Technical field
The utility model relates to area of solar cell, in particular, relates to a kind of novel solar cell positive electrode half tone graphic structure.
Background technology
Solar energy is to clean, do not have forever and end most regenerative resource, is that the PN junction type solar cell technology of material has obtained flourish with the semiconductor silicon.But solar-photovoltaic technology will be realized the par online, will realize popularization and application that it is imperative further to reduce cost.The making of silicon solar cell is substrate with the semiconductor silicon material, produce the matte of Pyramid on its surface, utilize diffusion technique to make PN junction again, carry out the edge etching then, utilize plasma P ECVD coating technique to penetrate film again, realize the making of electrode at last by the silk screen printing sintering technology at its surface plating one deck passivated reflection reducing.
Screen printing technique is made electrode, comprises positive electrode and negative electrode, and it mainly acts on is with the inner electric current collection that produces of semiconductor photovoltaic cells, and is drawn out to external circuit.By positive and negative electrode, the interconnected welding of single photovoltaic cell can be increased power output.The material of making positive electrode is called the silver slurry, is a kind of electrocondution slurry of being made up of noble metal silver powder, binding agent frit, organic carrier etc., and electric current is by the silver-colored crystal grain transmission of recrystallization on silicon emitter.Good electrode performance, require silver electrode good the contact to be arranged with test probe, silver electrode must possess good soldering reliability energy, the power loss that the silver electrode series resistance causes is little, the price that performance requirement that these are concrete and silver powder itself is expensive, cause silver slurry price always in high position operation, silver slurry cost also becomes the important component part of crystal-silicon solar cell manufacturing cost.
If can reduce the silver slurry consumption in the battery production manufacture process, just must reduce the cost that battery production is made, tend to cause battery performance to descend but blindly reduce silver slurry consumption, cause the result who loses more than gain.Therefore, how carrying out the design optimization of electrode pattern, to guarantee to obtain excellent battery performance again when silver slurry consumption reduces in the battery production process, is an important problem.
The utility model content
The utility model provides a kind of novel solar battery positive electrode at the technical problem of above-mentioned existence, reduces the silver slurry consumption in the battery production manufacture process, simultaneously the good solar cell of obtained performance.
For achieving the above object, the technical solution adopted in the utility model is as follows:
A kind of novel solar battery positive electrode, described solar cell positive electrode figure comprises main grid line, secondary grid line and frame line, wherein, main grid line quantity is more than 2, secondary grid line is some, the main grid line is vertical mutually with secondary grid line, is parallel to each other between the secondary grid line, and frame line is parallel to the main grid line, is connected perpendicular to secondary grid line and with secondary grid line; Main grid line main part is the silver paste printing zone with engraved structure, and secondary grid line passes the engraved structure of described main grid line.
The engraved structure of described main grid line main part is included in the multistage openwork part that inserts in the main grid line, described each section openwork part comprises five zones, be respectively: the silver paste printing zone of mid portion, toward both sides are hollow out zones, are silver paste printing zones toward both sides again, these five zones constitute one section openwork part.
The gradual change design is adopted at described main grid line two ends, and the width of end points is less, widens into consistent with the main part width more gradually.
Described multistage openwork part equidistantly is inserted in the main grid line.
The beneficial effect that technical solutions of the utility model are brought is as follows:
Main grid line main part adopts the design of engraved structure to greatly reduce the use amount of positive silver paste, reduces production costs; Symmetry segmentation hollow out formula structure has been beautified the battery outward appearance; The design that comprises the openwork part in five zones increases effective light-receiving area, improves photogenerated current, promotes photoelectric conversion efficiency, thus the solar cell of availability excellence.
