Scheme 1.

Operation mechanism of the dye sensitized electrochemical solar cell (DSSC). S: Dye sensitizer, S*: Electronically excited dye sensitizer, S+: oxidized dye sensitizer O/R: redox couple (e,g, I3/I). CB: Conduction band for semiconductors, VB: valence band for semiconductors. (A) Wet-type DSSC with redox couple in the liquid electrolyte. (B) Solid state DSSC with a p-type semiconductor to replace the electrolyte containing the redox couple.
