Enhanced photovoltages in twisted‐bilayer graphene are obtained by adjusting twist angle and surface plasmon resonance. Results show that our metal–graphene–metal photodetector has incident‐angle‐dependent and polarization‐dependent properties. The photovoltage intensities are related to the number of graphene layers and the twist angle. Twisted‐bilayer graphene at the optimal incidence angle has an ≈700% enhanced photovoltage.
