Efficiency enhancement for dye-sensitized solar cells with a porous NiO/Pt counter electrode

- A Pt-coated porous NiO nanosheet (PNO/Pt) film was studied as a counter electrode.
- The electrocatalytic activity of the DSSC is enhanced by using the PNO/Pt structure.
- The PNO/Pt CE shows 13% improvement in the solar efficiency over the Pt CE.
