Abstract:
Methods for cleaning a side edge of a thin film photovoltaic substrate utilizing a laser are provided. The method can include transporting the substrate in a machine direction to move the substrate past a first laser source, and focusing a first laser beam generated by the first laser source onto the side edge of the substrate such that the laser beam removes the thin film present on the side edge of the substrate. An apparatus is also generally provided for cleaning a first side edge and a second side edge of a thin film photovoltaic substrate.
