Graphene and Graphene/TiO2 Nanocomposites for Renewable Dye Sensitized Solar Cells


Graphene and Graphene/TiO2 Nanocomposites for Renewable Dye Sensitized Solar Cells

Foo Wah Low, Chin Wei Lai, Christelle Pau Ping Wong

Renewable solar cell energy is a key target for sustainable energies development, which are inexhaustible and non-polluting for our energy system. To bring more solar related technologies to the point of commercial readiness and viability in terms of performance and cost, substantial research on the development of high efficient renewable dye-sensitized solar cell (DSSCs) device is necessary. Recent studies have indicated that graphene is a relatively novel material with unique properties that could apply in photoanode/counter electrode component as efficient electrode. In fact, the atom-thick 2D structure of graphene (rGO) provides an extraordinarily high conductivity, repeatability, productivity, and prolong lifetime to the related solar cell applications. Continuous efforts have been exerted to further improve the graphene textural and electronic properties by loading an optimum content of titanium dioxide (TiO2) as an efficient photocatalyst in DSSCs. In this chapter, different synthesis strategies and characterization analyses for TiO2-rGO nanocomposites (NC) as well as its prospects in DSSCs will be reviewed in detail.
