Description
Technical field
The invention belongs to Photovoltaic new energy technical field, relate to a kind of critical component used in solar cell chip module, specifically a kind of reflection-type reflective solder strip.
Background technology
Solar cell is the very promising novel power supply of one, 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 Long-Time Service; Compared with thermal power generation, nuclear energy power generation, solar cell can not cause environmental pollution; Solar cell can realize large, medium and small combination easily, the large medium-sized power station to gigawatt, and little of the solar battery group only 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, existing cell piece generating affects its generating efficiency by 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 side conductive line) and only has with 20%, the experimental data in laboratory is the highest also can only reach 25% conversion efficiency, 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, there is provided a kind of structure simple, ingenious, rational reflection-type reflective solder strip, this reflective solder strip is assembled in photovoltaic module, surface configurations different after accepting light source can allow light source form different reflection, correlation and refraction, and form the light source repeatedly of mutually interfering, single light source can be amplified and be reflected into multiple tracks light source, form strong Light Source Compensation.
According to technical scheme provided by the invention: a kind of reflection-type reflective solder strip, be characterised in that: comprise film matrix, described film matrix bottom surface is fixed with album leave rete, film matrix top is formed with the bulge-structure be connected with film matrix one, bulge-structure surface is provided with layer of metal coating, metal coating surface forms reflective surface, and described bulge-structure comprises first protruding and the second projection being interconnected setting, and the described first structure that is protruding, the second projection is inverted v-shaped structure.
As a further improvement on the present invention, distance between the summit of adjacent two the first projections on same cross section is 0.01mm ~ 0.15mm, described first projection comprises two crownings about the first protruding top margin symmetry, and the place of being interconnected of two described crownings is arc transition structure, the radius of this circular arc is 0.001mm ~ 0.01mm; The height of described second projection is less than the height of the first projection.
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 coating is 0.0001mm ~ 0.05mm.
The present invention compared with prior art, advantage is: the present invention with Light Source Compensation and light source maximum using for direction, set about changing existing solar power generation Light Source Compensation problem, rationally abundant maximum using light source, thus increase solar power generation cell sheet intensity of illumination and area, reduce the conversion efficiency loss brought by external light source restriction.Reflection reflective solder strip utilizes unique surface configuration can carry out effective reflection, correlation and refraction mutually by accepting light source, and the multiple light source repeatedly that shape is interfered mutually, single light source can be amplified and be reflected into multiple tracks light source, and realize full dispersion to cell piece surface in the mode of uniqueness, form strong Light Source Compensation and obtain higher conversion efficiency with this.
