Patent ID: 7875841

Claim:
A pixeled flat detector having rows and columns of pixels arranged in a pixel array, each comprise at least one organic photodiode, a reset transistor, an amplifying transistor and a read transistor, wherein the organic photodiode comprises: a pixel anode formed from material selected from the group consisting of Au, Pd, Pt, and ITO; an organic semiconductor layer formed from a blend of (a) an organic electron transport component selected from the group consisting of C60 and PCBM and (b) an organic hole transport component selected from the group consisting of P3HT and PPV; and a semitransparent cathode formed from material selected from the group consisting of Ba, Ca, Mg, LiF and CsF; wherein the organic photodiode is connected to a supply a voltage V 1 which is common to all pixels; wherein the organic semiconductor layer and the semitransparent cathode extend continuously over the entire pixel array in an unstructured fashion; and wherein the pixel anode overlaps the reset transistor and the amplifying transistor, but does not substantially overlap the read transistor.
