Abstract
The invention belongs to the technical field of novel photovoltaic energy, and relates to a key component used in a solar cell assembly, in particular to a bijection type reflecting solder strip. The bijection type reflecting solder strip comprises a film substrate, wherein a film sticking layer is fixed on the bottom surface of the film substrate; the top surface of the film substrate is provided with a plurality of projections which are connected integrally with the film substrate and are formed uniformly; each projection has a regular rectangular pyramid structure; a metal layer is jointed to the upper surface of the film substrate. By adopting the reflecting solder strip, light sources are utilized to the maximum extent; meanwhile, power loss in a conversion process is reduced, the surface shading portion of a solar cell is reduced, and the power generation conversion efficiency is increased.
Description
Technical field
The invention belongs to photovoltaic technical field of new energies, relate to a kind of critical component using in solar cell chip module, specifically the reflective welding of a kind of correlation type.
Background technology
Solar cell is a kind of very promising novel power supply, and it has permanent, spatter property and the large advantage of flexibility three.Solar battery life is long, as long as the sun exists, solar cell just can once be invested and be used for a long time; Compare with thermal power generation, nuclear energy power generation, solar cell can not cause environmental pollution; Solar cell can be realized large, medium and small combination easily, arrives greatly the medium-sized power station of gigawatt, and little of a solar battery group for a family, this is that other power supply is incomparable.
Cell piece as photovoltaic module core has been the emphasis that whole photovoltaic industry is paid close attention to, the generating of existing cell piece is subject to light source restriction (cloudy day, night and light transmittance), transition loss (loss of electric power course of conveying) and surface area (shading light part of front conductor wire) to affect its generating efficiency to only have with 20%, the highest 25% the conversion efficiency that also can only reach of experimental data in laboratory, how maximum using light source, reduce transfer process power consumption, reduce cell piece surface shading light part and improve generating conversion efficiency, will be the key of later stage solar power generation development.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, provide a kind of correlation type simple in structure, ingenious, rational reflective welding, this reflective welding energy maximum using light source, reduce power consumption in transfer process simultaneously, reduce cell piece surface shading light part and improve generating conversion efficiency.
According to technical scheme provided by the invention: the reflective welding of a kind of correlation type, be characterised in that: comprise film matrix, described film matrix bottom surface is fixed with album leave rete, film matrix end face has and is connected with film matrix one and some projections of uniform setting, described in each, projection is square cone structure, in square cone convex surfaces and film matrix upper plane, laminating arranges layer of metal layer, and described layer on surface of metal forms correlation reflective surface.
As a further improvement on the present invention, the thickness of described film matrix is 0.01mm ~ 0.5mm, and width is 1mm ~ 50mm.
As a further improvement on the present invention, the thickness of described album leave rete is 0.01mm ~ 0.1mm.
As a further improvement on the present invention, the thickness of described metal level is 0.0001mm ~ 0.05mm.
The present invention compared with prior art, advantage is: it is direction that Light Source Compensation and light source maximum using are take in the present invention, set about changing existing solar power generation Light Source Compensation problem, rationally abundant maximum using light source, thereby increase solar power generation cell sheet intensity of illumination and area, reduce the conversion efficiency loss that is subject to external light source restriction and brings.The water caltrop face of the reflective welding utilization of correlation type uniqueness can carry out effectively correlation mutually by accepting light source, and form refraction and reflect the multiple light source repeatedly of mutually interfering, single light source can be amplified and is reflected into multiple tracks light source, and realize full dispersion to cell piece surface in unique mode, form strong Light Source Compensation and obtain higher conversion efficiency with this.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
Below in conjunction with concrete drawings and Examples, the invention will be further described.
As shown in Figure 1, comprise film matrix 1, album leave rete 2, metal level 3, correlation reflective surface 4, projection 5 etc.
As shown in Figure 1, the reflective welding of a kind of correlation type of the present invention, comprise film matrix 1, described film matrix 1 bottom surface is fixed with album leave rete 2, film matrix 1 end face have be connected with film matrix 1 one and uniform setting some protruding 5, described in each, projection 5 is square cone structure, and in square cone projection 5 surfaces and film matrix 1 upper plane, laminating arranges layer of metal layer 3, and described metal level 3 surfaces form correlation reflective surface 4.
The thickness of described film matrix 1 is 0.01mm ~ 0.5mm, and width is 1mm ~ 50mm.
The thickness of described album leave rete 2 is 0.01mm ~ 0.1mm.
The thickness of described metal level 3 is 0.0001mm ~ 0.05mm.
The height of product protrusions 3 of the present invention can be designed as 5% ~ 50% of film matrix 1 thickness according to actual operation requirements.
The generating of existing cell piece is subject to light source restriction (cloudy day, night and light transmittance), transition loss (loss of electric power course of conveying) and surface area (shading light part of front conductor wire) to affect its generating efficiency to only have with 20%, the highest 25% the conversion efficiency that also can only reach of experimental data in laboratory, its limitation has limited the development of existing industry greatly, how maximum using light source, reduce transfer process power consumption, reduce cell piece surface shading light part and improve generating conversion efficiency, will be the key of later stage solar power generation development.
It is direction that Light Source Compensation and light source maximum using are take in the present invention, set about changing existing solar power generation Light Source Compensation problem, rationally abundant maximum using light source, thus solar power generation cell sheet intensity of illumination and area increased, reduce the conversion efficiency loss that is subject to external light source restriction and brings.The water caltrop face of the reflective welding utilization of correlation type uniqueness can carry out effectively correlation mutually by accepting light source, and form refraction and reflect the multiple light source repeatedly of mutually interfering, single light source can be amplified and is reflected into multiple tracks light source, and realize full dispersion to cell piece surface in unique mode, form strong Light Source Compensation and obtain higher conversion efficiency with this.
