Embodiment 1

[0019] Embodiment one: with reference to attached figure 1 , where 1 is the glass substrate exposed after the battery undergoes edge insulation treatment, and the film layer removed by the edge treatment includes silicon-based series thin-film batteries, cadmium telluride series thin-film batteries, copper indium gallium tin series thin-film batteries or organic compound material thin-film batteries The back transparent conductive film, the photoelectric conversion layer and the front transparent conductive film; 2 is the edge insulation wire of the thin film solar cell, the inside of the insulation wire is the effective battery area, and the edge insulation treatment is performed outside. 3 is the ID preparation area reserved during the edge insulation treatment according to the prior design, and the ID area is outside the insulated wire and connected to the film layer in the edge-scanning area. The design and control of the ID area can be implemented through the software ope...

Embodiment 2

[0020] Embodiment two: with reference to attached figure 2 , where 1 is the glass substrate exposed after the edge insulation treatment of the battery, and the film layer removed by the edge treatment includes silicon-based series thin-film batteries, cadmium telluride series thin-film batteries, copper indium gallium tin series thin-film batteries or organic compound material thin-film batteries The back transparent conductive film, the photoelectric conversion layer and the front transparent conductive film; 2 is the edge insulation wire of the thin film solar cell, the inside of the insulation wire is the effective battery area, and the edge insulation treatment is performed outside. 3 is a small area for ID preparation reserved during the edge insulation treatment according to the prior design. The ID area is outside the insulating line and is not connected to the film layer in the edge-swept area. The design and control of the ID area can be implemented through the softw...

Embodiment 3

[0021] Embodiment three: with reference to attached image 3 , in order not to affect the performance and appearance of the battery, this area is generally designed outside the effective battery area of ​​the thin film solar cell. The production of ID is based on the pre-made ID character design through the software system of the laser edge sweeper, and the galvanometer scanning system of the laser edge sweeper is used to pass the high-energy-density laser through the glass substrate film to achieve the effect of displaying the ID. . In this diagram, the ID consists of numbers, English letters or other characters.

Abstract

The invention relates to a method for manufacturing thin film solar cell ID (identification) by using a laser edge deletion device, belonging to the technical field of thin film solar cells. The technical scheme of the invention comprises the following steps: carrying out edge insulation on the cell by using the laser edge deletion device; carrying out edge insulation in designed regions in advance; carrying out ID preparation according to a designedly reserved region, wherein the reserved region is outside an effective region of the thin film solar cell and can not affect the performances and appearance of the cell; and using the laser edge deletion device to prepare the ID in the region reserved in advance. The method provided by the invention is compatible with an existing production preparation process of the thin film solar cell without using a device specially used for ID marking, thus the input cost of devices can be greatly reduced; the method is applied to a series of silicon-based thin film cells, a series of cadmium telluride thin film cells, a series of copper indium gallium tin thin film cells or organic compound material thin film cells and the like; and the method has the simple manufacturing process, is easy to operate and control and can be utilized to effectively improve the work efficiency.

Description

Technical field: [0001] The invention relates to a method for manufacturing IDs of thin-film solar cells by using a laser edge sweeper, and belongs to the technical field of thin-film solar cells. Background technique: [0002] It has been confirmed by energy research authorities that the combination of photovoltaic arrays and buildings does not occupy additional ground space, making Building Integrated Photovoltaic (BIPV) buildings an important direction for large-scale use of photovoltaic technology in the world. Thin-film batteries in solar cells can perfectly realize building-integrated photovoltaics due to their unique aesthetic performance, stable and reliable power generation performance, low cost, and diverse design options. Therefore, research on thin-film batteries has attracted much attention. focus on. Taking amorphous silicon thin film battery as an example, its advantages are mainly reflected in: Stronger weak light response; More excellent high temperatur...
