The demand for alternative power sources has drawn the attention to a variety of light harvesting devices. Among these, the dye sensitized solar cells (DSSCxs) have attracted a number of research groups in the last decades. Here we present a series of organic chromophores based on a by us published dye, D5. To extend the spectral response of the D5 chromophore compared to N719 and to fine tune the HOMO and LUMO energy levels of the sensitizers on a molecular level, a number of modifications can be made. The chromophores consist of donor, linker and acceptor groups, which can be alternated independently to tune the HOMO and LUMO energy level contributions of different groups and to attain a HOMO and LUMO energy library.
