Abstract
The utility model relates to a novel thin film solar cell photovoltaic solder strip device, which comprises a strip body extending longitudinally, wherein the strip body includes a copper strip, of which the outside is provided with a tin coating layer, and the strip body is 60-130 microns thick and 1.5-8 microns wide. The novel thin-film solar cell photovoltaic solder strip device provided by the utility model matches with a thin-film cell in thickness so that the thickness of a thin-film cell photovoltaic module is reduced. A solder strip is made high in weldability and tensile strength, and both the elongation and resistivity of the solder strip can fully meet the needs of engineering applications.
Description
Technical field
The utility model relates to a kind of welder of used for solar batteries, relates to the invention of a kind of novel thin film solar cell photovoltaic welding device aspect or rather.
Background technology
Solar cell photovoltaic welding device is the welder that is used on the photovoltaic module, mainly plays the effect that connects conduction.The critical technical parameter of welding device comprises solderability, tensile strength, elongation, resistivity.Welding device commonly used at present is that the method that is coated with tin through heat is prepared from the copper strip surface of a kind of high-elongation, high tensile, high conduction, and the thickness of welding device reaches 0.8 millimeter, and it is folding to be unfavorable for curling.Portable photovoltaic battery is a great development trend of photovoltaic product; This just requires the photovoltaic product more and more thinner; Even become and can curl foldingly, so also requiring the also correspondingly attenuation of core corollary apparatus of photovoltaic product, the blocked up laminating technology that also causes easily of welding device goes wrong simultaneously; Thus, existing photovoltaic welding belt device can not satisfy the growth requirement of photovoltaic product.
This shows that above-mentioned existing photovoltaic welding belt device still has many defectives, and demands urgently improving.
Because the defective that above-mentioned existing photovoltaic welding belt device exists; The design people is based on being engaged in this type of product design manufacturing for many years; Long-pending have abundant practical experience and professional knowledge, actively studies innovation, in the hope of founding a kind of novel thin film solar cell photovoltaic welding device that improves molding structure; Can improve general existing on the market conventional photovoltaic welding belt device molding structure, make it have more competitiveness.Through constantly research, design, and after studying sample and improvement repeatedly, found out the utility model of true tool practical value finally.
Summary of the invention
The utility model technical problem underlying to be solved is; Overcome existing solar cell photovoltaic welding device thickness and can not mate the defective that satisfies the existence of solar cell attenuate; And a kind of novel thin film solar cell photovoltaic welding device of new structure is provided, make the reduced thickness of its photovoltaic welding belt.
The utility model solves its technical problem underlying and adopts following technical scheme to realize.According to the novel thin film solar cell photovoltaic welding device that the utility model proposes, include the belt body of longitudinal extension, belt body comprises copper strips, is provided with in the copper strips outside and is coated with the tin layer, and the thickness of belt body is 60 microns to 130 microns, and width is 1.5 millimeters to 8 millimeters.
The utility model solves its technical problem and can also adopt following technical measures further to realize.
Before the cross section of described copper strips rectangular.
Before the thickness of described copper strips be 50 microns to 100 microns.
Before the described thickness that is coated with the tin layer be 5 microns to 15 microns.
The utility model compared with prior art has tangible advantage and beneficial effect.Can know that by above technical scheme the utility model makes the thickness of belt body reduce to 60 microns to 130 microns owing to adopt technique scheme; Attenuate photovoltaic welding belt thickness; Meanwhile, the solderability of welding is good, tensile strength is high, and elongation and resistivity all can fully satisfy the practical applications needs.
In sum, the utility model really belongs to innovation on the kenel of space, and has the multinomial effect of enhancement than existing product, and simple in structure, is suitable for practicality, has the extensive value of industry.It is in limited field, technical development space; No matter structurally or bigger improvement all arranged on the function; And have large improvement technically, and produced handy and practical effect, and have the effect of enhancement really; Thereby being suitable for practicality more, really is the new design of a novelty, progress, practicality.
Above-mentioned explanation is merely the general introduction partly of the utility model technical scheme characteristic; For making the professional and technical personnel can more know the technological means of understanding the utility model; And can implement according to the content of specification, below with the preferred embodiment of the utility model and conjunction with figs. specify as after.
The embodiment of the utility model is provided by following examples and accompanying drawing thereof in detail.
Description of drawings
Fig. 1 is the cross-sectional structure sketch map of the utility model.
Among the figure, belt body 1, copper strips 11, be coated with tin layer 12.
Embodiment
Below in conjunction with accompanying drawing and preferred embodiment, to its embodiment, structure, characteristic and the effect thereof that proposes according to the utility model, specify as after.
See also shown in Figure 1; The novel thin film solar cell photovoltaic welding device of the utility model; Include the belt body 1 of longitudinal extension, said belt body 1 comprises copper strips 11, and 11 faces are provided with and are coated with tin layer 12 outside copper strips; The thickness of belt body 1 is 60 microns to 130 microns, and the width of belt body 1 is 1.5 millimeters to 8 millimeters.The thickness of copper strips 11 is 50 microns to 100 microns, and the cross section of copper strips 11 is rectangular, and the thickness that is coated with tin layer 12 is 5 microns to 15 microns.
It is that 14 millimeters to 200 millimeters copper content is at 99.9% above copper strips that copper strips adopts thickness; Adopt repeatedly calendering and annealing in process; The copper strips thickness that obtains is 50 microns to 100 microns, copper strips be coated with that the tin layer combines closely, the resistivity of copper strips can fully satisfy the practical applications needs.
The above; It only is the preferred embodiment of the utility model; Be not that the utility model is done any pro forma restriction; Every technical spirit according to the utility model all still belongs in the scope of the utility model technical scheme any simple modification, equivalent variations and modification that above embodiment did.
