ABSTRACT:
A plurality n of semiconductor elements U.sub.1 to U.sub.n are sequentially formed on a substrate side by side and connected in series. The element U.sub.i (where i=1, 2, . . . n) has a first electrode E.sub.i formed on the substrate, a non-single-crystal semiconductor laminate member Q.sub.i formed on the electrode E.sub.i and a second electrode F.sub.i formed on the laminate member Q.sub.i. The electrode F.sub.j+1 (J=1, 2 . . . (n-1)) is coupled with the electrode E.sub.j via a coupling portion K.sub.j formed by an extension of the electrode F.sub.j+1. The laminate member Q.sub.i has a N (or P) type first semiconductor layer, an I type second semiconductor layer and P (or N) type third semiconductor layer. The first E.sub.i has a first metal oxide layer which is formed of indium oxide or consisting principally thereof (or tin oxide or consisting principally thereof), depending upon whether the first semconductor layer is N or P type, respectively, and is contact with the first semiconductor layer. The electrode F.sub.i and the coupling portion K.sub.j have a second metal oxide layer which is formed of tin oxide or consisting principally thereof (or indium oxide or consisting principally thereof) depending upon whether the second semiconductor layer is P or N type, respectively, the second metal oxide layer being in contact with the third semiconductor layer and the coupling portion K.sub.j being coupled with first metal oxide layer of the electrode E.sub.j.
