Graphene sheet, transparent electrode, active layer including the same, display, electronic device, optoelectronic device, battery, solar cell, and dye-sensitized solar cell including the electrode or active layer

摘要

The present invention relates to a graphene sheet and a transparent electrode, and an active layer including the same, and a display device, an electronic device, an optoelectronic device, a battery, a solar cell, and a dye-sensitized solar cell including these. The graphene sheet includes a lower sheet including 1 to 20 graphene layers, and a ridge formed on the lower sheet and including more graphene layers. The ridge has a metal grain boundary shape.
