Abstract

Four novel 1,3-dithiol-2-ylidene dyes BDY-1, BDY-2, BDY-3, and BDY-4 were developed for dye-sensitized solar cells. Among these dyes, BDY-4 containing a 9,9-dibutyl-9H-fluorene spacer and a phenyl group at the vinyl position showed the highest efficiency (3.26%), indicating the importance of the phenyl substituent and the fluorene unit in improving the efficiency.
