GRAPHENE SHEET, TRANSPARENT ELECTRODE INCLUDING GRAPHENE SHEET, ACTIVE LAYER, AND DISPLAY DEVICE, ELECTRONIC DEVICE, PHOTOVOLTAIC DEVICE, BATTERY, SOLAR CELL, AND DYE-SENSITIZED SOLAR CELL EMPLOYING TRANSPARENT ELECTRODE

摘要

The present invention relates to a graphene sheet, a transparent electrode including the graphene sheet, an active layer, and a display device, an electronic device, a photovoltaic device, a battery, a solar cell, and a dye-sensitized solar cell employing the transparent electrode. The graphene sheet comprises: a lower sheet including 1-20 layers of graphene; and a ridge which is formed on the lower sheet and includes more layers of graphene than the lower sheet, wherein the ridge is in the grain boundary form of a metal.
