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.

在目前的研究中，已经尝试通过使用化学剥离的增溶石墨烯作为这些器件的构成材料来提高太阳能电池和场效应晶体管的性能。通过添加增溶石墨烯，溶液加工的薄膜太阳能电池的光转换效率提高到高于12%。还实现了通过添加增溶石墨烯使有机薄膜场效应晶体管获得三倍高的迁移率，并通过使用石墨烯透明电极制造透明晶体管。
