FIELD: physics.
SUBSTANCE: invention relates to solar cells and layers of material in said solar cells, as well as a method and a system for making solar cells. The solar cell contains at least one layer formed by laser ablation which forms a surface zone. The uniform surface zone, which must be formed, is at least 0.2 dm2 and the layer is formed by ultrashort laser pulses while scanning the laser beam using a rotating optical scanner having at least one mirror for reflecting the laser beam.
EFFECT: high efficiency of generating solar energy.
