摘要

Elucidating the properties of the interface between traditional inorganic solid-state conductors and novel organic charge carriers is among the biggest challenges of the rapidly developing field of molecular optoelectronics. In many cases, the organic-inorganic contacts determine the overall efficiency of a molecular device and create key bottlenecks for conductivity and charge transfer. The highly dispersed titanium dioxide sensitized with organic chromophores used in solar cells provides an excellent example of an organic-inorganic contact. The system is currently under extensive investigation by a variety of experimental techniques that supply valuable input for detailed theoretical modeling.
