Semiconductor coated microporous graphene scaffolds for solar cells

ISBN Number:



The invention refers to a high surface area scaffold to be used for a solar cell, made of a three-dimensional percolated network of functionalized graphene sheets. It may be used in the prepn. of a high surface area electrode by coating with a semiconductive material. Electronic devices can be made therefrom, including solar cells such as dye-sensitized solar cells. [on SciFinder(R)]
