Photosensitization Aspects of Pinacyanol H-Aggregates.Charge Injection from Singlet and Triplet Excited States into SnO_2 Nanocrystallites.

摘要

Dye aggregates are useful in developing light-harvesting arrays for artificial photosynthetic systems.Use of such dye aggregates as light harvesting antennas as well as photosensitizers in photoelectrochemical cells have been demonstrated recently Basic understanding of the dye aggregation on nanoparticle surface as well as the excited state interaction with the semiconductor support is important in developing efficient photoelectrochemical solar cells.
