Abstract
A high-absorption interconnection welding strip comprises a welding strip body, and is characterized in that a plurality of tooth tips are longitudinally arranged on the upper surface of the welding strip body, a dip angle of each tooth tip ranges from 30 degrees to 60 degrees, and the tooth width of each tooth tip ranges from 150 microns to 130 microns. Due to the fact that the tooth tips are arranged on the welding strip body, sunlight penetrates through a glass plate of a photovoltaic battery and then enters the photovoltaic battery, and light rays irradiating on the tooth tips are reflected to irradiate into the glass plate again. Most light rays irradiating into the glass plate again are not vertical to a plane where the glass plate is located, so the light rays are secondarily reflected to a solar panel of the photovoltaic battery, and absorbed and transformed by the solar panel of the photovoltaic battery. Transformation efficiency of the photovoltaic battery is improved by 1% to 3% compared with the transformation efficiency of an original structure.
Description
Technical field
The utility model relates to a kind of height for connecting the photovoltaic cell unit and absorbs the interconnecting strip welding.
Background technology
Photovoltaic cell has good welding performance with welding, be by oxygen-free copper after shearing is drawn over to one's side or is rolling, be coated with the tin layer on the surface and form.Wherein, be used for the welding that the cell piece monolithic welds and series connection is welded and be called busbar; The welding that is used for the connection battery assembly module is called interconnecting strip.Interconnecting strip is light tight, so the part that is hidden by interconnecting strip on the cell panel of photovoltaic cell can't be electric energy with light energy conversion, causes the photovoltaic cell transformation efficiency low.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of height that improves the photovoltaic cell transformation efficiency and absorbs the interconnecting strip welding.
The utility model is achieved in that
A kind of high absorption interconnecting strip welding comprises the welding body, and its special character is: longitudinally be provided with a plurality of tip surfaces at welding body upper surface, the inclination angle of described tip surface is 30 °～60 °, and the facewidth of tip surface is 150 μ m～130 μ m.
The inclination angle of described tip surface is 30 °, and the facewidth of tip surface is 150 μ m, to reach best reflecting effect.
The cross section of described tip surface is isosceles triangle.
Described tip surface and welding body are integrated.
Be provided with on described tip surface surface and be coated with the tin layer, get rusty to avoid tip surface.
The beneficial effects of the utility model are:
Owing at the welding body tip surface is set, after the glass plate of sunlight by photovoltaic cell enters photovoltaic cell, being radiated at light on the tip surface is reflected and again injects glass plate, because it is not vertical with plane, glass plate place again to inject most of light of glass plate, therefore, light is absorbed conversion by the cell panel of secondary reflection to photovoltaic cell by the cell panel of photovoltaic cell, and the photovoltaic cell transformation efficiency improves 1%～3% than original structure.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the vertical view of Fig. 1;
Fig. 3 is solar radiation line map of the present utility model.
Among the figure: welding body 1, tip surface 101 is coated with tin layer 2, photovoltaic cell 3, glass plate 301, cell panel 302.
Embodiment
As shown in Figure 1 and Figure 2, this height absorbs the interconnecting strip welding and comprises welding body 1, longitudinally rolls by mould at welding body 1 upper surface and forms a plurality of tip surfaces 101, and tip surface 101 is integrated with welding body 1, is provided with on described tip surface 101 surfaces and is coated with tin layer 2.The cross section of described tip surface 101 is isosceles triangle, and its inclination angle is 30 °～60 °, and the facewidth of tip surface 101 is 150 μ m～130 μ m.In the present embodiment, the inclination angle of described tip surface 101 is 30 °, and the facewidth of tip surface 101 is 150 μ m.
As shown in Figure 3, because when the sunlight vertical sand shooting enters photovoltaic battery 3, photovoltaic cell 3 transformation efficiencies are the highest, therefore, take this state as example, the solar radiation circuit is described: sunlight is after vertically the glass plate 301 by photovoltaic cell 3 enters photovoltaic cell 3, being radiated at the light that is coated with tin layer 2 on corresponding with tip surface 101 is reflected, and again inject glass plate 301 with 60 ° incidence angle, part light in air-glass interface by the cell panel 302 of secondary reflection to photovoltaic cell 3, by the cell panel 302 of secondary reflection to photovoltaic cell 3, the light that is reflected back is absorbed by cell panel 302 and transforms a part in glass-Air Interface in the remaining light.
