Abstract
Two new organic dyes, WS-2.1 and WS-2.2—derivatives of the known dye WS-2—are computationally designed using a recently developed approach with a broad absorption peak at around 775 nm in acetonitrile for WS-2.2 versus 610 nm for WS-2. The red shift includes a significant contribution due to vibrations and is not reproduced by standard computational methods. The oxidation and reduction potentials of the dye render it well suited for use in dye-sensitized solar cells.
