The main grid is generally made of silver paste, so that the price is high, and the non-silicon cost is greatly influenced, so that the non-main-grid battery concept is provided in the industry. The company that originally proposed the concept of no main grid, used printing fine grids after coating, without printing the main grid, and covered a layer of polymer film embedded with copper wires on the front surface of the cell, and in the subsequent lamination process of the components, the pressure and temperature of the laminator helped the copper wires and the fine grids to bond together. Although the cost and the production process of the slurry can be greatly reduced and the shading area of the surface of the battery can be reduced, the battery cannot be shifted due to the fact that the I-V test cannot be carried out on the battery without the main grid in the whole process, and the defects that a bright piece and a dark piece of the component are generated or the component is repaired for many times when the battery reaches the end of the component can be overcome, and the rate of finished products and the production efficiency of the component are seriously influenced.
