Background technology
Along with the fast development of World Economics, energy resource consumption is increasing, countries in the world all the demand new forms of energy application and popularize.Because the greenhouse gas effect that CO2 emission causes causes global warming and causes natural calamity, countries in the world are especially strong to the demand of the regenerative resource of cleaning.Since the global crisis that U.S.'s subprime crisis in 2007 causes spread and enlarges, for stimulating economic growth, each state had all passed through the measure that regenerative resource is used in more positive encouragement.U.S.'s Obama administration proposes to be used for clean energy resource for 1,500 hundred million dollars investment in following 10 years; European Union's target setting accounts for regenerative resource at the year two thousand twenty and uses the ratio of the energy to bring up to 20%; Japan proposes to make the newly-built dwelling house more than 70% that solar panel (about 70GW) is installed in the year two thousand thirty.For alleviating photovoltaic domestic demand deficiency, on March 26th, 2009, China Ministry of Finance announces will promote to implement " plan of solar energy roof " demonstration project.The Ministry of Finance, house and town and country construction portion unite clearly proposition in the appearance " about accelerating to advance the implementation guideline of solar photoelectric Application in Building ", enforcement " plan of solar energy roof " gives the fund subsidy, encourages technological progress and scientific and technical innovation, encouragement local government to put into effect a series of principal measures such as relevant financial support policy, the support on policy of reinforcement construction field photoelectricity Application in Building demonstration project.Present stage is actively pushed forward photoelectricity architecture-integral demonstrations such as solar energy roof, photovoltaic curtain wall in economically developed, the basic big and medium-sized cities preferably of industry; Actively be supported in rural area and the generating of remote districts development off-grid type, implement to send electricity pertinent regulations such as go to the countryside, indicated direction for especially the application of heliotechnics.With photoelectricity architecture-integrals such as solar energy roof, photovoltaic curtain walls is the breach, may allow people see many benefits of applied solar energy in a short time, also helps large tracts of land popularization from now on, excites the enthusiasm of capital of property investment field of solar energy.The new forms of energy policy of various countries perhaps will become next our one of the important policies of 15 years world developments after this that influence.Copenhagen weather meeting in 2009 has waken, has strengthened the consciousness that people pay close attention to clean energy resource once more up.Follow the application of new forms of energy and popularize, the rapid growth impetus of photovoltaic industry is further strengthened and is paid attention to.
Welding is the important raw and processed materials in the photovoltaic module welding process, and the quality of welding quality will directly have influence on the photovoltaic module collection efficiency of current, and is very big to the power influences of photovoltaic module.
Photovoltaic welding belt on the market is prepared from by the tinning technology mode by the copper base material mostly now, and this welding has just been introduced a kind of welding for preparing by the mode of copper strip surface tinning technology as patent publication No. CN102747313A; A kind of solar photovoltaic assembly the confluxes method of band and assembling solar plate thereof that publication number is the CN101488536 patent disclosure, use also be the welding of copper strips tinning prepared.The welding of tinning prepared, tin thickness are inhomogeneous easily, produce problems such as list edge, copper scale and variable color, are easy to generate pin hole and heavy tin phenomenon during welding, and solderability is bad.
It is to adopt the mode of copper base material electrotinning to be prepared from that fraction welding product is also arranged in addition, just introduce the photovoltaic welding belt of electrotinning preparation as patent publication No. CN102254978A, the welding tin layer of this electroplating technology preparation is even, avoided tinning welding problem, the problem includes: some problems, but its surfacing, do not increase glossiness and special picture on surface, can not realize the maximum power of cell panel.
Patent publication No. CN102790132A introduced a kind of patterning welding device, use the method for its serial connection and with its prepared solar panels, the welding surface that this mode prepares is through behind the patterning, can effectively reduce sunlight because the loss of reflection, increased the power of preparation cell panel, but it is to be connected to carry out patterning on the battery sheet after the tin layer forms, and this can destroy the tin layer and can cause the latent of battery sheet to split and fragmentation.
The utility model content
The technical problems to be solved in the utility model is: increased the loss of sunlight for the reflection that overcomes welding, influence the generated output of photovoltaic cell component, perhaps existing welding can reduce the reflection loss of sunlight, but the tin layer of welding is easily destroyed, even the battery sector-meeting is latent splits or broken deficiency, the utility model provides the welding that improves photovoltaic cell component power, and the surface of base band has the decorative pattern of special construction, is electroplate with tin or ashbury metal layer then.
The technical scheme that its technical problem that solves the utility model adopts is: the welding that improves photovoltaic cell component power, comprise the conduction base band, described base band is the metal or alloy material, described conduction base band has two wide, wherein at least one wide mask has decorative pattern, described decorative pattern has the sunlight that can improve through welding reflection at the glass of photovoltaic cell component and the sunk structure of air interface layer generation total reflection ratio, and described conduction base band surface electrical is coated with solder layer.Described wide face is meant two the welding surfaces relative with the two sides of welding thickness direction.
