  • Photosensor array wherein each photosensor comprises a plurality of amorphous silicon p-i-n diodes
    Patent number: 4482804
    Abstract: In a photosensor apparatus of the type including one dimensional photosensor array in which a plurality of photosensors mounted on a transparent substrate at a predetermined spacing are respectively connected in series with blocking diodes which select outputs of the photosensors. Each one of the photosensors comprises a plurality of laminated amorphous silicon diodes comprising p-i-n junction layers. Each blocking diode comprises at least one amorphous silicon diode having a p-i-n junction layer, and each photosensor generates an electromotive force larger than a forward voltage drop across each blocking diode.
