Example Embodiment
[0035] Example 1
[0036] This embodiment discloses an in-situ secondary printing device for electrode grid lines of photovoltaic solar cells, such as figure 1 As shown, a base 11, a silver paste carrier 1 and a silver paste carrier movement control device 6 are included.
[0037] Wherein, the base 11 is used to place the silicon wafer 4 that has been printed. Such as image 3 As shown, the number of printing of the silicon wafer is one or more than one, and the silicon wafer has gate lines 8 generated by printing.
[0038] Such as figure 2 As shown, the base 11 is provided with an adsorption device 10 through which the silicon wafer is adsorbed on the base. The adsorption device in this embodiment is a suction cup, and the adsorption force of the suction cup can ensure that the silicon wafer can be tightly attached to the base. The number and distribution position of the suction cups are not unique, as long as it can ensure that each part of the silicon wafer is uniformly stresse...
