Description
Technical field
The present invention relates to a kind of welding plant used for solar batteries, relate to the invention of a kind of copper-aluminum composite solar cell photovoltaic welding aspect more precisely.
Background technology
Photovoltaic welding belt is the welding plant being used on photovoltaic module, mainly plays the effect connecting conduction. The critical technical parameter of welding device comprises weldability, tensile strength, unit elongation, resistivity. Welding device conventional at present is the copper strip surface at a kind of high-elongation, high tensile, high connductivity, and the method being coated with tin by heat is prepared from. Along with the raising of solar panel transformation efficiency, increasing by the electric current of welding inside, therefore just require that the conductive area of welding constantly increases, but the increase along with welding thickness, cost also can increase, it is thus desirable to propose the welding of a kind of low cost, high connductivity area, to solve the problem in current solar-photovoltaic technology field.
It thus is seen that above-mentioned existing welding device still has many defects, it is necessary to improved.
