Abstract
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.
Claims16
A polymer conductor sheet comprising
- (i) a polymer sheet comprising at least two adjacent zones within the same polymer sheet, which zones run in longitudinal direction of the polymer sheet, wherein
- (1) a first zone is sufficiently ductile and/or adhesive to fix the position of an elongated conductor on its surface facing the outside of the polymer sheet, and
- (2) a second zone adjacent to the first zone that has a different degree of polymerization and/or crosslinking than the first zone;
- and
- (ii) at least one elongated conductor positioned on the surface of the first zone facing the outside of the polymer sheet.
