摘要: A method for fabricating a solar cell. The method includes providing a thin metallic substrate in roll form. The method also includes applying an abrasive grit to a surface of the thin metallic substrate. The method includes mechanical-polishing the surface with the abrasive grit such that the surface is polished to remove at least one defect from the surface. Mechanical-polishing the surface of the thin metallic substrate is by a roll-to-roll polishing process of the surface of the thin metallic substrate. Moreover, the method includes depositing an absorber layer of the solar cell on the thin metallic substrate.
