Photosensitive material, charge separation

In this chapter we emphasize the use of homogeneous photosensitizers as light-harvesting components in artificial photosynthetic systems. Other reviews and monographs highlight the application of semiconductor materials in photosynthetic devices [48-50]. Nevertheless, several aspects of ET and charge separation are common to homogeneous photosensitizers and semiconductor photoactive materials, and these interrelations will be mentioned in later sections.
