Photoconductor on active pixel image sensor

A camera with a MOS or CMOS based active sensor array for producing electronic images from charge producing light, said camera comprising:

• A) a crystalline substrate,
• B) a charge generating photoconducting layer comprised of at lease two layers of charge generating material for converting the light into electrical charges,
• C) a plurality of MOS or CMOS pixel circuits fabricated in said substrate below said charge generating layer, each pixel circuit comprising a charge collecting electrode, a capacitor and at least three transistors, said pixel circuits being arranged to collect and read out charges generated in said charge generating layers,
• D) a surface electrode in the form of a thin transparent layer or grid located above said layer of charge generating material,
• E) an electrical source for providing a reverse bias across said charge generating photoconducting layer,
• F) additional MOS or CMOS circuits in and/or on the same crystalline substrate with said active sensor array for converting the charges into images,
• G) additional MOS or CMOS circuits in and/or on the same crystalline substrate with said active sensor array for timing and signal synchronization, and
• H) focusing optics for focusing electron-hole producing light onto said active sensor array.
