[0002] During the production of perovskite cells, the substrate needs to be scratched, and one beam of light needs to be split into multiple beams to improve the scratching efficiency. However, the split beams cannot be used directly for scratching. Each beam needs to be focused, and a focusing device is needed at this time. The existing focusing device allows staff to move the focusing mirrors so that the spacing between the focusing mirrors changes to adapt to the spacing between the laser beams. However, this adjustment method does not have a precise gap adjustment device, and the spacing adjustment error between the focusing mirrors is relatively large. The focusing mirror often cannot fully adapt to the laser spacing, and the light beam cannot be focused on the center of the focusing mirror, resulting in poor focusing effect. The inconsistent power of each light beam leads to low scratching efficiency, affecting the scratching quality.
