• titanium dioxide serves to accept photoinduced electrons from sensitizers that cannot be strictly considered as SAMs, i.e., most types of dye-sensitized solar cells (DSSCs). Review Self-assembled monolayers chemisorbed on TiO2 Both TiO2 and SiO2 are oxides capable of forming surface hydroxyls, and

• studied quite thoroughly for both organothiolated SAMs on metals and organosilanes on silicon. The appearance of dye-sensitized solar cells [85], based on (disordered) dye molecules attached to the surface of nanoparticulate titanium dioxide, provoked interest also in the charge transport from SAMs to

• . A claim was made that similar paths yielding long-lived charge separation situations may be relevant also in natural photosynthetic systems, and should be considered in the development of dye-sensitized solar cells. In certain cases, feasibility studies with TiO2-containing systems were later

The picosecond-resolved, time-correlated single

Conclusion Dye-sensitized solar cells with a ZnO/Au nanocomposite as the photoelectrode were
