Electron photogeneration

Fig. 14. Time evolution of the peak position E of the absorption band of the electron photogenerated in four polyols O propane-1, 3-triol, O ethane-1,2-diol, propane-1,3-diol and A propane-1,2-diol [Reprinted from Ref. 106, Copyright 2008, with permission from American Chemical Society].

Generation = absorption In the case of bipyridal Ru dyes, electron injection from excited dye molecules occurs in subpicosecond time scales with unit efficiency [82, 90, 91], Therefore light absorption by the dye can be considered equivalent to electron photogeneration.
