Stable 16.2% Efficient Surface Plasmon-Enhanced Graphene/GaAs Heterostructure Solar Cell

By simply spinning Au nanoparticles on the surface of graphene/GaAs heterojunction, a stable solar cell with a power conversion efficiency (PCE) of 16.2% is achieved. The surface plasmon resonance of Au nanoparticles enhances the electromagnetic field near the graphene/GaAs junction area, which sign...

Zusammenfassung:By simply spinning Au nanoparticles on the surface of graphene/GaAs heterojunction, a stable solar cell with a power conversion efficiency (PCE) of 16.2% is achieved. The surface plasmon resonance of Au nanoparticles enhances the electromagnetic field near the graphene/GaAs junction area, which significantly improves the short current value and PCE.
