We report that B-doped graphene (BG) is prepared and tested as a counter electrode (CE) in dye-sensitized solar cells (DSSCs) in conjunction with Co(bpy)32+/3+ redox couple. The BG CE has a lower charge-transfer resistance and much higher electrochemical stability than those of Pt CE. As a result, the DSSC fabricated with BG CE exhibits superior power conversion efficiency to that of DSSC with Pt CE, suggesting potential to replace expensive Pt CE in DSSCs.
