Film removing processing method and equipment

Abstract

The embodiment of the invention discloses a film removing processing method and equipment. The equipment comprises an optical component. The optical component comprises a laser generator which is usedfor generating laser beams; a first scanning mirror which is used for reflecting the laser beams; a second scanning mirror which is used for reflecting the laser beams reflected by the first scanningmirror; and a focusing mirror which is used for focusing the laser beams reflected by the second scanning mirror on the solar cell and performing film removing processing on the solar cell. The equipment also comprises a processor and a memory. The instruction is stored in the memory. The following steps are realized when the instruction is performed by the processor: the solar cell or the optical component is move to the designated position, the first scanning mirror and the second scanning mirror are controlled to deflect and the solar cell is also controlled to move so as to perform film removing processing on the solar cell. The film removing rate can be enhanced without producing aberration.

Description

technical field [0001] The invention relates to photovoltaic technology, in particular to a film removal treatment method and equipment. Background technique [0002] Photovoltaic power generation is a recognized clean energy. In recent years, photovoltaic power generation has been strongly supported by national policies. As a film-removing photovoltaic module, it is widely used in combination with buildings and automobiles because it can generate electricity and light, that is, BIPV (Building Integrated Photovoltaic), solar photovoltaic power generation system (BAPV) attached to buildings , Building Attached Photovoltaic), etc. At present, the film removal of thin-film solar cells mostly adopts the laser scribing method, that is, the laser is used to remove a certain proportion of the non-removable film layer to achieve the film removal effect, but the traditional laser film removal scribing generally uses the engraving of the motor to drive the laser head.

At present, the film removal of thin-film solar cells mostly adopts the laser scribing method, that is, the laser is used to remove a certain proportion of the non-removable film layer to achieve the film removal effect, but the traditional laser film removal scribing generally uses the engraving of the motor to drive the laser head. Line method, or when the laser beam is not moving, it is realized by the reciprocating reciprocating method of the battery. mm / s), and the spot diameter or spot width is generally limited to about 50 microns (μm) to 100 μm, so the film removal rate is low. On the other hand, traditional laser film removal scribing will use multiple Two laser heads are processed at the same time, because the performance of each laser is different, different processing areas are prone to chromatic aberration
