Inkjet printing process for solar battery plate grid line

Abstract

The invention discloses an inkjet printing process for a solar battery plate grid line, which determines printing parameters including the inkjet amount of an inkjet printing sprayer, the moving distance of the sprayer, relative moving routes of the sprayer and a battery plate and the like according to the number, length, thickness and distance of the battery plate grid line, and then spray slurry onto the surface of a battery plate by the sprayer according to the determined printing parameters to realize different grid line patterns. Because no net plate is required, the printing yield is improved; the probability of defective printing products caused by the net plate is reduced; the labor power is reduced; the raw material is saved, the profit is increased; the time for feeding back defective printing is shortened; and the power consumption and environment pollution are reduced.

Description

technical field [0001] The invention relates to a metallization process of a solar cell, in particular to an ink-jet printing process for grid lines of a solar cell. Background technique [0002] The traditional screen printing technology needs to design and manufacture the screen in advance, and realize different grid line patterns through different screen designs. Changing the number, spacing, length, width, thickness or shape of the grid lines requires redesigning and manufacturing the stencil. In the production process, the damaged screen should be replaced frequently. [0003] Disadvantages of screen printing technology: First, the design and manufacturing process of the screen board takes about a week, which takes a long time, and the problems in the printing line cannot be fed back in time; secondly, the cost of manufacturing the screen board increases the production cost of solar cells; The damaged stencil needs to be replaced during the process, which reduces the ...

[0003] Disadvantages of screen printing technology: firstly, the design and manufacture process of the stencil takes about a week, which takes a long time, and the problems in the printing line cannot be fed back in time; secondly, the cost of manufacturing the stencil increases the production cost of solar cells; The damaged stencil needs to be replaced during the process, which reduces the printing output per unit time and increases labor costs, which affects the profits of solar cell companies; at the same time, the production of stencils also has energy consumption and environmental pollution.
