Abstract
The invention relates to the field of a packaging material for a photovoltaic component, in particular to a bus bar for a photovoltaic component and a component of the same. The bus bar comprises a substrate, wherein the surface of the substrate is provided with an insulating area and a weldable area; and the surface of the insulating area is covered by an insulating material layer, and the weldable area is covered by a weldable layer. Good insulation between bus bars as well as between bus bars and battery strings can be realized under conditions with no additional insulating material or packaging process. Meanwhile, the design area of the component can be reduced, the component laminating process can be optimized, and the reliability of the component can be improved.
Description
Technical field
The present invention relates to photovoltaic module and use the encapsulating material field, particularly a kind of photovoltaic module busbar and assembly thereof.
Background technology
Busbar is a part in the photovoltaic module, and it mainly as the circuit linkage unit of collected current, is specially the lead-out wire unit that conflux unit and internal electric energy between the battery strings outputs to terminal box in photovoltaic component encapsulating technique.
General busbar is for being coated with the tin copper strips, and its structure is convenient welding as shown in Figure 1, and its base material 1 is 99.9% red copper, and upper and lower surface is coated with the common 60Sn40Pb of SnPb alloy 2() or SnCu alloy 2(be generally 96.5Sn/3.0Ag/0.5Cu).Because the lamination between the battery strings needs, can occur intersect 9 between the busbar, have between busbar and other the materials such as battery, EVA or backboard and contact, as shown in Figure 4, for avoiding that unnecessary accident occurs, need insulation between the busbar or between busbar and other material; Because busbar integral body can conduct electricity, thus between the busbar of the prior art or the insulation between busbar and the other materials generally be that mode by mutual isolation is achieved, but this mutual isolation need to increase extra insulating material and packaging technology; Busbar is when drawing, for containing the contact of aluminium backboard so that busbar is got along well, normally by realizing its insulation each other at backboard fluting 7, such technological operation difficulty is large, and causing easily the large-area blemish of backboard, insulation effect is also bad, simultaneously, busbar intersects 9 parts need to increase extra insulating material, brings difficulty for staff's operation and laminating technology.
Summary of the invention
Technical problem to be solved by this invention is: provide a kind of insulation effect good, can improve photovoltaic module busbar and the assembly thereof of assembly reliability.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of photovoltaic module busbar, this busbar comprises base material, but described substrate surface has insulation layer and weld zone; The insulation layer surface is covered with insulation material layer, but the surface, weld zone is covered with solderable layer.
The interlude of described busbar substrate surface is insulation layer, but two ends are the weld zone, and this busbar can be realized between the busbar, the good insulation between busbar and the battery strings.
Described base material is copper, and the material of solderable layer is tin or ashbury metal; Insulation material layer is a kind of in insulating tape, insulating varnish or the ambroin; Ambroin is fluorine film plastics or insulation PET.
A kind of photovoltaic module busbar, this busbar comprises base material, and described substrate surface has solderable layer, and the solderable layer surface has insulation material layer; Described base material is copper, and the material of solderable layer is tin or ashbury metal; Insulation material layer is a kind of in insulating tape, insulating varnish or the ambroin; Ambroin is fluorine film plastics or insulation PET; The surface of this busbar has insulation material layer, if need welding at this insulation material layer partial portion, then only needs to remove insulation material layer at the position of needs welding and gets final product.
A kind of photovoltaic module comprises battery strings and busbar, and battery strings connects by busbar, and described busbar is the photovoltaic module busbar described in the technical scheme of the present invention; Battery strings is encapsulated between panel and the backboard, and battery strings is electrically connected by busbar and electric energy is drawn backboard.
Busbar of the present invention can be under the condition without extra insulation material and packaging technology, realizes between the busbar, the good insulation between busbar and the battery strings; Simultaneously, busbar of the present invention only needs to crack at backboard and can realize good insulation between busbar and the backboard when drawing, the blemish at the place that reduced to crack on the backboard; Busbar of the present invention can dwindle on the whole photovoltaic module design area, optimized the assembly laminated process, improved assembly reliability, reduced the component power rate of decay.
