Synergistic Nanostructured Electrochemically Reduced Graphene Oxide/Molybdenum Trioxide Photoelectrodes For Enhanced Photoresponse

Öz

Photovoltaic systems that convert solar energy into electrical energy are one of the promising solutions for clean and renewable energy resources to meet the rapidly increasing energy need in the world. For this purpose, investigation of new photovoltaics with high conversion efficiency has gained importance for alternative strategies. Goal of this research is to present electrochemical synthesis and photoresponse of synergistic nanostructured electrochemically reduced graphene oxide/molybdenum trioxide photoelectrodes for proposing an alternative photovoltaic material. With this work, the obtained results indicate that electrochemically synthesized photoelectrodes are utilizable as new alternative materials for various energy production devices, such as solar cells. These interpretations can later be verified by subsequent solar cell applications.
