Abstract

The invention relates to the technical field of solar power generation, in particular to a solar cell panel and a manufacturing method thereof. The problem is solved that in the prior art, the short circuit of single cells is caused by abnormal electrode scribing and even a solar cell panel has the risk of scrapping. The solar cell panel comprises a substrate, a first electrode layer, a photoelectric conversion layer, a second electrode layer sequentially stacked on the substrate and N groups of grooves sequentially arranged in the first direction. Each group of grooves comprises a non-abnormal first groove, a second groove and a third groove which are sequentially arranged in the first direction, wherein the non-abnormal first groove penetrates through the first electrode layer, the second groove penetrates through the photoelectric conversion layer, and the third groove penetrates through the photoelectric conversion layer and the second electrode layer. At least one of the N groupsof grooves further comprises an abnormal first groove, wherein the abnormal first groove is located between the non-abnormal first groove and the second groove in the group.

Description

technical field [0001] The invention relates to the technical field of solar power generation, in particular to a solar battery panel and a preparation method thereof. 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. In the process of preparing solar panels, it is often a problem that the solar panels are scrapped due to incomplete marking of the electrodes, which causes a short circuit between the cells. Contents of the invention [0003] The main purpose of the present invention is to provide a solar battery panel and its preparation method, which solves the problem in the prior art that abnormal electrode marking causes a short circuit between single cells and even makes the solar battery panel face the risk of being scrapped. [0004] ...
