Photoelectric conversion device

Claim 1

A photoelectric conversion device comprising: a substrate having an insulating surface; and a plurality n (n being an integer larger than one) of semiconductor elements U 1 to U n sequentially formed thereon side by side and connected in series one after another; wherein the semiconductor element U i (i=1, 2, . . . n) has a first electrode E i formed on the substrate, a non-single-crystal semiconductor laminate member Q i formed on the first electode E i and having formed therein at least one semiconductor junction, and a second electrode F i formed on the non-single-crystal semiconductor laminate member Q i in opposing relation to the first electrode E i ; wherein the second electrode F j+1 (j=1, 2, . . . (n-1)) of the semiconductor element U j+1 is coupled with the first electrode E j of the semicondutor element U j through a coupling portion K j formed by an extension of the second electrode F j+1 ; wherein the first electroes E j and E j+1 are separated by a first groove G j ; wherein the second electrode F j+1 extends on the non-single-crystal semiconductor laminate member Q i in opposing relation to the first electrode E i ; wherein the second electrodes F j and F j+1 are separated by an isolating portion H j in the non-single-crystal semiconductor laminate member Q i ; wherein a second groove O j is cut in the non-single-crystal semiconductor laminate member Q i between the second electrode F j+1 and the first electrode E j to extend into the latter; and wherein the coupling portion K j extends into the second groove O j to be coupled with the side of the first electrode E j exposed to the second groove O j .
