It is very big.The production technology of the tin lead layer of photovoltaic welding belt has hot dipping coating and galvanoplastic at present, and both techniques are all conventional lifes
Production. art.Wherein, hot dipping coating is that the matrix copper band that will be prepared is dipped in by guide wheel in the solution configured, is helping weldering
Reacted in the presence of agent with alloy molten solution, alloy molten solution is attached to matrix surface naturally, is cooled to solid in atmosphere, it is this
The coating that hot dipping coating technique is made is also easy to produce the surface defect of roughness, and the uniformity of coating is deteriorated, during welding with electricity
The contact surface of pond piece is reduced, and heat transfer is slow, influences welding quality, if copper strips can not be completely covered in another coating, copper strips is easily oxidized,
Appearance damage, solderability is poor, easily in welding process the problems such as generation rosin joint；Electroplating technology is then electrochemical process, be with
The technique being encapsulated into alloy based on electrochemical redox theory on copper strip surface, because electrochemical process in fact is, it is necessary to make
With more acid, aqueous slkali, environmental pollution is easily caused, cost is higher.
The content of the invention
In view of the above-mentioned problems, it is an object of the invention to provide a kind of preparation method of photovoltaic welding, can be preferable
Ground solves the lack of homogeneity and problem of environmental pollution of photovoltaic welding belt, and photovoltaic welding belt coating is carried out using magnetron sputtering membrane process
Processing, so both can effectively improve the solderability of welding, can reduce environmental pollution problem again.
In order to solve the above technical problems, a kind of technical scheme for using of the present invention for：
A kind of preparation method of photovoltaic welding, comprises the following steps：Clean the pollution that base material removes copper strip surface
Thing；Magnetron sputtering forms coating on base material, cooling, photovoltaic welding is made.
Preferably, the base material after cleaning is placed on magnetron sputtering shape in the target magnetic control sputtering filming equipment of high vacuum dual chamber six
Into the coating.
Preferably, the gas used in magnetron sputtering is Ar2。
Preferably, using target of the leypewter as magnetron sputtering, the coating is tin lead layer.It is it is highly preferred that described
The mass percent of tin is 60% in leypewter, and the mass percent of lead is 40%.
Preferably, the base material is copper strips.It is highly preferred that described copper strips is using TU1, the anaerobic of purity >=99.97%
Copper.
Preferably, the thickness deviation of the photovoltaic welding is ± 0.002mm.
The present invention uses above-mentioned technical proposal, has the following advantages that compared with prior art：Photovoltaic welding belt uses magnetron sputtering
Coating is formed, alloy deposition speed is fast, base material temperature rise is low, damage to film layer is small；Film layer is combined preferably with base material；Film layer purity
