    Abstract: PURPOSE: A solar cell using graphene and a manufacturing method thereof are provided to easily manufacture a solar cell with a predetermined open circuit voltage by controlling the number of graphene unit layers. CONSTITUTION: A solar cell(100) comprises an anode electrode(110), a cathode electrode(140), a graphene layer(130), a semiconductor layer(120), and a photo reactive layer. The cathode electrode is arranged by being separated with the anode electrode. The graphene layer and the semiconductor layer are arranged between the anode electrode and the cathode electrode. The photo reactive layer generates electronics or a hole in response to entered light while being located in the interface of the semiconductor layer and the graphene layer. The graphene layer includes one or more graphene unit layers. The number of graphene unit layers, which constitutes the graphene layer, is controlled based on work function difference between the semiconductor layer and the graphene layer.
