<p>An x-ray image sensor (1) with a lead-oxide photoconductor layer (6) positioned between collecting electrodes (3) and a common electrode (2) is provided with a passivation layer (7) which separates the lead-oxide from the metal of the common electrode to counteract degradation of the photoconductor layer due to chemical reactions between the metal of the common electrode and the lead-oxide. A bias layer (8) is provided between the common electrode (2) and the photoconductor layer (6) and a cladding layer (9) is provided between collecting electrodes (3) and the photoconductor layer (6) so as to avoid injection of charges into the photoconductor layer.</p> |
