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 dm 2 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. |
