Modeling dye-sensitized solar cells with graphene based on nanocomposites in the Brillouin zone and density functional theory

Abstract

Graphene-based nanocomposites are usable as flexible transparent displays for electronic devices. However, the power conversions of graphene-based nanocomposites are more efficient than that of indium tin oxide. This outlook property can alternative for graphene-based materials in solar cells. The strength of graphene is due its ability to enable various components in existing solar cells, leading to the overall improvement in power conversion efficiency. Graphene can act as an electron acceptor and intermediate layer in tandem solar cells. Depending on the properties of graphene and graphene-based material, researchers have modified the structure where the π-electron variety, donor–acceptor and conformation can be tuned to create a novel type of light-reaping materials.
