COATING ON A FIBER SUBSTRATE AND A COATED FIBER PRODUCT

摘要

The present invention relates generally to solar cells, material layers within solar cells, a production method of solar cells, and a manufacturing arrangement for producing solar cells. A solar cell according to the invention includes at least one layer with a surface, produced by laser ablation, wherein the uniform surface area to be produced includes at least an area 0.2 dm2 and the layer has been produced by employing ultra short pulsed laser deposition wherein pulsed laser beam is scanned with a rotating optical scanner including at least one mirror for reflecting the laser beam.
