Abstract

A transparent second electrode layer laminated over a laminated composite of a solar cell structure is connected to a third electrode layer disposed opposite the substrate via through holes spaced longitudinally and equidistantly apart from each other. The laminated composite and the third electrode layer are respectively segmented by separating grooves into regions involving through holes of a number inversely proportional to that of the series-connected solar cell units. A first electrode layer is connected to the third electrode layer via the through holes of the substrate or via conductors passing over the side thereof in the adjoining region across the separating grooves. The through holes for connected in the first electrode layer with the third electrode layer and the through holes for connecting the second electrode layer with the third electrode layer are formed and arranged equidistantly apart from each other, and the latter though holes which are not needed are removed.
