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