Abstract
The invention discloses a process for introducing steel plate printing onto an ordinary production line of solar cells. The solar cells are printed by using the conventional production line, so that the printing height-width ratio is ensured, the printing quality of the cells is ensured, and the cell converting efficiency is increased. The process comprises the following steps: I, performing all-aluminum back field printing on the solar cells without leaving a back electrode position; II, after back field printing is finished, drying the cells at the temperature of 200-300 DEG C; III, in the all-aluminum back field, printing positive electrode main grids of the cells, and drying the cells at the temperature of 200-300 DEG C; IV, in the all-aluminum back field, printing the positive electrode secondary grids of the cells, and drying the cells at the temperature of 200-300 DEG C; V, sintering the cells obtained in the step IV; VI, grinding the cells obtained in the step V by means of friction, and welding a back electrode on the back field by adopting a tin welding way under an anaerobic condition. Only one steel plate printing machine is adopted, so that the resources are saved greatly, the process is simplified, and the production efficiency is increased.
Description
Technical field
The present invention relates to solar battery sheet typography, be specifically related to a kind of technique of utilizing conventional steel plates printing production line printing solar cell product; Be specifically related to the technique to later stage cell piece back surface field processing welding back electrode.
Background technology
In solar cell production process, common serigraphy is because silk thread exists the phenomenon that interweaves, when the higher slurry of printing viscosity, easily cause network blocking phenomenon, the method of existing solution problems, generally with reducing slurry viscosity, or increase half tone grid line opening, but preceding method is all unfavorable for improving the depth-width ratio of printing lines, cause cell piece electricity conversion lower, and existing typography needs at least 4 printing machines just can complete typography, cause wasting of resources rate too high, and complicated operation, error is larger, be unfavorable for the maximization that cell piece brings benefits.
Summary of the invention
For addressing the aforementioned drawbacks, solve the silk thread network blocking phenomenon causing that interweaves that traditional silk-screened exists, and solve the problem that the more printing machine of needs in traditional printing technique just can complete, the present invention is by adopting traditional steel plate printing machine and by adopting special typography to address the above problem, and by improving the technique that arranges of back electrode, solve tradition and produce the problem that line cannot use steel plate to print, technique of the present invention is simple, easy to operate, effectively solve prior art problem, and can economize on resources, produce larger economic benefit.
For achieving the above object, the present invention by the following technical solutions: a kind of solar battery sheet steel plate typography, comprise steel plate printing machine, utilize traditional steel plate printing machine according to following steps order printing solar cell sheet:
Step 1, carries out the printing of full aluminium back surface field by solar battery sheet, and backplane position is not stayed at backplane place;
Step 2 after back surface field is completed for printing, is dried cell piece under the condition of 200-300 DEG C;
Step 3, under full aluminium back surface field, printing cells positive electrode main grid is then dried cell piece under the condition of 200-300 DEG C;
Step 4, under full aluminium back surface field, the secondary grid of printing cells positive electrode are then dried cell piece under the condition of 200-300 DEG C;
Step 5, carries out sintering by the cell piece of step 4 gained;
Step 6, carries out Friction Sanding to the cell piece of step 5 gained, and under anaerobic adopts the mode of soldering in back surface field, to weld back electrode.
Preferably, described steel plate printing, its steel plate printing opening is 30,100 of thin grid numbers, steel plate thickness 35um.
Compared with prior art, the present invention has following beneficial effect: interweave because steel plate printing machine does not have silk screen, therefore by adopting steel plate printing machine effectively to solve the ever-present network blocking problem that interweaves in traditional printing technique; Solve by back electrode setting being placed on to last processing step the problem that conventional steel plates printing cannot be applicable to conventional solar cells and produces line; And the present invention only adopts a steel plate printing machine can complete typography, save greatly resource, and simplify typography, greatly improve production efficiency, and the cell piece that uses this technique to make has effectively ensured the optoelectronic transformation efficiency of cell piece, has therefore improved greatly economic benefit.
