ABSTRACT:
A semiconductor photoelectric conversion device has a conductive substrate or a first conductive layer formed on a suitable substrate, a non-single-crystal semiconductor laminate member formed on the conductive substrate or first conductive layer, including at least one I-type non-single-crystal semiconductor layer and having formed therein at least one PI, NI, PIN or NIP junction, and a second conductive layer formed on the non-single-crystal semiconductor laminate member. The I-type non-single-crystal semiconductor layer of the non-single-crystal semiconductor laminate member contains oxygen, carbon or phosphorus only in such a low concentration as 5.times.10.sup.18 atoms/cm.sup.3 or less, 4.times.10.sup.18 atoms/cm.sup.3 or less, or 5.times.10.sup.15 atoms/cm.sup.3 or less, respectively.
