Graphene Quantum Dots Open Up New Prospects for Interfacial Modifying in Graphene/Silicon Schottky Barrier Solar Cell

(a) Schematic illustration of the solar cell fabrication process. (b) Cross-sectional image shows both the electrons and holes are ripped out of the photo-generated electron-hole pairs at the interface under the driving force from the built-in electric field; then, the electrons invest in the silicon substrate while the electric field gives the holes access to the graphene electrode so that the device gets credit for converting from light energy to electric energy. (c) Schematic illustration of MIS Schottky junction solar cells with GOQD interlayer barrier.
