With the emerging and widespread use of screen printing meshs. The battery version has also been used. Because it can improve the performance of the battery. This is a good choice for the cell manufacturing industry. The requirements for the quality of printed film are also constantly improving, and only in this way can the economic benefits of the industry be improved.
The crystalline silicon solar cell prints the screen pattern on the front side of the battery by screen printing technology, and the printing technology is very mature. By optimizing the screen printing pattern, including the fine grid line and the main grid line, to improve battery efficiency and reduce cost, it is an important way to finally achieve parity online. Screen printing technology is very mature, especially with the development of the networkless screen technology. Although the gate line refinement of the screen pattern has been advanced, the printing quality of the positive electrode silver paste limits the continued refinement of the printed pattern. The development of positive electrode silver paste takes time. From the time of laboratory development to mass production, it is determined that the contribution of positive electrode silver paste to gate line refinement is step-by-step progress. However, the photovoltaic solar market has always forced the continuous advancement of battery technology, which is also the process of photovoltaic solar energy.
Screen-printed front gate lines form a good ohmic contact with silicon, collecting electrons, holes and being exported to an external circuit. Therefore, in order to improve ohmic contact and electron transport capability, necessary gate line refinement and number of lines are required. The increase, that is, the refinement and densification of the metallization gate line, increases the cross-sectional area of the gate line while reducing the width of the gate line, reduces the light-shielding area of the front gate line, and improves the contact performance of the front silver paste.
