Abstract
A solar cell comprises a plurality of series connected photoelectric conversion structures formed on a substrate. The conversion structure consists of a first semiconductor film on a P-type, an intrinsic semiconductor film formed on the first semiconductor film such that one end thereof extends beyond an end of the first semiconductor film and a second semiconductor film of a second, opposite conductivity type formed on the intrinsic semiconductor film such that one end thereof extends beyond the extended end of the intrinsic semiconductor film and makes direct electrical contact with an end of the first semiconductor film of the adjacent structure.
