1. A direct conversion sensor comprising:
a graphene;
a perovskite provided directly on the graphene surface;
a first electrode and a second electrode in electrical communication with the graphene; and
an encapsulant that encapsulates the first electrode and the second electrode, thereby electrically isolating said first electrode and said second electrode from the perovskite,
wherein the graphene is a continuous layer providing electrical communication between the first electrode and the second electrode; and
the graphene provides the only electrical connection to the perovskite.
