▎ 摘　　要

NOVELTY - The junction has a silicon dioxide layer (2) whose middle part is provided with a vent, and an annular golden membrane (1) placed on the silicon dioxide layer. An inner hole of the golden membrane, the vent of the silicon dioxide layer and a surface of an N-type mono-crystal silicon chip (3) form in a stage hole. An end of the titanium-palladium-silver back electrode (4) is provided with a conductive wire. A graphene membrane (5) is formed on a surface of the stage hole. An end of the graphene membrane is provided with another conductive wire. USE - Graphene/silicon Schottky junction. ADVANTAGE - The junction provides a photovoltaic cell which lowers the utilization of silicon. The junction is easy to assemble, inexpensive and is suitable for large-scale production. DESCRIPTION OF DRAWING(S) - The drawing shows top and front views of a graphene/silicon Schottky junction.
