Outline of Final Research Achievements

The nano-carbon materials should be new stages for the study of physics of photovoltaics, because the nano-carbon materials have novel electronic properties in comparison with those of conventional semiconductors. We studied the fabrication and investigation of optical properties in the nano-carbon materials (graphene quantum dots, and graphene oxides). The size separation of graphene quantum dots has been realized and the size dependent opt-electronic properties have been revealed. Moreover, we found that the graphene oxides fabricated show the similar opt-electronic properties in comparison with those of graphene quantum dots. We also carried out the studies of solar cell devices using nano-carbon materials.
