Abstract
  • In recent years, metal-free organic sensitizers for dye-sensitized solar cells (DSSC) have been shown to have reached an interesting level of efficiency, while not having all the problems associated with the presence of a metal. Often these sensitizers have a \"donor-?-acceptor\" (D-?-A) architecture, where the acceptor groups is also involved in the interaction with titanium oxide[1]. In many cases, the acceptor/anchor group is a cyanoacrylate moiety but recently acceptors with different structural features, such as pyridine carboxylate, have been reported[2,3]. In this work, different dyes with a pyridine portion as acceptor group were synthesized and characterized, varying the position of the carboxyl group and the D-? group in the pyridine moiety. The isomers prepared showed significant differences both in absorption/emission spectra and in TiO2 up taking. Significantly insertion of appropriate substituents on the pyridine ring might be possible allowing to tune the optical properties of the dyes.
