“…The difference between the observed photoresponses for CV and BG, two structurally related triaryl methane dyes, is presently not clear. Both have similar standard potentials for the first oxidation process of the triaryl methane unit (31) and identical net charge at neutral pH. The ethyl groups on BG may promote less efficient packing when adsorbed onto GaP.…”

Single crystalline, non-degenerately doped p-type gallium phosphide (GaP) electrodes were examined for the purpose of constructing aqueous-based dye-sensitized systems featuring light-stimulated hole injection. Features including the relevant semiconductor-sensitizer energetics, surface conditioning, and redox mediator are examined to define system aspects that most strongly affect internal quantum yields for charge injection. The present findings indicate that the preparation of GaP electrode interfaces strongly influences charge injection yields.
