A method of making a series connected array of amorphous silicon solar cells on a single substrate includes forming a plurality of spaced conductive lower electrodes on the substrate. Metal electrode stripes are applied on each of the lower electrodes. A layer of amorphous silicon is formed over the lower electrodes, metal electrode stripes and any exposed portions of the surface of the substrate. A plurality of spaced upper conductive electrodes are formed over the amorphous silicon layer with each of the upper electrodes having a portion overlying the electrode stripe on the lower electrode of an adjacent cell. The array is heated to spike the electrode stripes completely through the amorphous silicon layer to contact the overlying upper electrode and thereby electrically connect the cells in series.
