Photo-induced Charge Separation across the Graphene–TiO Interface Is Faster than Energy Losses: A Time-Domain ab Initio Analysis.

Graphene-TiO composites exhibit excellent potential for photovoltaic applications, provided that efficient photoinduced charge separation can be achieved at the interface. Once charges are separated, TiO acts as an electron carrier, while graphene is an excellent hole conductor. However, charge sepa...
