Graphene-enhanced three-dimensional structures of MoS2 nanosheets as a counter electrode for Pt-free efficient dye-sensitized solar cells

MoS2 nanoflakes self-assemble on the graphene aerogel as a synthetic template at random and then the hybrids (MG) was used as an alternative platinum counter electrode in dye-sensitized solar cells with higher power conversion efficiency (7.86%).317
