Zusammenfassung:	PURPOSE: A solar cell and a manufacturing method thereof are provided to improve the insulation properties of the solar cell by removing a by-product generated in laser scribing through an overlapping process. CONSTITUTION: A back electrode(121) is formed on a substrate(110). A diffusion barrier(122) is formed on the back electrode. A first laser scribing is performed on the back electrode. A second laser scribing is performed to remove a by-product generated by the first laser scribing. A third laser scribing is performed to remove the by-product. [Reference numerals] (AA) Laser
