Selective nickel/silver front metallization for graphene/silicon solar cells

In this work we studied front electrodes of nickel/silver (Ni/Ag) deposited on Gr/Si solar cell structure using field induced plating. These electrodes also be used as a front electrode on 2D graphene-based devices at very low cost and temperature (< 70 degrees C). Adhesion between the nickel and graphene was controlled by varying the solution temperature between 50 degrees C and 70 degrees C, followed by Ag plating at room temperature. It was observed that contact resistivity improved between plated electrodes and graphene, helpful in improving the F.F of the device from 49% to 60.1%. Efficiency was enhanced from 4.3% to 5.01%.
