Metal-organic frameworks derived carbon as a high-efficiency counter electrode for dye-sensitized solar cells

• MOF derived carbon materials were firstly applied as a counter electrode of DSCs.
• An efficiency of 7.32% can achieved which was comparable to that of Pt electrode.
• Calcination temperature influenced the properties of carbon counter-electrode.
• The residual ZnO influenced the electrical conductivity of carbon counter-electrode.

Metal-organic frameworks, ZIF-8, derived carbon materials are firstly applied as a counter electrode of dye-sensitized solar cells due to their easy fabrication, large specific surface area and high catalytic activities towards the reduction of I3− ions. An efficiency of 7.32% is achieved under the illumination of 1 sun (AM 1.5, 100 mW/cm2), which is comparable to that of the solar cell based on Pt electrode.
