Abstract
Abstract A photoelectric converting device has non-monocrystalline semiconductor layers of PIN structure laminated on mutually isolated plural pixel electrodes. P- or N-doped layer on the pixel electrode contains at least a microcrystalline structure. N- or P-doped layer on the area other than the pixel electrode is amorphous.
