Fabrication of surface textures by ion implantation for antireflection of silicon crystals
Abstract:
The invention relates to a new method of texturing silicon surfaces suited for antireflection based on ion implantation of hydrogen and heavy ions or heavy elements combined with thermal annealing or thermal annealing and oxidation. The addition of the heavy ions or heavy elements allows for a more effective anti-reflective surface than is found when only hydrogen implantation is utilized. The methods used are also time- and cost-effective, as they can utilize already existing semiconductor ion implantation fabrication equipment and reduce the number of necessary steps. The antireflective surfaces are useful for silicon-based solar cells.
