Graphene quantum dots sensitized C-ZnO nanotaper photoanodes for solar cells application

In a paper to be published in the forthcoming issue in NANO, researchers from the National Institute of Technology, India, have synthesized blue-green-orange photoemissive sulfur and nitrogen co-doped graphene quantum dots (SNGQDs) using hydrothermal method. These GQDs showed strong UV-visible photoabsorption and excitation dependent photoemission which have low-cost, eco-friendly solar cell application.
