Recent studies have indicated that graphene is a relatively novel material with unique properties that
could apply in solar-based application, such as quantum dot solar cells (QDSSCs), dye-sensitized solar cells
(DSSCs), and perovskite solar cell (MSSCs). Graphene film is considered to be an ideal two-dimensional catalytic
support due to its excellent electrical and thermal conductivity, mechanical strength, large surface area and incredibly
high mobility of charge carriers. Lately, continuous efforts have been exerted to further improve the graphene
textural and electronic properties by loading an optimum content of TiO2 for high efficiency solar-based application.
In this review paper, an introduction of graphene / TiO2-graphene film, mechanism of formation, synthesis
method, and potential solar applications are reviewed in details.
