  • a monomolecular layer of a suitable transition metal complex placed on the rough surface of the titanium dioxide layer acts as a sensitizer in such a way that, after excitation by visible light, it injects electrons into the conduction band of the titanium dioxide. With this system it is possible to convert over 80% of the incident photons into electrical current in the wavelength range of the absorption maximum of the sensitizer.
  • the electrons pass through the adjoining current-conducting coating into an external circuit, where they do work, and back to the cell into the current-conducting coating of the other glass pane.
