Thin-film solar cell two-dimensional code etching device and etching method

Abstract

The application provides a thin-film solar cell two-dimensional code etching device, and provides a thin-film solar cell two-dimensional code etching device, which comprises a laser optical system, a material receiving reel, a material feeding reel, a tape sensor, a plurality of tensioning directional wheels and the like, and has the advantages of simple and compact structure and continuous operation capability. The device can edit the layout of the required mark in a self-defined mode, and can sputter the two-dimensional code information and the required mark information onto the surface of the glass by etching, so that the glass product is not damaged. The application also provides a thin-film solar cell two-dimensional code etching method, in which the near-infrared laser with a pulse width of nanoseconds is integrated and focused by using an optical system, and the high-temperature-resistant high-molecular material coated on PET or PEF is transferred to the surface of the glass by using a vibrating mirror scanning technology, so that the two-dimensional code and the related mark characters are obtained. The method has the characteristics of fast processing speed, stable process, easy maintenance, simple tape replacement and cost saving.
