Photoelectrochemistry of composite semiconductor thin films. Photosensitization of the SnO2/TiO2 coupled system with a ruthenium polypyridyl complex
Article Abstract:
A study was conducted to analyze the photoelectrochemistry of composite semiconductor thin films and the suppression of charge recombination in nanoporous dye sensitized photoelectrochemical solar cells. A TiO2 colloidal solution underwent spin coating to prepare the electrodes. Experimental results indicated that coupled semiconductor electrodes can generate an efficient charge separation in nanoporous dye sensitized photoelectrochemical solar cells.

Controlling dye (merocyanine-540) aggregation on nanostructured TiO2 films. An organized assembly approach for enhancing the efficiency of photosensitization
Article Abstract:
A study was conducted to analyze anionic dye Merocyanine 540 aggregation on nanostructured TiO2 films. The benefits of integrating dyes in organized assemblies for suppressing nonradiative decay of the excited-state sensitizer and reducing the aggregation effects on semiconductor surfaces were discussed. Results indicated that H-aggregates of the merocyanine dye are less efficient than its monomer counterpart in sensitizing titanium dioxide.
