Description
Technical Field
The invention belongs to the technical field of solar cells, and relates to a screen printing plate design and a printing method for screen printing of sliced solar cells.
Background
Compared with the traditional full-size solar cell module, the sliced solar cell module can improve the generating power of the module by reducing resistance loss. According to ohm's law, the electrical loss of the solar cell interconnection is proportional to the square of the current magnitude. If the battery is cut into halves, the current is also reduced by half, and the electric loss is reduced to one fourth of the loss of the full-size battery. Therefore, the dicing of solar cell modules becomes more and more important. In addition, more and more enterprises use larger silicon wafers as solar cells, such as 210mm × 210mm silicon wafers, which are usually cut into three pieces, while the shingle assembly requires that one solar cell be cut into multiple pieces. It is anticipated that the market share of sliced solar modules will be greater and greater.
In the conventional slicing process, after the full-size solar cell is prepared, the whole solar cell is cut into two, three or more slices by laser. However, laser cutting may additionally introduce damage on the cut surface, resulting in very severe recombination loss, reducing the photoelectric conversion efficiency at the cell level. For example, the efficiency of a conventional PERC cell after half-cutting is reduced by about 0.1-0.2% abs, and the efficiency of a Topcon cell after half-cutting is reduced by about 0.2-0.3% abs. In view of this, more and more people have proposed a method of slicing during the battery manufacturing process and then passivating the cut edge, which can effectively reduce the recombination loss of the cut edge, thereby improving the battery efficiency. If the method is applied to mass production, some processes need to be adjusted accordingly in order to reduce the influence on the production capacity, including passivation, screen printing, and the like.
