Dye Sensitized Solar Cells (DSSCs) usually involve one dye with a small absorbance range. Forster resonance energy transfer (FRET) allows for an increased absorbance range with the use of dye pairs. In the work described here, two pairs of dyes where characterized and incorporated into DSSCs. The dye pairs were fluorescein with coumarin and rhodamine b with fluorescein. It was seen that the pairs have a strong FRET relationship. The absorbance and fluorescence were characterized individually for each dye and in FRET pairs for different concentrations. The dyes were then tested in solar cells to examine how the FRET characteristics affect efficiency. Additionally, solvent effects on FRET were also examined. Through characterization of dye pairs and their integration into solar cells, it can be demonstrated that FRET affects the operating efficiency of DSSCs.
