Abstract
Abstract A plurality n of semiconductor elements U i to U n are sequentially formed on a substrate side by side and connected in series. The element U i (where i=1, 2, . . . n) has a first electrode E i formed on the substrate, a non-single-crystal semiconducotr laminate member Q i formed on the electrode E i and a second electrode F i formed on the laminate member Q i . The electrode F j+1 (j=1, 2, . . . (n-1)) is coupled with the electrode E j via a coupling portion K j formed by an extension of the electrode F j+1 . The laminate member Q i has an N (or P) type first semiconductor layer, an I type second semiconductor layer and P (or N) type third semiconductor layer. The second electrode F i and the coupling portion K j are formed by a layered member having a conductive metal oxide layer making contact with the non-single-crystal semiconductor laminate member Q i and a conductive material layer formed on the metal oxide layer where the second conductive material layer of the second electrode F i is a layer formed of chromium or a material consisting principally thereof.
