Description
Technical field
The utility model relates to solar components technical field, is specifically related to a kind of solar components.
Background technology
After solar battery sheet connects by welding, by welding transmission current, but along with the attenuation day by day of cell piece thickness, by the stress that between welding and cell piece, the rising-heat contracting-cold before and after welding produces, be easy to cause cell piece to break, significantly increase the loss of photovoltaic module, welding in conventional photovoltaic assembly is located at cell piece tow sides, welding is subject to irradiation, the useful life of welding is lower, cell piece front has welding can cause photoelectric conversion loss to a certain degree, that is to say that positive welding can block a part of cell piece, this has affected the photoelectric conversion efficiency of solar components.
Utility model content
For solving the problems of the technologies described above, the purpose of this utility model is to provide a kind of solar components, makes welding all be welded in the cell piece back side, reduces the stress after welding, reduces breaking of cell piece, extends the useful life of welding.
For achieving the above object, the technical solution of the utility model is as follows: a kind of solar components, comprise concavo-convex welding body, described concavo-convex welding body equal intervals is provided with recessed, the radian projection of described recessed side for making progress, described recessed number and described radian projection number are at least one, described concavo-convex welding body is located on a slice cell piece, punch at pad place in described cell piece front, the contact in described cell piece front is guided to the described cell piece back side by hole, with the recessed block welding of the concavo-convex welding at the described cell piece back side.
Preferably, described recessed is 4, and described radian projection is 4.
Preferably, described recessed is 3, and described radian projection is 3.
Preferably, the thickness of described concavo-convex welding body is 0.08mm-0.5mm.
Preferably, the width of described concavo-convex welding body be 1mm and more than.
Adopt the beneficial effect of above technical scheme to be: because welding body is provided with radian projection, can reduce the stress that expands with heat and contract with cold and produce before and after welding of battery film, because welding body is provided with recessed, the contact in cell piece front can be incorporated into the cell piece back side, all like this weldings are all layed in the cell piece back side, front does not have welding, there will not be welding to block the problem of a part of cell piece, cell piece photoelectric conversion efficiency has improved, also extended the useful life of welding simultaneously, and battery front side homogeneous, attractive in appearance, meets consumer's aesthetic requirement.
