Abstract: The present disclosure provides a processing method for a photovoltaic cell and a string welding and curing device for a photovoltaic cell. The method includes step S1: plating both side surfaces of a monocrystalline silicon wafer; Step S2: forming a first electrode on one side surface of the plated monocrystalline silicon wafer; Step S3: forming a second electrode on the other side surface of the plated monocrystalline silicon wafer, to form a cell sheet; and Step S4: string welding a plurality of cell sheets and at the same time, curing the first electrode and the second electrode, by using a string welding and curing device for a photovoltaic cell. With the processing method provided by the present disclosure, the electrodes on the cell sheets can be cured while the cell sheets are string welded. It can save resources, shorten the processing time of the photovoltaic cell, and improve the production efficiency.

Abstract: An embodiment of the present disclosure discloses a method and device for film removing process. The device includes: an optical assembly. The optical assembly includes: a laser generator for generating a laser beam; a first scanning mirror for reflecting the laser beam; a second scanning mirror for reflecting the laser beam reflected by the first scanning mirror; and a focusing mirror for focusing the laser beam reflected by the second scanning mirror onto a thin film solar cell for film removing process. The device further includes a processor and a memory in which instructions are stored, and the following steps are implemented when the instructions are executed by the processor: 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 be deflected so as to perform a film removing process on the thin film solar cell.
