Large area array of thin film photosensitive elements for image detection

摘要

Apparatus for producing electronic signals which are representative of a detectable condition on an image-bearing surface. The apparatus includes an elongated array of distinct thin film photosensitive elements formed on a common flexible large area substrate. The elongated array of photosensitive elements are fabricated as a large area, photovoltaic structure formed of a plurality of thin film layers, including a first layer of thin film conductive material. The discrete photosensitive elements are defined by patterning of the conductive layer into shaped regions which determine the overall configuration and dimensions of each element.
