This is a Ph.D. dissertation. Life on earth is powered by the sun. Green plants and many bacteria use sunlight to provide their energy needs. Moreover, while it is the earth's only inexhaustible energy source, solar light forms the most important source of sustainable energy.

As the energy needs of the earth are likely to double in the next 50 years, while the fossil fuel reserves will only last for another 200 years, the stage is set for a major energy shortage unless renewable energy sources can cover this deficit. The annual solar radiation received by the earth amounts to 3x1024 J, 5% of which is UV, 43% visible and 52% IR light. This number exceeds the present world energy consumption by several thousand times.

Contents include: Introduction, Materials and methods, Contactless determination of the efficiency of photo-induced charge separation in a porphyrin-TiO2 bilayer, Photo-induced charge separation in Ti02/Porphyrin bilayers studied by time-resolved microwave conductivity, Efficient charge separation in a smooth-Ti02/Palladium-porphyrin bilayer via long-distance triplet state diffusion, Singlet and triplet exciton diffusion in a self-organizing porphyrin antenna layer, Electrodeless determination of the trap density, decay kinetics and charge separation efficiency of dye-sensitized nanocrystalline Ti02, Contactless determination of the photoconductivity action spectrum exciton diffusion length and charge separation efficiency in polythiophene-sensitized Ti02 bilayers, Triplet exciton diffusion and delayed interfacial charge separation in a Ti0s/PdTPPC bilayer: Monte Carlo simulations, The application of a low-bandgap conjugated oligomer for the sensitization of Sn02 and Ti02.
