Two kinds of graphene-based composites for photoanode applying in dye-sensitized solar cell

▸ A novel photoanode with three-layer structure is prepared for DSSCs. ▸ The η reaches 8.67% when the prepared photoanode is adopted. ▸ Scattering and transport layers obviously increase the Jsc and Voc. ▸ The detailed characterizations of the adding layers are performed.
