Description

technical field

[0001] The invention relates to the technical field of photovoltaic crystal silicon cells, in particular to a step-by-step printing device for photovoltaic crystal silicon cells. Background technique

[0002] Photovoltaic crystalline silicon cells have always been developing toward improving conversion efficiency and reducing costs, but the optimization of the aspect ratio of the sub-grid lines in the existing photovoltaic crystalline silicon cell production process has received relatively great attention, but the traditional printing process will sub-grid The synchronous printing of the line and the main grid line will cause the printing of the main grid line position to be repeated, and at the same time reduce the electrical performance of the photovoltaic crystalline silicon cell. Contents of the invention

[0003] The purpose of the present invention is to provide a step-by-step printing device for photovoltaic crystalline silicon cells to solve the pro...
