Abstract
The invention relates to the field of solar PV (photovoltaic) manufacture and discloses a meshed plate for increasing the height of the electrode grid line of a solar battery. The meshed plate is only provided with a fine grid line structure and used for printing the electrode thin grid line of the solar battery. The meshed plate designed in the invention has a thin grid line structure, the arrangement position of the thin grid line is the same with the arrangement position of the thin grid line of a commonly-used meshed plate, and the width of the thin grid line is generally not greater than that of the fine grid line of the traditional meshed plate. After the solar cell substrate subject to one-step traditional printing is dried, the meshed plate designed in the invention is used for secondary printing, the height of the conductive paste fine grid line on the battery substrate is increased, and since the meshed plate dos not have a main grid line structure, conductive paste waste caused by repeated printing of the conductive paste main grid line on the substrate can be avoided.
