METHOD OF PREPARING GRAPHENE DEPOSITED COUNTER ELECTRODES BY ELECTRO-PHORETIC DEPOSITION, COUNTER ELECTRODES PREPARED BY THE METHOD AND DYE-SENSITIZED SOLAR CELL COMPRISING THE ELECTRODES

摘要

PURPOSE: A method for manufacturing an opposite electrode by depositing graphene with an electrophoresis method, the opposite electrode made by the same, and a dye sensitized solar cell including the opposite electrode are provided to improve current density. CONSTITUTION: Graphene mixture solutions are made by adding graphene to dispersed solutions. The graphene is stacked by inputting a transparent electrode to the mixture solutions and applying a voltage for 5 seconds to 5 minutes. The graphene is thermally processed at 350 to 600 degrees centigrade at a nitrogen atmosphere. The content of the graphene is 0.25w% in the mixture solutions. The voltage is 10 to 30 V in a graphene deposition process. The dispersed solutions are made of alcohol and magnesium nitrate.
