NOVELTY - Solar cells are serially interconnected by forming isolation scribes that remove the front contact layer in selected areas; forming electrical interconnections that connect the top contact proximate one subcell to the back contact proximate the neighboring subcell where the connections are at the back contact formed through the via scribes; and forming substrate isolation scribes to electrically connect neighboring subcells in series where the substrate isolation scribe are being formed on the side of the substrate not coated with the thin-film layers.    USE - Method for series interconnection of solar cells.    ADVANTAGE - The method reduces or eliminates product loss due to handling of individual pieces during series interconnection thus improving product yield.    DETAILED DESCRIPTION - Solar cells are serially interconnected by:    (A) forming a complete thin-film semiconductor solar cell comprising a semiconductor layer and a front contact layer directly on a conducting substrate;    (B) forming via scribes that remove the semiconductor layer and all layers above in selected areas;    (C) forming isolation scribes that remove the front contact layer in selected areas;    (D) applying insulating barrier materials to selected portions of the via scribes;    (E) forming electrical interconnections that connect the top contact proximate one subcell to the back contact proximate the neighboring subcell where the connections are at the back contact which are being formed through the via scribes;    (F) laminating an insulating, transparent and protective encapsulant to the front of the solar cell; and    (G) forming substrate isolation scribes to electrically connect neighboring subcells in series where the substrate isolation scribe are being formed on the side of the substrate not coated with the thin-film layers.
