STABILIZED SHINGLED SOLAR CELL STRINGS AND METHODS FOR THEIR PRODUCTION

The present invention is directed to solar cell strings comprising (i) a string of solar cells shingled in string direction, resulting in positive and negative electrode overlap, (ii) an interconnect for electrically connecting the positive and negative electrodes of the shingled solar cells, and (iii) an adhesive foil spanning at least part of the string and positioned on (a) the top (sun facing) sides of the at least two shingled solar cells, and/or (b) the bottom (far) sides of the at least two shingled solar cells, or on (c) the top side of one solar cell and on the bottom side of the overlapping solar cell, in which case the adhesive foil comprises the interconnect and connects the overlap in order to mechanically connect and position the shingled solar cells. In addition, the present invention relates to a method for producing such solar cell strings.
