Abstract

The invention relates to the technical field of solar power generation and in particular relates to a repairing method for laser marking-off anomaly of a solar cell panel and the solar cell panel, aiming at solving the problems in the prior art that single cells are short-circuited due to the laser marking-off anomaly, even the solar cell panel is confronted with scraping. According to the repairing method for the laser marking-off anomaly of the solar cell panel, the solar cell panel is divided into a plurality of the single cells which are connected in series along a first direction throughlaser marking-off; the method comprises the following steps: determining a marking-off position of a first short-edge insulation line again according to a position of a region with the laser marking-off anomaly; marking off the insulation line again at the marking-off position of the first short-edge insulation line, which is determined again, so as to obtain a second short-edge insulation line toisolate the region with the laser marking-off anomaly from a region enclosed by the second short-edge insulation line and other original insulation lines except the first short-edge insulation line,wherein the first short-edge insulation line is any one short-edge insulation line parallel to a first direction in the original insulation lines.

Description

technical field [0001] The invention relates to the technical field of solar power generation, in particular to a method for repairing abnormal laser marking lines of a solar battery panel and a solar battery panel. Background technique [0002] In the production process of solar panels, laser scribing and three-layer coating is one of the important links, so as to divide a large solar panel into multiple single cells connected in series in order to increase the output voltage of the solar panel. [0003] see figure 1 , figure 2 with image 3 , There are three layers on the substrate 1 of the solar cell panel: the conductive film layer 2 of the front electrode, the photoelectric conversion layer 3 and the conductive film layer 4 of the back electrode. In the actual production process, when the front electrode conductive film layer 2 is formed by coating on the substrate 1, the front electrode conductive film layer 2 is scribed by the first laser scribe line to form a P1 ...
