Since the first report concerning dye-sensitized solar cells (DSSCs), a power conversion efficiency of 14.3% has been achieved in a co-sensitized solar cell featuring a cobalt (II/III) complex redox electrolyte solution and graphene nanoplates as a counter electrode. However, the potential problems caused by the liquid electrolytes, such as the leakage and volatilization of liquid, are considered as some of the critical reasons limiting the long-term performance and practicable use of DSSCs. In this study, solid-state DSSCs with both dopants and a organic triphenylamine derivative as a hole transporting material were fabricated, and effects of the dopants on the photovoltaic performance were investigated. |
