Summary:The invention relates to a spraying system for preparing a super-efficient solar cell electrode, and application thereof. The system comprises a slurry storage device (1), a spraying device (2) and amask (3), wherein the slurry storage device (1) and the spraying device (2) are connected through a pipeline, and the mask (3) is arranged between the spraying device (2) and a solar cell electrode. The system is characterized in that (1) fully mixing slurry; (2) manufacturing a seed layer; (3) manufacturing a conductive transmission layer; and (4) carrying out a co-firing process, wherein after agrid line (4) is manufactured, an electrode is heated and sintered so as to form the super-efficient solar cell electrode. Compared with the prior art, the manufactured multilayer electrode of the invention is good in electrode compactness and good in grid line electrode stacking leveling property, current transmission is facilitated, the precious metal consumption is reduced, the cost is greatlysaved, and the operation y
