplanar diphenyl-substituted dithienosilole as the central linkage have been synthesized, characterized, and used as the sensitizers for dye-sensitized solar cells (DSSCs). The best DSSC exhibited a high power conversion efficiency up to 7.6% (TP6CADTS) under AM 1.5G irradiation, reaching ∼96% of the ruthenium dye N719-based reference cell under the same conditions. © 2010 American Chemical Society.
