METHOD FOR PREPARING GRAPHENE, TRANSPARENT ELECTRODE INCLUDING SAME, ACTIVE LAYER, AND DISPLAY DEVICE, ELECTRONIC DEVICE, PHOTOVOLTAIC DEVICE, BATTERY, SOLAR CELL, AND DYE-SENSITIZED SOLAR CELL WHICH EMPLOY SAME

Document Type and Number:

WIPO Patent Application WO/2012/102574

Kind Code:

A2

Abstract:

The present invention relates to a method for preparing graphene, transparent electrode including the same, an active layer, and a display device, an electronic device, a photovoltaic device, a battery, a solar cell, and a dye-sensitized solar cell which employ the same. The method for preparing graphene comprises the following steps of: (a) preparing a target substrate and a metal foil; (b) increasing the size of metal foil grains by heat-treating the metal foil; (c) supplying the metal foil in which the size of the grains is increased to the target substrate; (d) supplying carbon fuel on the metal foil; (d) heating the supplied carbon fuel, the target substrate, and the metal foil; (e) diffusing carbon atoms generated through the pyrolysis of the heated carbon fuel into the metal foil; and (f) forming graphene on the target substrate by carbon atoms diffused into the metal foil.
