Description
Technical field
What the present invention relates to is the electrode of solar battery printing process, and what be specifically related to is a kind of supporting metallic solar energy web plate and using method thereof for repeatedly printing.
Background technology
Fast development along with economy, the consumption of the energy is increasing, the storage capacity of the non-renewable resources such as coal and oil reduces day by day, and this impels people that new forms of energy (as nuclear energy, solar energy, wind energy, biomass energy, geothermal energy, ocean energy, Hydrogen Energy etc.) are constantly explored.Wherein, as the source of many energy on the earth, solar energy has occupied consequence in the research of new forms of energy, and solar cell is exactly a core representative of Application of Solar Energy.
The transformation efficiency that improves solar cell is a main target of present solar cell research, except the improvement to the selection of cell substrate material, substrate manufacture craft, the electrode of solar battery of making excellent performance also can bring to the transformation efficiency of battery good effect.
Figure 1 shows that the structure of traditional monolithic solar energy web plate, it consists of by the some main grid lines 11 that are parallel to each other and some thin grid lines 12 that are parallel to each other are mutually vertical.Traditional solar energy web plate is that silk screen photosensitive emulsion combines and makes, but the silk screen photosensitive emulsion web plate is not because resolving power is fine, thereby is difficult to further improve its gate electrode line printing quality again.Good resolving power refers to that half tone can accurately show the hachure of original copy, and this requirement to the web plate material is very high.The trend of the oriented metal mold web plate of solar energy web plate future development in recent years, the resolving power of metal mold solar energy web plate is high, but its character is more crisp, particularly at the easy fracture in the junction of main grid line and thin grid line, is restricted at web plate grid line place in its life-span.This has increased the cost of manufacture of solar cells to a certain extent for large-scale production.
Summary of the invention
The technical problem to be solved in the present invention is the problem of above-mentioned metal mold web plate grid line easy fracture when printing.
For solving the problems of the technologies described above, the invention provides a kind of supporting metallic solar energy web plate for repeatedly printing, it comprises two blocks of web plates; Have at least one to be the metal mold web plate in described two blocks of web plates; First block of web plate of described two blocks of web plates only has thin grid line structure, and second block of web plate only has the main grid line structure; Described each thin grid line of first block of web plate be link up or have breakpoint with second web plate main grid line corresponding position; When there was breakpoint in the thin grid line of described first block of web plate, the spacing of breakpoint was not more than the main grid line width of second block of web plate.
Printing process corresponding to the above web plate is: be used alternatingly described two blocks of web plates and carry out the grid line printing on silicon chip.As preferably, the order of print positive electrode grid line is: first adopt first screen printing to go out thin grid line, after drying is processed, adopt again second block of web plate to carry out the printing of main grid line, oven dry, can adopt again as required the above web plate to repeat print, enter next process after finishing printing.
Supporting metal mold solar energy web plate provided by the present invention, the main grid line separates design with thin grid line, can effectively solve the problem of single piece of metal type web plate main grid line and thin grid line junction easy fracture, use this web plate printing effectively to extend the service life of web plate, thereby reduce production costs.
