Description
Technical Field
The invention relates to the technical field of testing of crystalline silicon solar cells, in particular to a novel screen pattern manufacturing method for screen printing production.
Background
With the establishment of carbon neutralization targets and the urgent need for environmental improvement, the solar energy industry is the most promising clean energy industry, and the development is rapid in recent years. Competition within the industry is becoming more intense. Manufacturers in the industry continuously explore ways to reduce production cost, and the ways are used for increasing enterprise competitiveness. Solar cells for power generation are the core of the solar industry. In the production process of the battery, the silver paste is an essential and expensive production auxiliary material. The reduction of the use of silver paste is always a goal constantly pursued by battery enterprise technicians. According to the invention, on the premise of not influencing the reliability of the product, the printing area of the pattern is reduced and the slurry permeability is reduced by optimizing the printed pattern, so that the use amount of the slurry is reduced, the production cost can be effectively reduced, and the enterprise income is increased.
Disclosure of Invention
In order to solve the problems, the invention provides a novel screen pattern manufacturing method for screen printing production.
In order to solve the technical problems, the technical scheme provided by the invention is as follows: the invention relates to a novel screen printing plate graph for screen printing production, which is designed to optimize a connecting line between PAD points, reduce the length of the connecting line and save silver paste under the condition of not influencing current collection. Meanwhile, obviously, the shading area of the front face of the battery is reduced due to the reduction of the patterns, so that the light receiving area of the battery can be increased, and the power generation efficiency is improved.
The invention relates to a novel screen pattern manufacturing method for screen printing production, which comprises the following manufacturing steps:
the method comprises the following steps: designing a pattern on the surface of a screen printing plate for printing;
step two: changing a connecting line between every two PAD points of the graph from a penetrating main grid connecting line to an interrupted main grid connecting line;
preferably, the connection mode is changed from a penetrating mode to an intermittent mode.
Compared with the prior art, the invention has the advantages that: the invention improves the design graph of the screen printing plate, and the positive silver paste is printed on the surface of the battery with less use amount, thereby reducing the consumption of the positive silver paste. The single-chip battery has small generating capacity and has no practical significance in the actual use process. In order to meet the daily production requirement, each battery piece needs to be connected in series by a welding strip with the diameter of 0.3mm, and the currents generated by the batteries are connected in series so as to improve the power generation power of the battery pieces. The front surface of the battery piece is provided with a rectangular PAD point, and the welding strip is bonded at the PAD point and has certain tensile resistance. The connecting line between the PAD points does not contribute to the tensile force, and only transmits the current. But the connecting lines are also formed by printing and sintering silver paste. A portion of the silver paste is consumed. The design of the invention optimizes the connecting line between PAD points, reduces the length of the connecting line and saves silver paste under the condition of not influencing current collection. Meanwhile, obviously, the solar cell converts light energy into electric energy, and the shading area of the front side of the cell is reduced due to the reduction of the patterns, so that the light receiving area of the cell can be increased, and the power generation efficiency is improved.
