EFFECTS OF DIFFRENT GRAPHENE SHEETS AND QUANTUM DOTS ON PHOTOELECTRICAL PORPERTIES OF ORGANIC PHOTOVOLTAIC CELLS

摘要：

Graphene has been extensively investigated for many applications due to its two-dimensional structure and unique physical properties, such as high intrinsic carrier mobility, excellent mechanical strength, and superior thermal conductivity, which may play a major role in developing new type of organic photovoltaic (OPV) devices. In this research, we utilized hydrothermal method to successfully synthesize graphene sheets, nitrogen (N)-doped graphene sheets, and boron (B)-doped graphene sheets, and used electrical deposition method to form quantum dots on the graphene surface. Our experimental results demonstrate that, the introduction of N and B can effectively change electronic properties of graphene sheets and thereby alter their interactions with quantum dots (Ag2S, Ag2Se, ZnS, and ZnSe) for their photoelectrical properties.
