| Research Abstract |
In the present research, it has been tried to improve the performance of solar cells and field-effect transistors by using chemically exfoliated solubilized graphene as the constituent material of these devices. By adding solubilized graphene, photoconversion efficiency of the solution-processed thin film solar cell was improved to be higher than 12 %. It was also realized to obtain three times higher mobility of an organic thin film field-effect transistor by adding the solubilized graphene, and to fabricate a transparent transistor by using graphene transparent electrodes.
