Patent ID: 6995445

Claim:
An organic position sensitive detector comprising: a first electrode, wherein the first electrode is resistive and has a first point and a second point; a first contact in electrical contact with the first point on the first electrode; a second contact in electrical contact with the second point on the first electrode; a second electrode disposed near the first electrode; a donor semiconductive organic layer disposed between the first electrode and the second electrode; and an acceptor semiconductive organic layer disposed between the first electrode and the second electrode and adjacent to the donor semiconductive organic layer, wherein a hetero-junction is located between the donor layer and the acceptor layer, and at least one of the donor layer and the acceptor layer is light absorbing; and wherein the detector further comprises at least one of a third contact, located at a third point on the resistive electrode; and a third electrode, wherein the third electrode is resistive and has a first point and a second point; a third contact in electrical contact with the first point on the third electrode; and a fourth contact in electrical contact with the second point on the third electrode, and wherein the third electrode is disposed near the first electrode.
