We report a novel preparation method for a graphene/TiO 2 nanohybrid using a supramolecular biomaterial (CDT1). CDT1 can offer an increase in the dispersibility of graphene in water and subsequent complexation of graphene and TiO 2 . This nanohybrid was applied to a perovskite solar cell and success...

Summary:We report a novel preparation method for a graphene/TiO 2 nanohybrid using a supramolecular biomaterial (CDT1). CDT1 can offer an increase in the dispersibility of graphene in water and subsequent complexation of graphene and TiO 2 . This nanohybrid was applied to a perovskite solar cell and success was achieved in improving its photoelectric conversion efficiency. An easy and green preparation method for a graphene-TiO 2 nanohybrid by using a biomaterial is proposed, and the nanohybrid can be applied to perovskite solar cells.
