| Outline of Final Research Achievements |
In this study, we developed a novel technique to improve the surface band structure and to control the nanosurface and interface structure of semiconductor oxide nanoparticles by codope processing of the cation and the anion using the sol-gel method that was a chemical treatment method and the low-temperature plasma treatment method and the ion-implantation that were a physical treatment method. By the developed technique, we clarified the effects of the surface and interface nanostructure and surface band structure of the inorganic matter (semiconductor oxide nanoparticles) in the (inorganic/organic) composite material on the electronic movement and diffusion between the semiconductor oxide electrodes and organic molecules (dyes). Also, we examined to optimize the surface band structure to improve a photoelectric conversion characteristic of the cells. It was tried to examine the high efficiency of the dye -sensitized solar cells by the optimized combined treatment.
