Title:
FILM REMOVING PROCESSING METHOD AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/119784
Kind Code:
A1
Abstract:
A film removing processing method and device, the device comprising: an optical assembly, the optical assembly comprising a laser generator for generating laser beams; a first scanning mirror for reflecting laser beams, a second scanning mirror for reflecting the laser beams reflected by the first scanning mirror; and a focusing mirror for focusing the laser beams reflected by the second scanning mirror onto a thin-film solar cell for film removing processing; the device further comprising: a processor and a memory, wherein instructions are stored in the memory. When the instructions are executed by the processor, the following steps are implemented: moving the thin-film solar cell or the optical assembly to a designated position, and controlling the first scanning mirror and/or the second scanning mirror to deflect so as to carry out the film removing processing on the thin-film solar cell. The device improves film-removing rate and will not cause color difference.
