THE INVENTION PERTAINS TO A METHOD FOR MAKING A SOLAR CELL MODULE COMPRISING SOLAR CELLS CONNECTED IN SERIES, COMPRISING THE STEPS OF: A) MAKING IN A SYSTEM COMPOSED OF A SUBSTRATE (1)-OVERLAID BY A FIRST ELECTRODE LAYER, ITSELF OVERLAID BY AN ACTIVE LAYER (3), A FIRST, INTERRUPTIONS GROOVE PROVIDING AN INTERRUPT IN THE FRONT ELECTRODE AND THE ACTIVE LAYER (3) AND A SECOND, INTERCONNECTION, GROOVE THROUGH THE ACTIVE LAYER (3), THE FIRST AND SECOND GROOVES BEING POSITIONED CLOSE TO EACH OTHER; B) INSERTING AN INSULATING COMPOUND (6) INTO THE INTERRUPTION GROOVE; C) APPLYING A LIFT-OFF COMPOUND (7) ONTO THE ACTIVE LAYER (3) AT A POSITION ADJACENT TO THE INTERCONNECTION GROOVE ON THE OTHER SIDE OF THE INTERCONNECTION GROOVE THAN THE INSULATION GROOVE; D) APPLYING THE SECOND ELECTRODE; E) REMOVING THE LIFT-OFF COMPOUND (7) AND THE OVERLAYING SECOND ELECTRODE AT THAT POSITION TO OBTAIN A GROOVE IN THE SECOND ELECTRODE.
