The present invention is directed to solar cell strings () for photovoltaic modules comprising (i) a string of solar cells () facing each other in opposite polarity and shingled in string direction with or without partial overlap of solar cells (); (ii) at least one elongated electrically conducting interconnect () extending in string direction from one side of one solar cell to the opposite side of the next solar cell () for mechanically and electrically connecting the positive and negative electrodes of the shingled solar cells () in string direction on the alternating top and bottom sides of the solar cells, and (iii) at least two adhesives, optionally thermoadhesive foils () covering the at least one elongated interconnect () and at least part of the top or bottom side of each solar cell that comprises the elongated interconnect, with the proviso that (a) there is no horizontal gap between shingled solar cells, (b) the adhesives () do not contact each other, do not extend beyond one solar cell, do not extend into the optional partial overlap of solar cells (), and at least partially cover and mechanically fixate the at least one interconnect () to the solar cells ().

Solar cell string for use in a photovoltaic module

The present invention relates to polymer conductor sheets comprising zones featuring different degrees of polymerization and/or crosslinking within the same polymer sheet, wherein the zones differ, for example, in mechanical stability, ductility and/or (thermo)adhesiveness. The present invention also teaches devices comprising these zoned polymer conductor sheets such as solar cell strings, matrices and modules, uses thereof and methods for producing these.
