▎ 摘  要

NOVELTY - The high surface area scaffold comprises a three-dimensional percolated network of functionalized graphene sheets. The percolated functionalized graphene sheets have surface areas of 300-2630 m/g, and are present in the form of graphene tapes. The functionalized graphene sheets comprise a combination of single sheet graphene and stacks of 2 or more graphene sheets. The three-dimensional network of functionalized graphene sheets is optically semi-transparent and has a thickness of 0.01-100 mu m. The scaffold is coated with a semiconductive material having a thickness of 50-150 nm. USE - The high surface area scaffold is useful in an electrode of a dye-sensitized solar cell and an electronic device (all claimed). ADVANTAGE - The high surface area scaffold increases the efficiency, reliability and modularity of solar cells, reduces the electron recombination effect, and exhibits mechanical and electrical properties thus allowing them to carry large currents and reach high temperatures without adverse effects. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method of coating the conducting scaffold.
