Abstract

We report a novel preparation method for a graphene/TiO₂ nanohybrid using a supramolecular biomaterial (CDT1). CDT1 can offer an increase in the dispersibility of graphene in water and subsequent complexation of graphene and TiO₂. This nanohybrid was applied to a perovskite solar cell and success was achieved in improving its photoelectric conversion efficiency.
