Abstract
The invention discloses a film structure for a solar crystalline silicon battery slice and a printing screen of the film structure. Two frame lines, which are parallel to main grid lines, of a printing pattern on the film structure and the printing screen are wave lines, the wavelength of each wave line is 0.05-3.0mm, and the amplitude is 0.05-0.5mm. According to the film structure for the solar crystalline silicon battery slice and the printing screen of the film structure, the frame lines of the printing pattern are in a wave line design, and in the prepared printing screen, an included angle of 10-30 degrees is formed at an overlapping position of a netting wire and the corresponding frame line, thus the phenomenon that the overlapping positions of the frame lines of the printing pattern and the corresponding netting wires are completely blocked by the netting wires is prevented, the printing permeability is ensured, loss of the photoelectric conversion efficiency of the crystalline silicon battery slice caused by grid breaking and EL addition is prevented, the poor appearance caused by too thick frame lines is prevented, the slurry weight of a single battery slice is lowered, and the slurry cost of a battery slice manufacturer can be saved by above 20 percent.
