Description

Technical Field

[0001] The utility model belongs to the technical field of electrode screen printing, in particular to a positive electrode screen with adjustable grid line spacing. Background Art

[0002] The grid line of the photovoltaic panel is the busbar of the crystalline silicon cell. The power generation principle of the crystalline silicon cell utilizes the photovoltaic effect, which forms a potential difference at the PN junction and establishes a built-in electric field. However, there is voltage but no current flow, and wires are needed to conduct the electricity out. The grid line is the first-level wire that carries the current. The grid line collects the current to the busbar, which is then connected to the junction box and finally conducted out by the cable of the junction box. After printing, in order to improve the durability of the grid line, it is usually necessary to apply slurry on it. However, due to the different distances between the grid lines, it is inconvenient to apply the slurry. A device that is convenient for adjusting the spacing is now proposed. Utility Model Content
