Molecular Switches: Optoelectronic components based on a dye-sensitized TiO2 solar cell

Electronic components must continue to get smaller: Miniaturization has now reached the nanometer scale (10^-9 m). In this tiny world, classic semiconductor technology is reaching its limits. We now need switches and other devices whose dimensions are on the scale of individual molecules. The difficulty with this is in the addressability and compatibility of molecular systems with the available nanoelectronic components. Until now, all molecular systems require at least one step in which a solution must be injected into the system and then rinsed out again, which is time-consuming.
