SOLAR CELL AND METHOD FOR FABRICATING THE SAME

摘要

A solar cell and a method for fabricating the same are described. A pyramid structure is formed on a silicon substrate. A laser treatment is performed on the pyramid structure, so that a top portion of the pyramid structure has an arc shape, and a round is formed at a crest line of the pyramid structure. Films formed during subsequent processes hence have a uniform thickness and conversion efficiency of the solar cell is improved.
