Synthesis and characterization of carbazole-based donor organic dyes for dye sensitized solar cells

This thesis deals with synthesis and characterization of carbazole-based donor organic dyes. The designed D-pi-A organic dyes containing different linker and acceptor units and designed D-D-pi-A organic dyes containing different linker units for using as dye molecules in dye-sensitized solar cell. The target molecules were characterized by 1H-NMR 13C-NMR and FT-IR. The target molecules exhibit a adsorption band cover UV and visible region. All compounds show good thermal properties. The photovoltage performance of DSCs using these materials as dyes is under investigation and will be reported in the future.
