Embodiment
[0038] A spraying system for ultra-efficient solar cell electrode preparation, such as figure 1 , the system includes a slurry storage device 1, a spraying device 2 and a mask 3 to avoid contamination of areas other than the grid lines 4, the slurry storage device 1 and the spraying device 2 are connected by pipelines, and the mask 3 is located between the spraying device 2 and the solar energy between the battery electrodes.
[0039] The solar cell electrode includes a grid line 4 , a carrier 5 and a substrate 6 , the grid line 4 is located above the carrier 5 , the carrier 5 is located above the substrate 6 , and the mask 3 is arranged between the spraying device 2 and the carrier 5 . Disperse the slurry in the slurry storage device 1, keep the slurry in a spin bleaching state, and then spray the slurry through the mask 3 through the spraying device 2, so that the grid lines 4 are formed on the carrier 5, and then the ultra-high-efficiency solar cell is produced electrode....
